APOLLO Stainless Buffer Tank - 175/250gal

APOLLO Series - Buffer Tank

The APOLLO BF series tanks are an essential component for properly operating the hydronic heat pump system. When very low or no-load conditions occur, the buffer provides time for the heat pump to react and shut down correctly without spiking temperature. In winter, it also helps defrost the cycle.

The insulation prevents condensation and heat loss. These tanks are designed with everlasting corrosion resistance and come equipped with a sensor well.

The APOLLO BF series buffer tanks are essential for hydronic heat pump systems, ensuring smooth operation during low or no-load conditions and aiding in defrost cycles during winter. Made with a durable SS316 inner tank and insulated with 2" polyurethane foam (1 1/2" for the BF250 model), they minimize heat loss and prevent condensation. The outer jacket is constructed from painted galvanized steel, providing additional durability.

Available without coil or with 2 internal coils, these tanks offer flexibility for various system needs. Features include a sensor well, drain valve, pre-installed plugs on all additional connections (except the 2 main ports), and a 3/4" Relief Valve CSA/UL rated at 125psi, 210°F. The tanks are designed with NPT female connections for easy integration into your system.
