Principles of cold production
In addition to the conventional compression refrigeration system, we offer other methods of cold production (refrigeration).
ET 101
Simple compression refrigeration circuit
Cooling and heating of the heat exchangers directly tangible.
ET 352
Vapour jet compressor in refrigeration
Cold production using thermal energy. Transparent condenser and evaporator allow the view into the inner workings.
