Sanitary Heat Exchanger (MHE)



MHE - Laboratory Sample Condenser

The MHE (Miniature Heat Exchanger) Double Tube and Shell heat exchanger have been designed to
allow Clean Steam (CS) and Water for Injection (WFI) samples to be taken quickly and easily whilst
maintaining a sterile testing environment.

MHE - is ideal to be mounted at the sampling point and can be operated with either mains or chilled water
as the cooling medium availability of aseptic/sterile sample valve allow fine control of sample flow during
testing

The MHE can be sterilized in situ-on-line, thus ensuring continuity of samples regardless of testing frequency,
ideal for fluids in pharmaceutical/Biotech or any type of high purity systems applications.
