  • Description

    Heat pump device consists of compressor, electronic expansion valve, dry filter, four-way valve, evaporator, casing condenser, fan and other major components, it adopts inverse Carnot principle, the compressor from the evaporator inhalation of low temperature and low pressure air Refrigerant, through the work of the refrigerant compressed into high temperature and high pressure air, high temperature and high pressure air into the condenser and air exchange heat, condensed into a cryogenic liquid in the condenser and release a lot of heat, the material absorbs its release of energy through the hot air circulation strong row of its moisture to achieve the purpose of drying materials. The condensed high temperature and low pressure liquid is throttled and reduced by the expansion valve, and the heat of the surrounding air is absorbed by the action of the fan in the evaporator to volatilize into the low pressure air and is compressed into the compressor, so that it is circulated continuously and dry materials continuously.

    1.This product is mainly applicable to the drying of agricultural by-products with large moisture, long drying cycle and special dehumidification requirements.

    2.Human-machine interface operation, PLC control, temperature and humidity control, intelligent dehumidification, running state display, fault detection, etc,.

    3.Adopts independent research and development of multiple dehumidification heat recovery technology, heating speedy, dehumidification efficiency, heat recovery, energy saving effect is remarkable;

    4.Whole machine with closed loop circulation, can not be influenced by the open air temperature, heat loss is very small, not only energy saving, but also used widely.

    5.Hot air circulation adopts our patented technology, two-ways circulation, heat  multi-times reuse, drying efficiency is high, uniformity is good.

    6.Equipment selection industry is optimal, running stable, long service life.

    7.Layout according to the workshop situation, beautiful, generous, easy to clean.
