Overview of Air Source Heat Pump Dryer
1. Refrigerant (gas state) from evaporator comes to compressor, after compression, becomes high pressure & high temp gas, then comes to condenser;
2. In condenser, high temp. & pressure gas is condensed into low temp. & high pressure liquid state, huge heat will be released from this process. At the use of motor fans, such heat is transferred to hot air and sent to drying room. The hot air is circulating all around inside of drying room and making water in the objects released & vaporized, and after humidity exhaustion or dehumidification condensation, finally make the objects dry;
3. After that refrigerant becomes to high pressure & low temp liquid state, throttled by expansion valve, high pressure is reduced, then comes back to evaporator.
4. Refrigerant's temp suddenly reduces to be -20~-32oC once its pressure was released, in evaporator, it's fully heat-exchanged with outside air and absorb heat from the air. Then again to compressor and starts another cycle;
5. According to reverse Carnot theory, compressor is continuously running and cycling, transporting heat from the air, with 1 unit electricity to drive compressor, then retrieve 3-6 units heat for drying;
6. Heat pump dryer's running mode: drying (make temp. rise and humidity released), dehumidification (high/constant temp. dehumidifying), cool dry (Cooling and dehumidification).

The Details of Electric Heat Pump Dryer
The Advantages of Air Source Heat Pump Dryer
Compared to electrical, diesel and natural gas dryers, the best heat pump condenser dryer
are much more energy-saving, suitable for long-term investment; Considering running cost and environment protection, it is advisable to select RONRUI heat pump dryer as your drying solution!
1. Stable running, simple operation
Intelligent control and auto running without personnel duty after specification set finished.
2. Good Drying Quality
Low-temperature dehumidification drying, causes no loss of the objects to be dried, mildew or corruption can be effectively prevented.
3. Clean and health, without secondary pollution
Drying in a closed & sealed room, no pollution from outside objects.
4. Superior Energy Saving
Working in the wholly sealed drying room, no hot air and water vapor loses, ensuring a max. energy recovery.
5. Exact control of temperature and humidity
High precision sensors ensure a multi-point measurement, keeps running data reliably.
6. Advanced Concept: Closed-cycle dehydration technology
Dehumidification drying is adopted instead of traditional heat drying, nice drying effect can be achieved even based on drying at normal temperature.
7. Most of our products are open&close cycle dryers.
Completely avoids disadvantages of the open circle and close circle type dryer, and adopts advantages of them; This type dryer is not affected by ambient temp. & humidity, when temp. reaches the set degree, it will switch intelligently drying mode into open circle or close circle.
Sensitive heat or latent heat recovery system can effectively avoid low heating efficiency in low temp. ambient, even without electrical heater switched on, it can keep a fast temp. the rise in the dry room, and much more energy-saving.
A. Many parts of the products are produced by ourselves which could cut cost and make the prices competitive.
B. With many advanced testing equipments and professional quality inspectors, the quality of our products could be guaranteed.
C. We have professional designers and engineers, and OEM/ODM service is available for us!
