Series WSC and WSS are water make-up supply units. Both units include a positive air-gap to eliminate the likelihood of backflow and possible contamination of city water supply. These units supply a detached, central, make-up sup- ply reservoir for de-aerators, boiler feed units, process loads, cooling systems and towers.

The WSC unit has a cast iron receiver. The WSS has a fabricated steel receiver. A float switch operated solenoid make-up valve supplies water to the receiver through the air gap fitting. Available in either simplex or duplex configuration with Centriflo® pumps.
