This Ohio company recently expanded its Certified Parts line to include the CP1, CP2 and CP3, commercial pressure controls that the company says are designed to offer contractors greater convenience and flexibility during compressor installation and service. Some of the features on select models include: a standard single pole, double throw switch; captive clamp-type screws and a slanted ground terminal screw. These controls make it easy to override the units when necessary and protect against refrigerant leaks.
