Manufacturer Description

Amtrol invented the thermal expansion tank to help control pressure in a closed, potable, hot water system. This eliminates pressure relief valve discharge, saves energy and helps protect expensive hot water heaters.

Recently, Amtrol added a number of new features to the Therm-X-Trol including:

• 50 psi precharge – the industry's highest.
• Fresh Water Turbulator™ – patent pending water diffuser.
• Antimicrobial liner – neutralizes bacteria on contact.

These features, along with all of the other things that set Therm-X-Trol apart from the competition, make it the standard of the industry. Plus, Therm-X-Trol is Made in the USA, unlike virtually all other thermal expansion tanks on the market.
