Description
The Johnson Controls P70HA-3 Manual Reset Open Low-Pressure Control is a component of the HVAC used in the detection and control of low pressure in the systems to avoid potential problems. This control can be used to regulate pressure in air conditioning and refrigeration machines since it has a pressure range of up to 100 PSI and a strong 1/4″ FPT connection. It is suitable for use in temperature ranges of -40°F to 150°F and moves according to pressure to switch electrical contacts on or off. This action leads to the system allowing or denying the activity to avoid dangerous low pressure or reduced performance. They are widely applied on commercial refrigeration devices such as refrigerators, heat pumps, and air conditioners, for extending equipment life and enhancing efficiency.
