The TLT-Turbo fan for mechanical vapour recompression has been in development since 2012 when 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, and continual product improvement has remained a focus area for TLT-Turbo.
Integrating the latest ventilation technologies, the fan offers numerous advantages including performance efficiency, minimal maintenance and high reliability.
“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 it came to the market with a completely new, state-of-the-art MVR solution,” says Mario Schmidt, head of TLT-Turbo Global Vapour Fans business segment.
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 the company’s commitment to developing products in close alignment to its clients and their needs, and also speaks to TLT-Turbo’s key objective for continual innovation.
“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.
“The implementation of hybrid ceramic bearings is a key differentiator of the TLT-Turbo MVR fan,” says Schmidt, adding that 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).
“In the case of the TLT-Turbo MVR fan, hybrid ceramic bearings mean significantly lower maintenance requirements and better operational performance,” he 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 fan’s 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 they have come to expect from TLT-Turbo products. These factors allow for operation of the fan below critical speed, which ensures reliability and safe operation.
The use of the hybrid bearings means no oil supply or oil pump is necessary, which means that no oil can contaminate the product. In addition to this, the fan features temperature and vibration monitoring. Remote monitoring of the bearing is also possible.
The TLT-Turbo MVR fan is suited to numerous applications in the chemical, pharmaceutical, waste water treatment, and organic natural product production industries as well as in the food and beverage process and manufacturing sectors.
“Overall, TLT-Turbo’s objective was to offer its clients a mechanical vapour 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,” concludes Schmidt.
