Description
The Johnson Controls P29NC-38 Pressure Control Switch with Time Delay is an essentialpart needed to control the pressure in the HVAC systems. It operates through pressure variation and makes corrections to achieve the best conditions. The pressure on this switch is 100 PSI, and the capillary length of 3 feet to ensure that the system pressure is effectively controlled to optimize the operation in the process control. This is extensively applied in air conditioning and refrigeration systems. This results in preventing system damage as the protection comes in at pressure levels that are lethal to equipment. It has an in-built 120-second time delay which gives an added level of security while there is cycling throughout the operation.
