Course Overview
Thetwo-day Basic Refrigeration Tech course is designed for maintenance craft workers from non-refrigeration backgrounds and other staff who want to gain a better understanding of the fundamentals of refrigeration technology. The course provides a simple understanding of the basics of refrigeration, some explanation of the terminology used and an appreciation of the range of applications.

Course Aim

To provide a good understanding of the principles of mechanical compression refrigeration systems, simple electric control circuits and the most common components employed. To introduce the fundamental concepts that must be understood by those who wish to advance in their knowledge and understanding of refrigeration technology.
