LOW TEMPERATURE VACUUM HEAT PUMP EVAPORATORR

Vacuum heat pump evaporator uses heat pump technology to provide energy for evaporation. Vacuum heat pump evaporator uses vacuum pump to keep the system in a high vacuum state(<5000pa), so that the temperature of the material liquid boiling is reduced to between 35-45 ℃, thereby increasing the heat transfer efficiency and evaporation effect; The water treatment capacity of vacuum heat pump evaporator is between 30-2000 kg/hour.

Working Principle of Heat Pump Evaporation

Vacuum heat pump evaporator uses vacuum pump to keep the system in a high vacuum state(<5000pa), so that the temperature of the material liquid boiling is reduced to between 35-45 ℃, thereby increasing the heat transfer efficiency and evaporation effect;
Vacuum heat pump evaporator uses heat pump technology to provide energy for evaporation. Its energy consumption is only used to drive the compressor to run, which greatly saves energy consumption and achieves more than 90% energy saving

Working principle of Heat Pump Evaporation

Plug and play, no additional steam and cooling water is required.;
Compared with traditional evaporation technology, heat pump evaporation technology can save more than 90% in energy consumption;
Ultra-low temperature evaporation. The vacuum degree is above -0.095Mpa, the evaporation temperature is 35-45 ℃. More suitable for heat-sensitive effluent. For corrosive effluent, the degree of corrosion of the equipment is minimized, and the life of the equipment is greatly extended compared to traditional evaporators;
Modular design. The structure of the equipment is more compact, the area is small, and the assembly operation is fast and convenient;
Fully automatic control, one-key start, automatic feed, automatic discharge, material break alarm;
Low failure rate, stable operation, extremely low repair and maintenance costs.

The heat pump low temperature (LTE) evaporator does not rely on fresh steam and requires only electric- ity and a small amount of cooling water to operate, and the scroll compressor LTE evaporator even re- quires only electricity. It can effectively solve the problems of high evaporation volume and low energy efficiency of conventional evaporator, and reduce expenses for small and medium-sized enterprises.

The LTE evaporator also maintains a very low temperature during the evaporation process and can effectively handle all kinds of heat-sensitive materials.
