YPS 280 Process Systems Controls

YPS 280 – Industrial Refrigeration Controls

Who this course is for
This course is designed for industrial refrigeration technicians, operators, engineers, and commissioning personnel who work with compressor control panels, system automation, and safety devices. It is applicable to both field service and plant operations roles.

Why this course matters
Modern industrial refrigeration systems rely heavily on automated controls to maintain stable suction pressure, manage refrigerant flow, protect compressors, and ensure safe operation. Poor control logic or improper tuning can lead to frequent trips, accelerated wear, high energy consumption, or unsafe conditions. This course explains how controls actually behave in refrigeration systems and how to interpret their responses.
