  • Surface treatment fieid: Heavy metal (nickel lead)concentrate, high-phosphorus wastewater.

APPLICATIONS
Based on the basic principle of the reverse Carnot cycle, the liquid refrigerant continuously cycles between gas and liquid phases within a closed loop system. During the phase changes, the working fluid releases and absorbs heat. The released heat is used to heat and evaporate the feed liquid, while the absorbed heat comes from the secondary steam generated by the evaporation of the feed liquid.
