Refrigerated Air Dryer

What is a refrigerated air dryer
Refrigerated air dryer is a device designed to remove moisture from compressed air systems by cooling the air to condense water vapor, which is then separated and drained. It is widely used in industrial applications to protect pneumatic tools and equipment from moisture-related damage.
SHANLI Advantages Of Refrigerated Air Dryer

Adopting a three-in-one aluminum finned heat exchanger, with low pressure drop, high heat transfer efficiency, and no secondary pollution in the compressed air system air duct.

Using a hot gas bypass valve (expansion valve): The equipment is equipped with a large cooling capacity hot gas bypass valve, with an energy regulation range of over 70%, ensuring normal operation of the equipment under unstable and low load conditions, which is larger than the energy regulation range of similar products (≤ 50%).

Adopting an electronic automatic drainage valve with a simple and unique structure, high efficiency, and long service life, it eliminates the blockage phenomenon of floating ball drainage valves, saves manpower and material resources, and effectively solves the problem of water accumulation in compressed air pipeline systems.

Hydrophilic aluminum foil+copper tube high-efficiency condenser
▲High heat conduction efficiency
▲Easy to clean (compared to plate fin type)
▲Strong adaptability
▲long service life
refrigerants
All refrigerants use R134A, R410A, and R407C environmentally friendly refrigerants, using refrigeration compressor brands like Danfoss, Bitzer, Panasonic, Copeland, Highly, etc.
Fan
The external rotor fan produced by the listed company is equipped with a 4-stage motor, which has low noise, large air volume, and far superior performance compared to internal rotor fans and hood-level fans.
copper tube
The refrigeration copper tube uses a well-known domestic brand, with a thickness 1-2 specifications thicker than the same industry, and the copper tube is subjected to corrosion resistance treatment, fully considering the service life of the copper tube.
Quality Management
High-quality domestic or international suppliers supply all products and components produced by the company. Quality control is in place at every stage from the entry of components to the delivery of products. Electronic small work orders are used for real-time quality tracking and traceability.
Refrigerated Air Dryer type
Refrigerated Air Dryer Working Principle
The content of water vapor in compressed air is determined by the temperature of compressed air: when the pressure of compressed air is constant, the higher the temperature, the higher the content of water vapor; The lower the temperature, the lower the water vapor content.
Lowering the temperature of the compressed air can reduce the water vapor content in the compressed air, and the excess water vapor will condense into a liquid, and then the liquid water will be removed, so that the compressed air can be dried. The cold drying machine works based on this principle.
Composition of refrigeration system: it is composed of four basic components: refrigeration compressor, condenser, expansion valve and evaporator. They are connected in turn by pipes to form a closed system in which the refrigerant circulates continuously
