expansion vessels for heating and solar

expansion vessels for heating and solar
Description
CAL-PRO are membrane expansion tanks for centralized closed circuits suited to absorb the increased water volume when the temperature in the heating system increases. Produced with an SBR membrane and according to PED norm 2014/68/EU for centralized non potable water heating systems.
SOLAR-PLUS: in the solar circuit, the particularly high temperature requires heat relief. The solar liquid reaches temperatures higher than 392°F. evaporates and can reach the solar station damaging essential parts such as pumps, fittings, gaskets and above all the tank membrane. For SOLAR-PLUS expansion vessels Zilmet has developed ZILAN membrane, that can withstand temperature of 212°F. ZILAN is an high temperature membrane made of synthetic rubber, product of decades of experience in installing Zilmet expansion vessels in solar collector systems. ZILAN synthetic rubber membrane is specifically designed for SOLAR-PLUS expansion vessels.
