“SU” Models through 14″ and “WU” models through 10″ diameter are carried in stock for immediate shipment.

The “SU” Heat Exchanger is an instantaneous type, designed to heat liquids with steam. No space-wasting, expensive storage tank is needed.
Although the “SU” is used for heating many types of fluids, its widest application is for heating water. The “SU” can also be used as a converter for use with radiation, radiant panels and snow melting systems. Available in diameters 4″ through 30″.

Instantaneous water-to-water heat transfer — with pumped boiler water circulation. The “WU”, equipped with a B&G Booster Pump, pumps boiler water through the shell, thereby greatly increasing the capacity of the heater. Large volumes of hot water are produced by an amazingly small unit. Sizes range from 4″ diameter through 30″diameter.
