Mechanical Vapour Recompression (MVR)

 
Piller was the first company that introduced centrifugal fan solutions for the process of mechanical vapour recompression as used in evaporation units.

Patented bearings and purposely developed high-performance impellers make Piller the leading manufacturer of MVR fans. 
Applications for Standard MVR fans: single, double stage max 3 stages
Volume:               2 t/h up to 150 t/h
Pressure:             vacuum up to 1.49 bar (5barg)
Delta T per stage 7-11 °C average 9 °C
 

Multi Stage Steam Recovery
( MSSR)

MVR fans can be connected in series to provide additional direct compression of the evaporated steam and raise it to higher temperatures, so it can be reused in the heating process in the evaporator. Multiple MVR’s can offer significant energy savings and short term return on investments.
Applications: (3 to 8 stages)
Volume:               5 t/h up to 150 t/h
Pressure:             vacuum up to 5 barg
Currently max delta T for 8 stages 72 °C
 

Small High Speed MVRs

11 different types of small MVR fans have been designed for systems with lower steam capacities.  Ideal for TVR replacement, test plants or small process applications.
Applications:       1 to 8 stages
Volume:               50 kg up to 3 t/h
Pressure:             vacuum up to 1.49 bar
Delta T per stage 3-to max 8 °C average <5 °C
