PSC Mini Pressure Control
The PSC Mini Pressure Control provides the ultimate in reliability
and flexibility in a commercial grade mini pressure control. A
standard plug connectable design simplifies installation and
service. The SPDT switch allows the addition of alarm circuits
on high or low pressure applications. Models with high tempera-
ture bellows and built-in pressure pulsation snubbers make the
PSC ideally suited for compressor head mounting high pressure
limit control applications—automatic or manual reset versions
are available.
Pressure Ranges/Differential also make the PSC controls ideally
suited for condenser fan cycling applications. Low Pressure
versions with standard or narrow differential switches make
these controls ideally suited low pressure limit or back-up safety
controls on electronically controlled systems. Numerous options,
such as panel mount or capillary connections are available on
high volume applications. Standard on all models are worldwide
agency approvals.
