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.
