FT22 Rising Film Evaporator


FT22 Rising Film Evaporator

The Armfield Rising Film Evaporator is a floor-standing unit, designed to provide practical training for the operation of large modern evaporator equipment in industry.


The single tube-in-jacket evaporator replicates industrial units which often contain scores of much longer tubes within the steam space. The component parts of the industrial process have been scaled down, feed tank, vapour/liquid separator, condenser, concentrate tank, condensate tank, CIP pump and vacuum pump, all manufactured from hygienic materials such as stainless steel, PTFE and glass.

The system is supported within a stainless steel framework and requires only a connection to suitable steam, electrical and water services for operation.

Only 0.65m² of floor space is required to install the evaporator and it has been designed to fit easily into a room of standard height.
