THERM-X-TROL ASME ST-5C-DD Expansion Tank

THERM-X-TROL ASME FEATURES

• #1 choice of Professional Installers in USA
• Safest and most cost effective way to control Thermal Expansion
• Easy to install
• The Innovator of Thermal Expansion Control in Closed Potable Hot Water Systems
• Recognized Industry Leader in Quality, Design, Manufacturing, Delivery and Service
• Designed, constructed, and tested per ASME section VIII, Division 1 standards

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
