Heat Exchanger
  
Design: 
Plate heat exchanger, bolted, thermal lenght dependent on case of operation,
consisting of a fixed connection plate as well as a removable pressure plate,
which is pressing a plate package by means of clamping bolts.
All plates provided with gaskets. Gasket material to be chosen according to kind of medium.
A double gasket with outer leakage groove in the connection area prevents mixing of media.
  
Units are fabricated acc. to quality standard DIN EN ISO 9001.
