GOTT-ECTFRAC-30 designed to demonstrate the principle of electronic controllers that are used air-conditioning and refrigeration especially for temperature control. The trainer features a panel mounted controller that has been specially developed for control systems in refrigeration and heat plants so that operation, setting and programming are optimized and simplified as much as possible.

It comes in a portable case complete with all diagrams instruction and accessories for operation. The controller is designed for defrost and room temperature control via pump down or compressor start-stop in refrigeration plants. The unit works on a bench top and includes facilities for operation of the controller such as mimic function diagram showing typical application and illuminated LED's to stimulate the operation of the refrigeration.
