The Arctic Hybrid Buffer Tank is the only pressurized composite buffer tank on the market. Better insulated than steel buffer tanks, roughly half the weight, and it will not rust!
Arctic Buffer Tanks will never corrode and are half the weight of steel buffer tanks. These advantages can reduce labor costs on installations while being a cost-effective way to improve system efficiency by reducing heat pump short cycling during low load periods and hydraulically separating the source from the distribution system. Rated to 180 degrees F at 75 PSI and 140 degrees F at 100 PSI, our NSF approved polypropylene core wrapped in a blend of continuous strand fiberglass and a high temperature resin makes the Arctic Buffer tank perfect for hydronic heating and cooling, low mass boiler systems and chilled water applications. Arctic tanks are insulated with a closed cell foam that provides a R-value that is unmatched by the competition and has a heat loss of less than 1 degree/hour. Tanks are available in sizes of 22, 40, 55, 80, 120 gallons and all come with 4 stainless steel side ports, a thermal well (except 22 gallon), vent, vacuum breaker and drain.
Operation:
The primary application of a buffer tank is to reduce heat pump, chiller, or boiler short cycling. Hydronic buffer tanks are used in systems operating below the design load condition, which is most of the time, or in systems having several low BTU cooling or heating loads calling at different times. The buffer tank is an energy battery that stores heated or chilled water for use when needed. By using a 4-port design the supply and demand are hydraulically separated so that the heat pumps high flow circulating pump is separated from the hydraulic loads circulating pump.
What It does:
The buffer tanks are built with 4 stainless steel connections. Two connections can be piped to the heat pump or boiler, and two connections can be piped to the distribution system. When piped correctly the tank serves as both a thermal buffer and a hydraulic separator.
Highest Efficiency:
No other buffer tank matches the Arctic Hybrid Tank in terms of heat loss efficiency. With a heat loss of 41% than the next comparable buffer tank, the Artic Hybrid Tank outperforms and save money and will never rust out!
