Johnson Controls High Pressure In 200PSI P100CP-161C

The Johnson Controls P100CP-161C is a high pressure control with an approximate 200 PSI setting.

A high pressure control protects the system against a rise in discharge pressure beyond safe limits. It opens the control circuit, stopping the compressor, when head pressure reaches its cut-out.

The protection matters because excessive head pressure has several destructive consequences. Compressor discharge temperature rises with head pressure, and elevated discharge temperature breaks down the oil, which then fails to lubricate. The compressor draws higher current, running hotter. And the system is operating well outside its design envelope, with pressures approaching the ratings of components and joints.

A high pressure control that trips is reporting a genuine condition, and the response should be to find the cause rather than to reset and walk away. The usual causes are a dirty or blocked condenser, a failed condenser fan, an overcharge, non-condensable gases in the system, or a restricted discharge path.

The 200 PSI setting suits systems operating with refrigerants whose normal condensing pressures are relatively low, and selection must be made against the specific refrigerant.

Applications include commercial refrigeration, air conditioning, and heat pump systems.
