Zilmet 21.1 Gal Solar Plus Tank 1" NPT Connection
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 the ZILAN membrane, that can withstand temperature of 212°F. ZILAN is a 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.
