21.5m³/min Explosion-proof Commercial Air Compressor Dryer Refrigeration System

We are top quality manufacturer of commercial air compressor dryer. Besides, we can customize many good price air dryer refrigeration system. For example, this one is the explosion proof refrigerated air dryer. It’s suitable for flammable and explosive environments. The explosion-proof grade is EXDIIBT4. This refrigerant air dryer has wide application in special gases, such as hydrogen, biogas, oil and gas, coal gas, natural gas, etc.

Commercial air compressor dryer utilizes a refrigeration system. Firstly, it cool the compressed air to a certain temperature. Afterwards, extract the moisture inside. Finally exhaust the water through the drain valve. So it reaches the drying dew point. But the traditional refrigerant dryer does not have explosion-proof function. If there is propane gas, ethylene gas, and hydrogen gas, the dryer will not work properly.

(3) Excellent control system
Fully automatic adjustment and control. So it’s stable and reliable. Besides, it’s easier to control. Additionally, we provide a variety of customization. PLC and RS485/RS232 communication is available. This enables remote control.

(4) High-quality refrigeration components
Our refrigerated air dryer has a hot gas bypass valve and filter dryer. It’s also with high and low voltage protection. So it ensures that the air dryer refrigeration system is stable.

How does refrigerant air dryer refrigeration system work?

Structurally, in addition to the regular refrigeration system, it also includes explosion-proof devices. That is, explosion-proof control electric box, fan and refrigerant compressor, etc.

(1) Drying system of commercial air compressor dryer

Rotary scrwe compressor discharges compressed air. They are high temperature and high pressure gases. Besides, the moisture content is also high. Firstly, they flow to the pre-cooler. It will exchange heat with the returning drying low temperature air. So their temperature will drop. At the same time, some condensed liquid will be form.

Afterwards, they flow into the evaporator of air dryer refrigeration system. These air will be cooled to 2-10°C by the low temp. refrigerant liquid. It will condense the water vapor inside into liquid water. Next, the dry compressed air and water enter the air-liquid separator together. The device separates compressed air and liquid. Among them, the liquid flows to the electronic drain. Here, we use explosion-proof control electric box to control the electronic drain. Then drain the liquid. Finally, the low temperature dry compressed air return to the precooler. After the temperature rises, it is discharged from the outlet.

(2) Cooling system of refrigeration air compressor dryer

Explosion-proof refrigerant compressor sucks refrigerant vapor. After compression, it exhaust the refrigerant gas. At this time, they are high temperature and pressure. Afterwards, the refrigerant gas enters the condenser. After cooling, they become the liquid refrigerant. Next, they flow into the expansion device. After throttling, it forms low temperature and low pressure refrigerant.

Then enter the evaporator of the dryer. They exchange heat with compressed air. It can reduce their temperature. Here, the liquid refrigerant becomes the gaseous state due to heat absorption. Finally it is sucked in again for compression. Therefore, it achieves the purpose of circulating refrigeration.

The function of explosion-proof electric box is to control the compressor. When the compressor is working, the condenser will release a lot of heat. As a result, the ambient temperature will be too high. But explosion-proof fans can speed up air flow. So as to achieve the purpose of heat dissipation.
