ASME DHW Storage Tanks, 80-175 Gallon

Storage tanks are required in conjunction with WH water heaters. The heater provides rapid heating of a small volume of water; the tank provides a storage medium with enough capacity to handle short-term loads. This separation of functions provides extremely fast, flexible recovery.

Under ASME section IV part HLW rules, an ASME-compliant tank is required when the total system volume exceeds 120 gallons, or when the total heating capacity exceeds 200,000 BTUH.

When properly selected and installed, these tanks can provide 80% draw without appreciable temperature decrease in a single-temperature application.

Features:

Available in 80, 115 and 175-gallon sizes.
150 PSIG maximum working pressure

Two magnesium anodes included
Glass-lined steel jacketed
Insulated with rigid foam to R12.9, meets ASHRAE 90.1
2 NPT connections for heater piping and tank outlet
Ports for T&P valve, tankstat, thermometer, and drain valve

規格

The tank can be installed whenever the demand requires stored water of 80 to 175 gallons. Whether installed individually or as several tanks in parallel, this tank can provide 80% draw without an appreciable temperature decrease in single-temperature applications.
