The device allows to supply with hot and cold water the hydraulic test benches for laboratory, production and endurance applications.

The TCW/CCW generators are made up of two independent plants used to produce and store hot and cold water and recovery the return mixed water. The refrigeration circuit uses a silenced airtight SCROLL type compressor that allows a high power efficiency, lower electric consumption and lower noise. SCROOL compressor reduces the risk of valves failure, high frequency failure in other compressor type. The cooling plant consist in a forced air condenser with fans controlled by inverter, an external tank heat exchanger, an air-mixing pump and an expansion device with thermostatic valve with by-pass on hot gas. The heating plant consists of three heating elements and one water circulator. The TCW/CCW group works with closed circuit. The water used on the bench is recovered and sent again to the generator where it is heated/cooled again at the temperatures required for the test.
