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.
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.
