Oil Protection Controls

Oil protection controls are used to shield refrigeration compressors against shutdowns due to low oil pressure. As with HVACR relays, if the oil pressure in these refrigeration units breaks down, the internal pneumatic controls will stop the compressor after a predetermined amount of time has elapsed. A differential pressure switch will activate itself when a positive or negative change in pressure triggers previously programmed oil pressure parameters. Speaking of oil, a great way to move oil drums from place to place easily is with a drum dolly. These heavy-duty dollies have a caster-style wheelbase which makes oil drums much easier to move. Zoro also carries water level controls and accessories, duct pressure switches, and building automation controls.
