Johnson Controls P70CA-4 Pressure Control Switch Open-High Ammonia 100 PSI 20" Capillary

The Johnson Controls P70CA-4 Switch is another essentialpart used in detecting high pressure in ammonia refrigerant-based HVAC systems. This unit acts as an open-high-pressure switch that checks the pressure above 100 PSI for the right operation of the system. This switch is useful in protecting equipment and attaining the best working conditions in industrial refrigerators and ammonia based air conditioning systems. It regulates pressure and does not damage the system through high pressure. This switch is primarily used in commercial refrigerator systems, cold storage, and industrial HVAC and it is used to indicate high pressure conditions making the system safer and more reliable.
