Care’s concentrators are based upon the application of vacuum technology in combination with heat pump system.

The system consists of a reactor with two heat exchangers; one to heat waste liquid (boiling chamber) and the other to condense the evaporated product (condensation chamber). The reactor is vacuumised by the application of a liquid-ring vacuum pump, which first exhausts the air inside the unit and then the condensed product.

The heat pump circuit is driven by a compressor, which compresses the refrigerant gas in the heat exchanger, causing the liquid to boil and consequently evaporate.

The gas leaving the heat exchanger goes through the sub-cooler and then vaporises, by an expansion valve, into the condensation chamber coil. The freon absorbs heat making possible the steam condensation.
