ControlTrends Training: High Pressure Refrigeration Controls

A special thanks to Mike Glenn from Johnson Controls for putting this training video on High Pressure Refrigeration controls together. You can also check out Mike’s video on low pressure refrigeration controls by clicking here.

These switches regulate critical functions within a refrigeration system and are essential to its proper operation. Low-pressure switches are commonly used to control compressor operation or act as a low-limit control.

High-pressure controls sense compressor discharge pressure and can stop the compressor in case of excessively high pressures. Dual-pressure controls are comprised of low pressure and high-pressure controls mounted in a single housing, with a single switch operated by either control. Other functions of mechanical pressure switches include condenser fan cycling and oil pressure safety control.

  1. “Mike Glenn, from Johnson Controls shows us how the T600 can be used to control and save energy in portable classrooms. The T600 is a low cost practical way to control temperature and reduce energy consumption in your remote classrooms.”

    As seen from you other post about him. A great guy who knows how to utilize efficiently.
