Johnson Controls P29NC-49 Pressure Control W/Time Delay M/R 20-100 PSI 120 Sec 36" Capillary 120-240V

The Johnson Controls P29NC-49 Manual Reset with Time Delay is a pressure control equipment that is well built for HVAC applications. It works at 100 PSI and has a time delay of 120 seconds. This control is operated by a 120/240V electrical supply and it can be applied in various uses. This is used in commercial and industrial climate control equipments including air compressors and refrigeration devices. It operates through the measurement of the system pressure and, upon occurrence of an overpressure condition, the mechanism is tripped to require a manual reset. This feature makes sure the system takes adequate time to achieve a balance before it starts working again, thus no short cycling or likely damage.
