Flexcon BUF-40 ARGOSY™ Series Hydronic Buffer Tank, 1-1/4 in Connection, 40 gal Tank, 21 in Dia

The ARGOSY™ Buffer Tank by Flexcon is the only pressurized composite buffer tank on the market. ARGOSY™ 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 deg F at 75 psi and 140 deg F at 100 psi, our NSF approved polypropylene core wrapped in a blend of continuous strand fiberglass and a high temperature resin makes the ARGOSY™ Buffer tank perfect for hydronic and geothermal heating and cooling, low mass boiler systems and chilled water applications. ARGOSY™ 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 deg/hr. Tanks are available in sizes of 22, 40, 55, 80, and 120 gal and all come with 4 side ports, a thermal well (40 to 119 gal), vent, vacuum breaker and drain.
