Vapor compression evaporators are becoming increasingly popular due to higher energy costs. The process vapors generated in these evaporators are compressed with a centrifugal, rotary, or thermo compressor or high-speed fan. Compression of the process vapor raises the saturation temperature and this product becomes the heating medium for the system. High heat transfer coefficients and minimal entrainment make Rosenblad Design Group's evaporators especially suitable for this cycle.

Other advantages of RDG's vapor compression evaporators are as follows.

• All the evaporation takes place at one temperature and requirements.

• Hot process condensate is available for on-stream washing of surfaces.

• Any excess heat will be at the highest temperature in the system.
