Detailed Information

Description

Expansion vessel for heating, recovery and cooling systems.

Expansion Vessels must be installed according to instructions in VVA 93. The expansion vessel is inspected visually prior to installation. When installing with a system, the pre-pressure must be adjusted so that it matches the static pressure prevailing at the tank’s connection point. The adjustment takes place without the influence of system pressure (depressurised on the system side).

The expansion vessel does not require maintenance. Air valve must be provided with protective covering.
