A dual pressure control from Grainger helps to protect commercial refrigeration and air conditioning systems. Dual pressure controls combine high-pressure compressor protection with low-pressure cycling or safety functions. Some models offer a visible pressure scale and can be adjusted through the range without removing the cover. Manual reset models are trip-free. For R-12, R-22, R-134A and R-502 refrigerants, choose a dual pressure control from Grainger.
