1 Commercial Thermal Expansion s For Closed Thermal Water s

2 mtrol thermal expansion tanks are engineered to control pressure build-up in closed, potable water systems. vailable in diaphragm, full acceptance and partial acceptance bladder designs, all Therm-X-Trol expansion tanks are made in the US at our ISO 900 : 2008 registered facilities. SME tanks meet Section VIII, Division Standards. Features ccepts expanded water caused by thermal expansion. Returns water to the system when hot water is used. Protects water heater and fixtures. Eliminates wasted energy and water. Prevents dangerous pressure build-up. Eliminates a potential safety hazard. Typical Installations In-Line s FP, Check or PRV CWS Hot Water Diaphragm s Heavy duty butyl diaphragm; industry's thickest. Fixed diaphragm construction for leak-free performance. THERM-X-TROL Expansion Water T & P Valve ladder s Heavy duty butyl bladder; industry's thickest. Replaceable full and partial acceptance designs. Stand s FP, Check or PRV CWS Hot Water THERM-X-TROL Expansion T & P Valve ST-80VC -50 SGR Water ST-80VC 50 PSI Rating with Sight Glass & Restraints

Line Pressure at Expansion... PSIG Selection of Expansion : 6. Find and enter Water Expansion Factor (see Table ) 7. cceptance = Line () x Line (6)... gallons 8. Find and enter Design Pressure Factor (DPF)... (see Table 2) 9. Minimum = Line (7) x Line (8)... gallons 0. Select an SME or non-sme THERM-X-TROL Expansion that is at least equal to Line (9) for (gallons) and Line (7) for cceptance (gallons). Multiple tanks may be required. Maximum Temp.
