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.

The 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. And the range was defined in mid-2017, with the 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 rollout, 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 the efficiency of the fans.

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,” Minges said.

In addition to performance and efficiency, ease of maintenance was also a major consideration in developing the new Auxiliary and Booster range.
