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.
