Global ventilation fans and systems manufacturer, TLT-Turbo GmbH, has announced the launch of their new Low Flow MVR Fan Series. As a more compact alternative to TLT-Turbo’s existing larger-capacity MVR range, the new low flow series promises the same uncompromising efficiency that clients have come to expect from TLT-Turbo ventilation equipment.

Having been in development for the past 18 months, this new addition to the MVR (Mechanical Vapor Recompression) range is characterized by having a significantly smaller and more compact size while still delivering higher efficiencies.

In comparison to the existing MVR range, these fans are designed for lower mass flows at medium inlet temperatures. “The maximum speed is 6500 rpm. This limitation is mainly due to the fact that there are no faster rotating motors available in this range and for this application,” explains Mario Schmidt, Head of Business Segment Vapor Fans, TLT-Turbo. He adds that this range is ideally suited to industrial applications focused on the concentration of liquids.

The new Low Flow MVR series elegantly combines all the advantages and features of all other TLT-Turbo MVR series, including maintenance-free, long wear hybrid ceramic bearings and high efficiencies as well as speed-, temperature- and vibration monitoring. The fans are designed to achieve temperature increases up to 11°C while maintaining efficiencies of up to 83%.

“The development of this range is an exceptional achievement of our R&D department and product management team. The expansion of our current MVR offering has allowed us to enter the small mass flows market which makes us more competitive.”

The design of the new series was carefully considered, ensuring that all major customer and application requirements are met. Schmidt explains that these fans are made to deliver on performance. “The fans are available 24/7 with a wide range of operating points and high efficiencies of up to 83% depending on inlet temperatures and specified temperature increases. In addition to this, the fans are VFD controlled.”

The highest quality and safety standards are met by using only high quality and proven components. The fans’ monitoring devices are included with the installation, and all models are rigorously tested, and FEM calculated. Like their larger counterparts, the Low Flow MVR Series is manufactured using hybrid ceramic bearings that are lifetime 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. “Maintenance is made even easier for our customers with the option for them to make use of our remote performance and maintenance checks.”

The new Low Flow MVR Series is manufactured at TLT-Turbo’s dedicated facility based in Germany and is available globally. An order has already been secured for the supply of TLT-Turbo Low Flow MVR fans from a globally renowned manufacturer for installation at an instant coffee production facility in Colombia. “The securing of this contract has already caught the attention of other global coffee producers and bodes well for the continued growth of our MVR division,” says Schmidt.

“TLT-Turbo is known for redefining ventilation, and this means we constantly strive to set new standards. With respect to all previous MVR series, TLT-Turbo is the first manufacturer to use hybrid ceramic bearings. In addition, all TLT-Turbo MVR fans are aerodynamically optimized and offer high efficiency. For further developments, new materials and manufacturing methods are also continually investigated to ensure that our customers benefit from the latest innovations. Our MVR range has been trusted for use in applications with stringent hygienic requirements such as highly polished impellers and housings. This, and all the other innovations showcased in the new series is the result of an almost 150-year track record in the design and production of industrial fans,” Schmidt concludes.

TLT-Turbo GmbH, a global ventilation fans and systems manufacturer, has launched a new range of mechanical vapor recompression fans, with ceramic hybrid bearings that provide an exceptionally long operational lifespan. Integrating the latest ventilation technologies, this fan offers numerous advantages regarding performance efficiency, minimal maintenance and high reliability.

The TLT-Turbo fan for mechanical vapor recompression (MVR) has been in development since 2012 since the first case studies were carried out. Following intensive discussions with clients, TLT-Turbo established that a need existed for low maintenance MVR fans. This was followed by four years of intensive research, product testing and consultations with clients. 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.”
