China GA-HFB Air Dryer - High-Quality Refrigerated Dryer from Top Suppliers and Factory for Dry Compressed Air Solutions
Functional Characteristics
The refrigerating dryer uses the low temperature of the evaporator of the refrigerating system to lower the temperature of the compressed air, and then condense the water out, obtaining a dry compressed air source. However, 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, but also utilizes the principle of gravity to prevent the condensed water from being carried away from the evaporator by the fast-moving compressed air, ensuring the condensed water is completely discharged.
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, pressure, inlet temperature, ambient temperature, and required pressure dew point.
Exhaust Volume: 5.2 m³/min
Exhaust Pressure: 0.8 MPa
Max Exhaust Temp: 50 ℃
Ambient Temp: 38 ℃
Target Pressure Dew Point: 10 ℃
Processing capacity of the cold drying machine:
It utilizes the low temperature within the evaporator of the refrigerating system to lower the temperature of the incoming compressed air, which condenses and separates the water content from the air flow.
Due to the high-velocity flow of the compressed air, a large portion of the condensed water can be carried out of the dryer before it is fully discharged, leading to moisture carryover.
The GA series features a horizontal evaporator with an upright differential configuration and a secondary condensation device at the bottom. It utilizes gravity to prevent the fast-moving air from carrying condensed water away, allowing complete drainage.
You must evaluate five crucial factors: the flow rate of the compressed air, system pressure, inlet air temperature, ambient temperature, and your target pressure dew point.
The required capacity is calculated by dividing the actual exhaust volume of the compressor by the correction coefficients corresponding to your specific working conditions (e.g., Exhaust Volume ÷ Pressure Factor ÷ Temperature Factor ÷ Ambient Factor).
