VNT SERIES Heat pump vacuum evaporators Minimization of energy consumption using the heat pump principle in a vacuum environment. With the absolute pressure in the boiling chamber equal to ≈ 33 mbar, evaporation is carried out at very low temperatures (≈ 35 ºC). Volumes processed 100 – 30,000 liters/d. V-NT SERIES WITH DOUBLE BOILING CHAMBER Heat pump vacuum evaporators with double boiling chamber The refrigeration plant is divided into two boiling chambers: the high pressure side is used to bring the product to boiling point in the first stage, while the low pressure side is used to re-condense the steam produced in the second stage. The result is an energy saving of 45%.
