TLT-Turbo GmbH Continues to Show Resilience Through COVID-19 Pandemic

Following the first official response statement on the global coronavirus pandemic, TLT-Turbo has continued to prove operational resilience in its operations across the globe. This is largely due to the efforts of the TLT-Turbo global team and the implementation of various innovative measures including remote service support and virtual model acceptance testing. These factors have allowed TLT-Turbo to continue providing the high level of service that their clients have come to expect – with some formally showing their appreciation for the ways in which TLT-Turbo’s support has contributed to their operational continuity.

In the three months since TLT-Turbo released their initial COVID-19 response statement, they have announced several new contracts for high profile clients across the globe. Most notably this includes the supply of Sinter fans and two CDQ fans for various clients in China and an order for low flow MVR fans to a client in Colombia.

TLT-Turbo, Global Co-Managing Director, Rainer Redinger: “We knew that to a large extent our resilience in the face of such a significant global challenge would stem from the expertise and commitment of the TLT-Turbo global team. Securing of these orders demonstrates the perseverance of the sales representatives and engineers involved and speaks to the reliability of our products on the market. These same factors will ensure that we endure through the COVID-19 pandemic and current global market downturns and emerge stronger than ever.”

Travel restrictions imposed around the globe, posed a challenge to the delivery of
TLT-Turbo services and fans. TLT-Turbo implemented Remote Service Support that facilitates remote service, maintenance, repairs and troubleshooting. Using an audio-visual connection that allows the exchange of images and data between TLT-Turbo experts and customers, TLT-Turbo’s team can guide customers through the process of making simple repairs and adjustments in real time.

Along with this, to facilitate the delivery and commissioning of new fans, TLT-Turbo’s R&D team have also rolled out Virtual Model Acceptance Testing. TLT-Turbo made aerodynamic model acceptance measurements and final acceptance testing available for customers to attend virtually. They are now done through software that combines video conferences with a connection to virtual reality on smartphones, tablets, smart glasses or a video screen.

“This is a major advancement in the digitalization of our offering. In future, even as we move into a post-COVID world, these platforms will remain an alternative option to conventional model acceptance testing, trouble shooting, repairs, inspections and many other services for all customers as it saves them both time and money,” Mr. Redinger explains.

These efforts add to the crucial support of the regional TLT-Turbo offices across the globe that are starting to re-opening following various national lockdowns.
TLT-Turbo Africa has been operational through the continuing national lockdown in South Africa that was instituted on 26 March 2020. They have been registered as an essential service which allows for manufacturing activities with 30% of their usual staff complement per shift. “We are currently on a two-shift system of six hours per shift for operational staff. Even with limited staff, we have managed to make key deliveries to our customers,” says TLT-Turbo Managing Director, Christo Gelderblom who goes to explain that strict hygiene and safety protocols are being adhered to and that non-essential staff are still working from home. “We have received a number of orders since we returned to work and are expecting a few more in the weeks to come as South Africa’s lockdown alert levels are being lowered.”

In Korea, TLT-Turbo representatives have been able to recommence visits and meetings at client sites while adhering to strict hygiene, prevention and social distancing measures. The regional office has reported that they are almost back to business as usual while taking every measure to protect the health and safety of their staff. Their manufacturing facility continues to be fully operational.

Currently, TLT-Turbo manufacturing facilities in the USA, Germany and China are also operational. TLT-Turbo Global Co-Managing Director, Minggang Wan: “We have done everything in our power to keep our processes running as smoothly as possible. We have complied with all required hygiene regulations and have developed our own additional safety measures to ensure that our staff are taken care of. We have also ensured that our customers are able to reach us by making our team accessible on electronic platforms as they continue to work from home.”

This accessibility has allowed TLT-Turbo’s customers to continue to rely on the products and services that play a crucial role in their daily operations. Several customers have sent in words of gratitude for the role that TLT-Turbo’s products and support have played in keeping them going.

Currently, TLT-Turbo continues to encourage concerned clients and suppliers to reach out their TLT-Turbo representatives in the various regions. Locate your nearest point of contact here.

Model Acceptance Tests Go Virtual!

An important task carried out by TLT-Turbo is the conducting of aerodynamic model acceptance measurements and final acceptance tests in the presence of our customers. These tests demonstrate the aerodynamic performance of TLT-Turbo fans on a model test stand to meet the required fan characteristics.

Model tests are significantly cheaper and less complex than conducting tests on a full-size performance test stand (FSPT) such as the one that TLT-Turbo has set-up in Chengdu, China. TLT-Turbo has various model test stands at their facilities in Germany and is able to test different diameters of axial fans, centrifugal fans and full-size jet fans.

Due to the restrictions of the COVID-19 pandemic, it is not possible to host clients for witnessing tests at our R&D center in Zweibruecken. In an effort to continue providing excellent customer service and for current orders to move ahead, TLT-Turbo has found a solution – making acceptance tests available for customers to attend virtually!

Inspired by the global movement to move physical business processes such as meetings and inspections online, TLT-Turbo started looking for a software solution that would allow them to conduct virtual aerodynamic model acceptance tests.

The solution was found through software, which allows classic video conferences to be combined with a connection to virtual reality on smartphones, tablets, smart glasses, or a video screen. This makes it possible for participants in a teleconference meeting to see and experience everything as if they were nearby.

“Our team has run through the process and rehearsed internally to make sure that we are ready to fully cover every aspect of the testing and we are ready to offer this service to our clients to allow work and delivery of fans to continue,” says Dr. Sebastian Fleder, TLT-Turbo Product Manager for Aftermarket and Services. “This is a major advancement in the digitalization of our offering. In future, even as we move into a post-COVID world, this model will remain an alternative option to conventional model acceptance testing, trouble shooting, inspections and many other services for all customers as it saves them both time and money.”

TLT-Turbo India Doing their Part to Alleviate COVID-19 Burden

Like the rest of the world, India is facing the challenges of the COVID-19 pandemic and the effects of their own national lockdown. Those living below the poverty line as well as day workers and laborers have been particularly hard hit by the nationwide lockdown that started on 23 March 2020.

India’s Prime Minister addressed the nation and requested support for those in need. To facilitate donations, a special PM Office bank account was set up for individuals and organizations who wished to play their part in helping the nation’s needy.

While working from home, the team at TLT-Turbo India started discussing the unthinkable challenges facing their less fortunate fellow citizens and decided that they wanted to step up. In a moving and overwhelmingly generous gesture, the entire team decided to donate one day’s salary to the cause. This response on an individual level inspired TLT-Turbo India management to match their donations as a company. Together they reached a total amount of just over 100 000 Rupees (1300 Euro) which was deposited into the PM Office account.

“We felt a responsibility towards this cause. We are grateful to be able to continue working from home when so many others cannot work at all. The TLT-Turbo India team working from home are in contact every day and through our discussions it came to light that this cause was something we were all thinking about. I know that this amount may not be as high as some donations by larger companies, but our intent and philosophy is always do what we can to care for others and I am so proud of my team for making this happen,” says Pankaj Sohoni, TLT-Turbo India Managing Director.

Global Managing Director, Rainer Redinger applauded TLT-Turbo India for their generosity and sense of responsibility toward their fellow citizens. “Civic duty and pride are near to our hearts at TLT-Turbo. This donation demonstrates this part of our corporate culture perfectly. Throughout the COVID-19 pandemic and the various lockdowns that have been put in place across the world, the TLT-Turbo Global Team continues to show not only astounding resilience and motivation but also empathy for those who have been hardest hit. I would like to personally thank TLT-Turbo India for leading by example and for showing the world how unified action and solidarity can make a difference.”

TLT-Turbo Fan Range Redesigned to Meet Specific Mining Industry Needs

Global ventilation fans and systems manufacturer, TLT-Turbo GmbH, has announced the redesign of its Auxiliary and Booster fan range. Developed in close collaboration with clients, the new designs address both efficiency and cost effectiveness, in a versatile product range that meets the specific ventilation requirements of the mining industry.

Development of the new fan range concept began in early 2015. Following a lengthy global market study to gain an understanding of the market requirements, the range was defined in mid-2017, with fabrication of the first units taking place shortly thereafter. “The development of the Auxiliary and Booster fan range would not have been possible without the input of clients. This ensured that we focused on key market driven requirements including energy efficiency, noise reduction, cost effectiveness and turnaround time,” says Michael Minges, Technical Director at TLT-Turbo Africa, who headed up the fans’ designs.

“To sell these products we needed to ensure close customer relationships and visibility. We are striving to change the industry’s mindset on the use of such fans to ensure proper fan selection for the ventilation required. In optimizing mine ventilation, efficient, high quality Auxiliary and Booster fans can add as much value as surface fan installations.”

(Above) The new TLT-Turbo Auxiliary and Booster fan range addresses both efficiency and cost effectiveness

TLT-Turbo started commissioning of the first iterations of the fan range towards the end of 2017 within the Sub-Saharan market through its Africa office. From there, they based the development of the various fan sizes of the new range on market interest. The fan designs and their performance validation was completed at the end of July 2019. They aim to complete product roll out, with all supporting documents and certification, by the end of September 2019.

Minges explains that meeting identified market demands was the main focus of the improved designs. “As energy efficiency is one of the main drivers of industrial equipment usage, and minimum efficiency requirements on certain equipment are often legislated, TLT-Turbo identified the need and opportunity in the market for more efficient mining fans compared to what is currently in use.”

The new designs include several innovative additions to enhance performance in order to provide exceptional underground ventilation. The fan range was developed using the latest in engineering flow technology which allowed TLT-Turbo to improve the aerodynamics, and thus efficiency of the fans. A unique stator design and aerodynamic fairings, all manufactured from wear resistant composite materials, result in improved efficiencies and reduced noise levels. The modularity of the fan casings allow for quick and easy assembly with interchangeable ancillary fan parts.  The motor mounting in coherence with a machined impeller track ensures low and controllable blade tip clearances for improved performance and efficiencies. Pad mount motors are used for all fan sizes and help reduce vibration levels in the axial direction of the motor significantly which leads to longer motor bearing life and lower maintenance requirements.

(Above) The first orders for the new range were received at the end of 2017

Minges says that all possible measures are taken to ensure the highest quality and best possible performance of every fan supplied by TLT-Turbo. “All fans are ISO 5801 tested, unless the client agrees to type testing on higher volume orders. We ensure the client quoted performance is met before the fans leave the factory. Test certificates on both raw data and calculated performance can be provided on request. Fan efficiency is determined with the performance test and this quality check ensures we deliver on what we promised the client. Clients are regularly invited to witness the performance tests to sign off on acceptance. The fans also come with pressure ports that can be hooked up to a calibrated handheld measuring device to measure performance in-situ.”

In addition to performance and efficiency, ease of maintenance was also a major consideration in developing the new Auxiliary and Booster range. The modularity of the product design and the interchangeable standardized parts allows for quick turnaround time on parts supply. “For example, we only have two blade types for the full product range and generally only one motor barrel per fan size accommodating various motor sizes and types. Standardization on the product is the key to successfully managing maintenance and repair as it allows ample supply of spares for companies certified to do the repair work. The design track record has indicated a longer mean time between failure (MTBF) than previous products,” Minges explains.

(Above) The new TLT-Turbo Auxiliary and Booster fan range is available to clients worldwide

The fan range is being rolled out in phases. The preliminary testing at sites located in Sub-Saharan Africa has been launched successfully. The next phase is globalization as the new range will be rolled out in the USA, Canada, Europe, Russia and Australia. Following this, product supply and support will be extended to TLT-Turbo offices in South America and India. In the interim though, Minges says that these fans can be supplied to clients worldwide from TLT-Turbo Africa.

TLT-Turbo Africa has received a number of orders for these fans since the end of 2017. These orders include South African clients seeking a solution for deepening a gold mine, and for Kamoa Copper in the DRC as an exclusive supplier. “The feedback that we have received thus far has been that the fans are meeting our and client expectations. I am proud to say that one EPC consultant used the phrase ‘super fan’ to describe the new range and indicated that he has not heard a fan of this size so quiet before,” says Minges commenting on the reception of the new range.

“The Auxiliary and Booster fan range was developed to enhance TLT-Turbo’s mining ventilation product portfolio. The product is based on historic innovative designs by the TLT-Turbo Africa R&D team. Continual product development and keeping up to date with the latest technologies is ingrained within the engineering teams of TLT-Turbo. Ensuring that innovations are market and client driven with the end result being a benefit to the industry, puts us in the forefront of advancement in ventilation solutions,” Minges concludes.

TLT-Turbo On-site Test Lab Advances Product Quality

Global ventilation fans and systems manufacturer, TLT-Turbo GmbH, has spent the past five years investing in and equipping its on-site test lab. The test lab now provides streamlined processes for research, advancing product quality and expanded capabilities for material testing. With a focus on particle impact wear testing, the test lab is driving innovation forward at TLT-Turbo as the results help improve product reliability, quality and performance in their final operating environment.

Patrick Baumgärtner a Research and Development Engineer – and expert in wear and corrosion protection – at TLT-Turbo, has played an instrumental role in building up the test lab – located at the TLT-Turbo Development Centre in Zweibruecken, Germany – to its current capabilities. Together with Sabine Groh, Industrial Fans Product Manager at TLT-Turbo, they have been spearheading the current research.

Currently, the core field of research at the test lab is the testing of new wear-resistant materials and coatings for fan components. Baumgärtner says that the testing takes place in the lab’s solid particle impact wear test bench. There, various types of dust or abrasive particles are blasted onto the test material, varying the angle and speed of the blasting to observe the resulting wear. “We also carry out caking tests in which we select, for example, anti-adhesive layers for our fans, in order to find suitable solutions for customer applications. A further main focus is the analysis of process residues that can have an abrasive or corrosive effect. Here the composition, size distributions, pH value and conductivity in the eluate are determined,” Baumgärtner explains.

(Above) Part of the materials testing laboratory in Zweibrücken

TLT-Turbo’s approach is to continuously test materials, coatings and components in order to produce fan components that are designed for performance excellence in any operating environment – no matter how abrasive. This testing is applied to current and new products in development but also to samples that are brought in from client sites in order to establish the wear patterns caused by their specific environment. In this way, TLT-Turbo is able to provide each client with a customized solution that will last longer and require less maintenance. 

The test lab now offers facilities for metallography, a stereomicroscope, a pycnometer for determining the density of materials and coatings, and an automated solid particle impact wear test bench. “The capabilities of the test lab open a lot of doors for advanced research that will make a positive contribution to the engineering community at large as well,” says Baumgärtner. “Under my supervision, studies and thesis research takes place in the laboratory in cooperation with local colleges and universities. For me, this is the basis for successfully researching and developing new solutions in our field.”

According to Groh, the test lab has almost endless possibilities for the improvement of product delivery to clients. “Our customers are often operating TLT-Turbo fans in abrasive and/or corrosive environments. To develop suitable solutions that match the wear resistance against particle impact we use our automated solid particle impact test bench. Compressed air accelerates a defined mass flow of abrasive particles to velocities up to 300 m/s and propels them onto a piece of sample material. This leads to material loss and wear that we can examine.  It is even possible to use original dust from a customer’s plant to evaluate the most suitable solution for them. By varying the impact angle we can observe system characteristic wear curves. With this knowledge we can provide customized solutions for many processes.”

(Above) Exchangeable impeller blade exposed to massive wear

These customized solutions can be best illustrated in the selection of coatings. This, says Groh, has an immensely positive impact for TLT-Turbo clients. “If we were to propose a new coating for a customer, the wear rate of the coating would be determined first. That is the main scientific-based decision criteria for wear resistant coatings. If the coating has a superior wear rate compared to other coatings or at least a wear rate that is on par with other coatings and another beneficial quality such as anti-stick effect, corrosive resistance or a cost advantage it will be implemented into TLT´s coating portfolio.”

Groh says that they have also conducted tests that have led to the development of completely new proprietary coatings. “During the manufacturing process, coatings were tested to see the influence of welding heat on coating qualities – such as the development of cracks – to ascertain how to avoid damage caused by heat or weld splashes. We conducted research and testing on combining welded coatings and thin layer coating into a Hybrid Coating which can dramatically increase the operational lifespan of TLT-Turbo fans at their clients’ plants.”

This is one of numerous examples of how TLT-Turbo’s testing capability can positively impact ventilation systems across all applications. “Due to the broad database of wear tests on various materials and coatings, we are able to offer tailor-made wear protection solutions for various processes of our customers,” Baumgärtner acknowledges.

(Above) Blasting nozzle and sample holder of test bench

Groh agrees, adding that the wide variety of chemical compositions and coating conditions such as acceleration of coating powder and heat development make it extremely difficult to objectively find the best coating by carrying out testing at a customer plant. “The process of reaching just initial findings in these conditions is very time consuming. In addition to this, there is a broad variety of conditions to contend with at different customer plants that hinder an accurate comparison of different coatings at different plants. If you test different coatings on one machine you might get a rough estimation what coating is superior, however different wear rates of coating cause imbalances in the impeller and vibrations at the fan.”

She elaborates by explaining that finding a precise comparative measurement on different coatings is impossible without being able to analyse how the wear rate changes at different angles. “At the test lab we can control the conditions to find precisely what we are looking for in a shorter timeframe. Additionally we are able to replicate the fan’s operating environment. We can run tests using dust collected from the client site while simulating particle speeds that match the client’s environment to precisely simulate wear rates.”

In the laboratory environment, the TLT-Turbo team is also able to determine additional coating properties as they have the capability to run additional experiments, e.g. corrosive resistance, anti-stick effect, robustness, heat resistance, suitable application methods, and combination possibilities like hybrid coatings.

The test lab has afforded TLT-Turbo engineers a deeper understanding of the mechanisms behind wear and the effects of specialized solutions. This has led to new approaches in product advancement and development that are grounded in providing solutions that meet market requirements.

“The analysis of residues from plants has a great influence on product development as we are making more informed decisions when choosing materials for corrosive and abrasive environments,” says Baumgärtner.

This has also had an impact on TLT-Turbo’s aftermarket service offering. The test lab, has allowed for new customer services can be generated, such as the performance of specific tests for customers. “The development of new solutions for specific customer problems is now much faster and more accurate. Also the suitability of low cost approaches or solutions that allow for wear induced damages to be repaired on-site integrate effortlessly into TLT-Turbo’s existing solutions,” Groh concludes.

The test lab enables TLT to continuously improve their solution portfolio for different customer problems with a focus on wear. The combination of understanding the client’s exact requirements and challenges and having a tool that allows engineers to find the best solutions from a scientific basis are a key factor for success in the market and play an important role for TLT-Turbo’s on-going product development and quality client delivery.

The first MVR fans were rolled out in 2016 while continual product improvement has remained a focus area for TLT-Turbo.

“MVR fans have been available on the market for some time but instead of just following the trend, TLT-Turbo took time to ensure that we came to the market with a completely new, state of the art MVR solution,” says Mario Schmidt, Head of TLT-Turbo’s Vapor Fans business segment. “And we continue to have on-going discussions and feedback exchanges with our clients worldwide in order to continuously adapt and improve our MVR offering to their requirements.”

According to Schmidt, the features of TLT-Turbo’s MVR fan, such as the lower maintenance requirements and the introduction of hybrid ceramic bearings, underscores their commitment to developing products in close alignment to their clients and their needs, and also speaks to TLT-Turbo’s key objective for continual innovation.

The implementation of hybrid ceramic bearings is a key differentiator of the TLT-Turbo MVR fan. “Our clients are amazed by the possibility of a hybrid bearing operating at high speed without circulating oil. Conventional roller bearings do not provide the required support for operating the fan in a broad operational speed range without running into harmful resonance frequencies (under critical operation). Thanks to continuous enhancement in recent years, especially through the use of ceramic materials, more effective roller bearings are available today. The use of hybrid bearings with steel rings combined with ceramic rollers has been established in many industrial applications and in the case of the TLT-Turbo MVR fan, hybrid ceramic bearings mean significantly lower maintenance requirements and better operational performance,” Schmidt explains.

The hybrid ceramic bearings used in TLT-Turbo MVR fans are life time greased and can be operated for up to 10 years without requiring maintenance. To enhance this benefit for clients, TLT-Turbo introduced an additional device to the fan’s design that allows for the bearing to be re-greased from the outside in order to further simplify maintenance and to increase the fans’ service life.

High motor speeds, a wide range of optimized impellers and the allowance for high temperature and pressure increases complement the lifetime greased hybrid ceramic bearings to ensure that clients benefit from the enhanced performance and efficiency that they have come to expect from TLT-Turbo products. These factors allow for operation of the fan below critical speed which ensures both reliability and safe operation.

“Reliability and safety are key concerns for our clients and TLT-Turbo has addressed this in the MVR fan by using high quality components. Thanks to the use of the hybrid bearings, no oil supply or oil pump is necessary which means that no oil can contaminate the product. In addition to this, the fan also features temperature and vibration monitoring and remote monitoring of the bearing is possible as well. Our entire manufacturing process is carried out according to all major quality standards, including DIN ISO 9001,” says Schmidt.

The TLT-Turbo MVR fan is suited to numerous applications in the chemical, pharmaceutical, waste water treatment, and the organic natural product production industries as well as in the food and beverage process and manufacturing sectors. “Since 2018, we have received 35 orders for MVR fans across the globe with one installation completed. Thus far, the feedback from clients has been very positive. We have received reports that the bearing temperature is considerable lower than that of other comparable MVR fans and that our fan runs with less vibration than other MVR fans,” Schmidt affirms.

“Overall, TLT-Turbo’s objective was to offer our clients a mechanical vapor recompression solution that would outperform what was currently available on the market. We have delivered a fan that requires less maintenance while providing high efficiency and reliability. This is exactly what clients would expect from TLT-Turbo as a world class fan manufacturer and global service organization.”

ACHEMA 2018 – Strong visitor Interest at the TLT-Turbo Booth

At this year’s ACHEMA 2018, we once again presented our MVR Turbo Fan for mechanical vapor recompression. This year, we demonstrated the fan to the audience with a sanded and highly polished impeller, as an example of how it is applied for use in the pharmaceutical industry.

The TLT-Turbo Mechanical Vapor Recompression (MVR) fan attracted a large number of visitors to the booth. Our engineers presented the energy-efficient process in detail to interested visitors representing the process, chemical and pharmaceutical industries.

The innovative bearing concept – a hybrid ceramic bearing that is grease-lubricated at the factory and requires neither regular oil changes nor an oil supply – aroused great interest. With this concept, maintenance and thus operating costs can be reduced significantly.

The units are available in two different versions: the basic version includes the fan on a base frame with monitoring sensors whereas the complete package contains a motor and frequency converter. Depending on the application, different stainless steel housings and impeller types can be selected. In addition to the standard impellers made of duplex stainless steel, and models made of super duplex or titanium are also available.
