China GA-HFB Air Dryer - Reliable Suppliers and Factory for Efficient Refrigerated Compressed Air Solutions
Functional Characteristics
The refrigerating dryer uses the low temperature of the evaporator of the refrigerating system, let's lower the temperature of the compressed air, and then condense the water out, to obtain a dry compressed air source; but cooling the compressed air doesn't necessarily mean the water will be expelled, because a lot of condensed water will be taken away from the refrigerated dryer due to the rapid flow of compressed air, resulting in the phenomenon of excessive water content at the service end.
GA series air-cooled refrigerating dryer is a new machine developed to solve this problem. The main feature is that the horizontal evaporator is designed with an upright differential configuration. At the bottom of the evaporator is equipped with a refrigerant high-pressure secondary condensation device, this careful design not only makes the cooling system load more stable, the principle of gravity is also used to make the condensed water more difficult to be carried away from the evaporator by the fast-moving compressed air due to the relationship between gravity, so that the condensed water can be completely discharged.
Correct method of selecting a cold dryer:
Under different working conditions, the air volume of all kinds of cold drying machines will be different. To choose a suitable cold drying machine, five factors must be considered:
- The flow rate of compressed air
- Working pressure
- Inlet temperature
- Ambient temperature
- Required pressure dew point
Selection Example:
The nameplate of the air compressor indicates that the exhaust volume is 5.2m³/min, the exhaust pressure is 0.8MPa, the maximum exhaust temperature is 50℃, the ambient temperature of the machine room is 38℃, and the target pressure dew point is 10℃.
Selected Model: GA-50HFB
Frequently Asked Questions (FAQ)
How does a refrigerating dryer obtain dry compressed air?
It uses the low temperature of the refrigeration system's evaporator to lower the temperature of the compressed air, which condenses the moisture out of the air flow.
Why does excessive water content sometimes occur at the service end of standard dryers?
This happens because the rapid flow of compressed air can carry a large amount of condensed water away from the refrigerated dryer before it can be properly discharged.
What makes the GA series air-cooled refrigerating dryer different?
It features a horizontal evaporator designed with an upright differential configuration and is equipped with a refrigerant high-pressure secondary condensation device at the bottom. This utilizes gravity to prevent condensed water from being carried away by the fast air flow.
What factors must be considered when choosing a cold dryer?
You must consider five key factors: the flow rate of compressed air, working pressure, inlet temperature, ambient temperature, and the required pressure dew point.
How is the processing capacity of the cold drying machine calculated?
It is calculated by dividing the compressor's exhaust volume by correction factors related to working pressure, temperature, and ambient conditions (e.g., Exhaust Volume ÷ 0.75 ÷ 1.12 ÷ 1.0).
