ACCESSORIES PSH - Primary/Secondary Header
Description
The B&G low-loss header, Model PSH, is a
combination air separator and manifold that
creates independent primary and secondary
circuits. The B&G Model PSH is equipped
with a purge valve allowing the user to
remove any debris deposited on the bottom
of the vessel and an air vent releasing
trapped air in the system. The insulation,
which is provided as standard, prevents
water vapors entering from the outside and
eliminates the formation of condensate on
the PSH body.
