Integral design, embedded installation, built-in heat recovery device, 
simple installation, significant energy saving.


●Ehanced vapor injection compressor for heat pumps
Compressors being the core part of heat pump dryer, we select and use enhanced vapor

injection compressors specially for heat pump, whch can ensure normal operation of the unit

under the temperature of 10℃ below zero, and a high-efficient and strong heating power. Thus,

the problem that previous heat pump dryers' efficiency greatly declines in low temperature

environment is solved. 
●High Efficient heat exchanger
The combination of Hydrophilic aluminum foil corrugated fins and high efficient internal thread

heat-transferring copper pipe makes process of defrosting and draining swift, and ensures

efficient heat-exchange. The selected aluminium alloy end plate is resilient and corrosion-

●Electric expansion valve
Selecting industry-leading impulse type electric expansion valve and pressure sensors can

ensure a quick reaction, an accurate adjustment, a wide application arrange(high or low

temperature) of the unit, improving energy efficiency ratio.
●Intelligent control
The intelligent control mainboard of the unit, with muti-functions, such as operational control and

safety protection, has faster processing speed, higher sensitivity, better ability of anti-interference,

keeping the unit operating steadily under bad conditions.
●Efficient heat recycle
Intergral heat pump dryer integrates with heat recycle equipment, so that a great deal of waste

heat released when can be recycled, with a rate of more than 60%.
The module combination of the units makes the design of drying-chambers and the match of

units’ number more flexible. The number of modules is intelligently controlled according to load

change, so that the whole unit can operate with a low energy consumption and long service life.
