Ceramic bearings revolutionise MVR fans

A new range of mechanical vapor recompression (MVR) fans with ceramic hybrid bearings that promise a long operational lifespan, are now available.

The fans are said to integrate the latest ventilation technologies, with the promise of improved performance efficiency, reduced maintenance and increased reliability.

The manufacturer explains that its MVR fans have been in development since 2012, with the focus on creating a low maintenance version. The fans were rolled out in 2016 and the company aims to adapt and improve its offering, with ongoing product development.

Hybrid ceramic bearings used by TLT-Turbo are said to be a key differentiator of its MVR fan, compared to traditional MVR fans. The hybrid bearings allow for operation at high speeds without circulating oil. As no oil supply or oil pump is required, there is no risk of oil contaminating the product. The fan also features temperature and vibration monitoring, with remote monitoring of the bearing another available feature.

It has been noted that conventional roller bearings do not provide the required support for operating a fan in a broad operational speed range without running into harmful resonance frequencies, under critical operation. With the wider use of ceramic materials,  more effective roller bearings are now readily available. The company’s use of hybrid ceramic bearings has led to lower maintenance requirements and better operational performance.

The hybrid ceramic bearings used in the company’s MVR fans are life-time greased and can potentially be operated for up to ten years without requiring maintenance. The company also introduced an additional device into the fan’s design, that allows for the bearing to be re-greased from the outside, allowing for easier maintenance and increased service life.

High motor speeds, a wide range of optimised impellers and an allowance for high temperature and pressure increases, are all aimed at enhancing the performance and efficiency of the products. These factors allow for operation of the fan below critical speed which ensures both reliability and safe operation.

The fan can be used for applications in the chemical, pharmaceutical, wastewater treatment, and organic natural product production industries as well as in the food and beverage process and manufacturing sectors.
