MVR Fans Next Generation of Mechanical Vapour Recompression
TLT-Turbo has launched a new range of mechanical vapour 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 vapour 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 fans were rolled out in 2016 while continual product improvement has remained a focus area for the company.
“MVR fans have been available in the market for some time but instead of just following the trend, the firm 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 Vapour 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 the company’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 of the firm’s key objective for continual innovation.
The implementation of hybrid ceramic bearings is a key differentiator of the company’s 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 the company’s fans are life time greased and can be operated for up to 10 years without requiring maintenance, states the company. To enhance this benefit for clients, the firm 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 optimised 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 the firm’s products. These factors allow for operation of the fan below critical speed which ensures both reliability and safe operation, adds the company.
“Reliability and safety are key concerns for our clients and the company 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 firm’s 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. This 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, the company’s objective was to offer our clients a mechanical vapour recompression solution that would outperform what was currently available in 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 the firm as a world class fan manufacturer and global service organisation.”
