Therm-Plus Thermal Expansion Tank
Thermal expansion occurs as domestic water is heated. Therm-Plus expansion tanks are designed to safely maintain water pressure levels in water heating systems to avoid the relief valve discharge and other potentially hazardous conditions. Thermal expansion tanks work in conjunction with a backflow preventer or check valve. AQUASKY expansion tanks are built with a stainless steel system connection with patented Leak safe technology. Inside each tank is a heavy-duty, butyl rubber diaphragm with a 400% elongation physical property. A polypropylene liner separates the water from the pre-charged air chamber. The tank controls excessive pressure generated inside the water heater using a sealed compressible air cushion space to store and hold the addition expansion water volume.
