TLT-Turbo and Mosen paper on the new MoJet® Fan presented at the 2022 Tunnel Safety and Ventilation Conference

Mosen’s Fathi Tarada, presented a paper at the annual Tunnel Safety and Ventilation Conference in Graz, Austria. The paper, which Tarada co-authored with Mosen’s Pier Bertacche and Product Manager of the Tunnel & Metro Business Segment at TLT-Turbo, Lars Lehmann, was titled: “Measurements and CFD Calculations with a MoJet and Conventional Fan”.

The three-day conference event was well attended with industry experts able to meet face to face after the conference’s four year hiatus.

TLT-Turbo and Mosen also exhibited at the event, with a MoJet® fan model on display, providing an opportunity to engage with interested colleagues in the industry as well as prospective customers. The display model provided visitors with a chance to see the technical details of the MoJet®, to find out how the special nozzle geometry redirects the air jet away from the tunnel ceiling. Visitors were also able to appreciate the MoJet’s® scale. Being the same height as a conventional Jet Fan, it provides a distinct advantage over the ‘slanted’ silencer design.

Along with Tarada and Lehmann, TLT-Turbo tunnel ventilation experts, Till Weishaar and Sander Wirth were in attendance to provide insight into the ways in which the MoJet® is redefining tunnel ventilation.

Modular Design Redefines Mine Ventilation Efficiency and Availability

TLT-Turbo have released a modular mining ventilation fan concept that simplifies the planning of ventilation systems for customers while still providing the benefits that are synonymous with TLT-Turbo products including increased efficiency and lower power consumption. The Modular Mining Fan concept offers a range of modular solutions that cater to almost every ventilation requirement and aims to set a new standard for mine ventilation innovation.

The range offers a modular design that results in a well-engineered and efficient ventilation system at lower operational and maintenance costs. Customers have the flexibility to order required units and build on the system as their requirements grow – resulting in lower initial expenditure with more economical options for system expansion.

German engineering and extensive R&D have resulted in the highest product quality. This, paired with TLT-Turbo’s field-proven technology, provides a high-end pre-existing solution which means that mines will not incur the design and engineering costs that are usually associated with bespoke ventilation installations.

The modular concept makes it extremely convenient for customers in the mining industry to plan, design and optimize their ventilation systems to optimally benefit their operations. The modular approach eliminates guess work and ensures that the entire system can be planned to deliver predictable and accurate performance.

The modular design offers seven base fan sizes combined with six different hub sizes to ensure the right fit for all requirements. Numerous customizable and adaptable parts offer flexibility for specific customer needs. Add-ons have been developed for all seven base sizes allowing for modular pre-existing upgrades to meet individual requirements.

The modular components are designed to slot together, and no additional engineering is needed to ensure that different modules fit together to suit a specific operating environment. The advanced design ensures total fan efficiency of up to 90%, lowering the operating costs while maintaining full performanceThis entire offering is available at lower initial costs with short lead times for supply.

All the modular components can be manufactured simultaneously and are commissioned and installed once completed. Expansion of an existing TLT-Turbo Modular Mining Fan system is a simple process as new components are slotted into the existing system with minimal effort. Typically, ventilation systems need to grow or be upgraded as production demands increase. Where a major overhaul would usually be required, TLT-Turbo’s modular installation can be expanded by installing additional components to the existing system to scale up ventilation capacity or replace existing modules with higher specifications to optimise or upgrade the system.

With the modules being manufactured at state-of-the-art TLT-Turbo manufacturing facilities, customers can be assured of the highest quality end product. Continual monitoring, testing and quality checks are conducted at every stage of the manufacturing process. Well considered opportunities for varied combinations ensure shorter manufacturing and delivery lead times at lower costs to get your project running faster and smoother.

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.”

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.

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.

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.
