Amtrol, Therm-X-Trol, Extrol and Well-X-Trol Expansion/ Pressure Tanks and Air Separators 


Therm-X-Trol  Water Heater expansion tank helps to absorb expanded water in closed, hot water systems and protect the water heater.  Thermal Expansion tanks are  engineered to control pressure build-up in closed potable water systems.  They are available in diaphragm full acceptance and partial acceptance bladder designs.

Well-X-Trol Pressure Tanks can help store water to increase your available water on demand and increase pump longevity by minimizing rapid pump start & stops.

Amtrol Air Separators are designed to remove entrained air from circulating water or anti-freeze in a closed non-potable water system.
