DESCRIPTION

The Bell & Gossett’s PSH is a device which makes the primary

and secondary circuits connected to it independent and can

be used on hot or chilled water systems.

The PSH is supplied with an air-vent and check valve assem-

bly to permit automatic discharge of the air in the circuits. The

PSH is also equipped with a drain valve for removing any

impurities deposited in the bottom of the unit.

The PSH should be sized according to the maximum flow rate

at the inlet. The selected value must be either that of the pri-

mary circuit or of the secondary, whichever is the greatest.
