COMPENSATION SACK

The difference of pressure between a chamber and a surrounding are the result of atmospheric pressure’s changes, as well as the temperature’s changes inside of the chamber (e.g. while cooling).
Compensation sack reduces pressure’s changes in a chamber and in that way restricts compensation valve’s operation, meaning a gas exchange between a chamber and a surrounding.
Typical size of a compensation sack: 3m3.
It is made of a special, durable multilayer foil.
Terminal’s diameter: 90mm or 110mm.
