WITT refrigerant pumps are specially designed to deliver primary refrigerant liquids at their boiling points. For several decades they have demonstrated their capability in industrial refrigeration plants throughout the world, working with ammonia (NH3) and other refrigerants. WITT refrigerant pumps are characterized by their proven ability to pump liquid/vapour mixtures. This is of particular importance as the evaporation temperature decreases.
