PSC Mini Pressure Controls

The PSC Mini Pressure Control provides the ultimate in reliability and flexibility in a commercial grade mini pressure control.

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.
