VARICOMP® Expansion Compensators are used to compensate for thermal stress in pipe systems resulting from thermal expansion. They are especially suitable for valve matrices and fixed process pipe systems. They are ideally suited to hygienic and aseptic process operations. Applications include the dairy, beverage and food industries as well as the pharmaceutical, fine chemical, biotechnological and cosmetic industries. They can also be used as an alternative for Ω-elbows.

The Compensation Element
The compensation element is the main element of the compensator. It absorbs the stress and compensates it.

Technical Features of the Compensation Element
  • Compression molded compensation element made of elastomer (EPDM and FKM available)
  • Integral vulcanized support rings of stainless steel, used against pressure loads (overpressure and vacuum)
  • Integral vulcanized support ring of stainless steel used for fixating the compensation element
  • Smooth inside surface
