VIMATHERM 's HVAC heat exchanger is a gasketed plate heat exchanger which can be dismantled. A plate pack, usually made of Stainless Steel, is placed between two very thick carbon steel end plates and pressed by several tie rods to obtain its watertightness.

VIMATHERM 's HVAC heat exchanger consists of:

 

 

  1. one plate pack,
  2. one fixed head used as front support,
  3. one mobile head,
  4. two guide bars,
  5. one end post,
  6. one set of tie rods allowing to tighten the plate pack.

Depending on the working data, the four connections can be either all four on the fixed head or two on the fixed head and two on the movable pressure plate.
