Amtrol- Therm-X-Trol ASME/Non-ASME

THERM-X-TROL^® Asme/Non-Asme
Thermal Expansion Absorbers

Designed, constructed, and tested per ASME section VIII, Division 1 standards.

Broadest line of sizes and models (37 models, ASME code and non code)
First to obtain ANSI/NSF61, IAPMO* & SBCCI*

The THERM-X-TROL is designed to provide control of maximum system pressures at a level below the relief valve setting. It also provides an additional space in the system to accommodate the increased volume of water created by thermal expansion, returning it to the system when hot water delivery is demanded. Maximum pressure is kept well below the relief valve setting by the THERM-X-TROL, with its pre-charged air cushion that is separated from system water. The relief valve does not open, therefore "spillage" is eliminated.

Closed Potable Hot Water System with THERM-X-TROL Expanded (heated) water is absorbed by THERM-X-TROL which means:

Water heater and fixtures are protected
Eliminates BTU and water waste, saving money and energy
No dangerous pressure build-up in the system
Relief valves will not be triggered
Potential safety hazard reduced
