Operation and Maintenance of Refrigeration for Technicians

The goal of this three-day Refrigeration course is to provide a broad introduction to air conditioning and refrigeration systems, including everyday operation and important refrigerant safety practices. Participants are taught common practices and some "tricks-of-the-trade" for general operation and maintenance of their Refrigeration systems. They will learn about maintenance schedules and servicing, system diagnostics, troubleshooting, and fine-tuning to gain maximum efficiency. The course also covers an introduction to commercial and industrial chillers, regulatory laws and energy conservation. Overall, we will help you get the maximum life out of your Refrigeration systems while keeping it up and running as efficiently and consistently as possible
