Piller vapour compressors make a decisive contribution to lowering the power consumption and relieving the environment. Examples of areas in which it is used are: in the milk industry, the sugar industry, the saline industry, the cellulose industry and the seawater desalination and many more.

Vapour compressors - advanced and environmentally friendly

Piller supplies high quality fans throughout the world for mechanical vapour compression processes, which are specially adjusted to the needs of evaporator plant. This occurs in close cooperation with plant manufacturers, based on our development engineers' experience in the process engineering industry.

Special characteristics:

     » Vacuum-proof housing design, up to 0.1 bar (abs.)
     » Rotors for extremely high circumferential speeds for increasing the efficiencies
     » Water jets for cleaning the rotors and for temperature recooling during operation
     » Low-wear labyrinth seals
     » Optional connection in series or parallel possible for larger pressure differences or
        volumetric flows
     » Patented compression oil vaporisation both for rolling bearings as well as for plain friction 
        bearings enable design speeds well above the critical bearing speed and low vibration
        operation even during speed adjustment

Piller has developed a new type of fan to series production stage, the rapid rotor MXGAE for smaller mass flow rates, primarily in wastewater treatment evaporators. Driven by a motor also developed by Piller, this machine runs with a speed of over 12,500 rpm. Thus, it is possible to use a centrifugal fan, even for small mass flow rates, to achieve temperature increases of up to 6.0 °C.
