Refrigerated Compressed Air Dryer
Request a Quote
Refrigerated compressed air dryers are designed with a highly efficient refrigerant compressor and refrigerant accessories. With a pressure drop in the airflow channel at less than 0.02Mpa, the working efficiency is improved and electricity usage is reduced.
Working condition- Inlet temperature Lower than 70℃ (high temperature); lower than 45℃ (low temperature)
- Working pressure 6~10kg/cm²
- Maximum pressure 1.0Mpa, 10kg/cm² (customized pressure is available)
- Environment temperature 2~50℃
- Refrigerant R22 (R407c, R134a customized refrigerant is provided)
- Dew point temperature 2~10℃ (when air pressure is 7kg/cm²)
- Refrigerated compressed air dryers use a high quality thermal expansion valve, which is able to automatically adjust refrigerant supply according to the dryer's actual load, making the air compressor more energy saving and energy efficient.
- This air dryer is designed with a superior electronic drain valve, which, after being set, can discharge the moisture accumulated in the compressed air in time, ensuring the dryness of the compressed air.
- The heat exchanger in the refrigerant compressed air dryer uses an 8mm thick copper pipe, ensuring the heat exchanger remains crack free.
- The filter in the air dryer features a small volume and large filtration area, which can filter moisture and impurities in the cooling system, making the air dryer cleaner and less prone to failure frequencies.
- The refrigerant compressed air dryer is able to automatically detect low oil pressures in the semi-hermetic compressor to make it more reliable and safe.

- In the specification chart, "G" stands for "screw threaded connection", while the "DN" stands for "nominal diameter of flange connection".
- There should be no less than 1m space left around the dryer unit for ventilation and maintenance. The dryer unit can be easily installed without the base.
- The stop valve must be installed in the dryer unit inlet and outlet. A bypass valve should also be mounted in the unit under the condition that the air displacement is not interrupted. This makes it easier to repair and maintain the equipment.
- If the model, parameters, specifications and colors of the air dryer changes, please refer to the machine for actual data.
- The rated air handling capacity should be adjusted when the working temperature and pressure exceeds the specified requirements.
- Atlas Greenair is able to provide customized air dryers with various specifications.
