“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,” argues Mario Schmidt, Head of TLT-Turbo’s vapour fans business segment.
The bearings can be operated for up to 10 years without requiring maintenance.
The fan design has been in development since 2012, after which the first case studies were carried out followed by four years of research, product testing and consultations with clients. Product launch in 2016 has been followed by continuous improvement since.
The TLT-Turbo MVR fan is suited to numerous applications in the chemical, pharmaceutical, wastewater treatment, and the organic natural product production industries as well as in the food and beverage process and manufacturing sectors.
Continues Schmidt: “Since 2018, we have received 35 orders for MVR fans across the globe with one installation completed. We have received reports that the bearing temperature is considerably lower than that of other comparable MVR fans and that our fan runs with less vibration than other MVR fans.”
