Air Dryer for Nitrogen Generation Plant

Work Condition and Technical Data:

Inlet temperature : ≤45 °C

Cooling method: Water-cooled

Designed dew point: 2~10°C

Inlet pressure: 0.6~1.0MPa

Pressure drop: ≤0.02MPa

Cooling water inlet temperature:≤32°C   

Cooling water inlet pressure:0.2~0.4MPa

How it works?The compressed air goes into the pre-cooler for pre-cooling.Then goes to the heat exchanger,further bringing down the temperature by the refrigerated air,meanwhile,draining out the condensate water.The air entrance to the evaporator for heat exchanging among the refrigerant,and further cooled by the refrigerated systems.The compressed air goes through pre-cooler heat exchanger and evaporator for cooling step by step,vapor of the air coagulates liquid water,and then through gas/liquid separator,draining out the liquid.The dried air comes out from gas/liquid separator,next,goes through heat exchanger for other flow.It’s became calefactive when leaving the dryer.

Product Features

1.Advanced technology

We accumulated Hankison’s technology and adopt more scientific,efficient design in the basic of the actual working conditions of China.HOLYSUN brand refrigerated compressed air dryer became one of the leading brands in China because of its’ advanced technology,reliable running and low dew point.

2.Prefect refrigerated system configuration

Initial parts come from foreign famous brands to ensure efficient & system reliable running & life as well.

3.Energy conservation

New design of the heat exchanger, adverse current structure,perfect returning temperature and it won’t freeze.Ripple pipeline of both internal and external of the heat exchanger to increase the using rate of cooling air,Evaporator is made from laminose copper pipeline with aluminum flake,high efficiency of heat exchanging of the perfect structure.

4.Gas liquid separated thoroughly

Filtering separated with HANKISON element.Thorough separation,avoid the second vaporizing of water,ensuring dry effect.It is better than cyclone separation and it will reach efficiency at 99.99%.

5. Good drainage system

It adopts 3 grades for draining,Electronic drain can lots of condensate water and oil contaminant so as to keep clean and dryness of the system and air, meanwhile reduce system load.

6.Unique outer box and air exhaust design

No negative pressure and counter current,excellent heat dissipation and convenient for maintenance.

7.Multi-control of circuitry to supply

Multi-control of circuitry to supply to different users(single control;integrate circuit,linkage control,PC panel,frequency conversion,etc.)

8.Superior condenser 

Condenser made from fin copper, slow flow, multi-cycling and high heat exchanging tate.it won’t freeze for a long time use.
