HPE's low-temperature vacuum evaporators, based on a unique heat exchanger design, integrate heat pump and vacuum technology. Originating from Italian craftsmanship, they are integrated using skid-mounted modules and achieve evaporation temperatures as low as 40°C. They provide customers with solutions for high-concentration waste liquid concentration and volume reduction (5-15% concentrate), crystallization separation, and zero emissions, thereby reducing costs and providing value-added services.
