Rheem-Ruud 42-102072-21 Dual Pressure Switch

The Rheem-Ruud 42-102072-21 Dual Pressure Switch is a essentialpart of the HVAC system, which is used to measure the pressure of the system. This pressure performance by detecting both high and low pressure conditions. It has a high working pressure of 0.15" of WC and a low working pressure of 0.3" WC thus providing optimum performance. It is mainly applied on residential and commercial refrigeration and air conditioning and heat pump applications. It works by causing the desired effects including turning on or off parts of a system when pressure levels are reached to help avoid harm to the equipment. This feature contributes to increasing the levels of security in operation of HVAC systems.
