ET 910.10

Set of Training Panels

Technical Description

ET 910.10 consists of 11 different training panels that can be mounted modularly on the basic unit ET 910. With the aid of the required accessories included in ET 910.12, the training panels and the basic unit can be combined to various refrigerant cycles. Typical components of a refrigeration system can be investigated. The set comprises simple refrigerant components as filter, flow meter and pressure gauges, as well as control respectively expansion valves. The superheater included in ET 910.10 is a heat exchanger where the refrigerant is evaporated completely before entering the compressor while the liquid refrigerant is supercooled before the expansion respectively control valve.
