Adsorption Dryers Compressor

50RD Adsorption Compressed Air Dryer heatless regenerated

⊙ Introduce

Adsorption Compressed Air Dryers are designed for continuous separation of water vapour from compressed air thus reducing dew point. Operation of dryer requires two columns operated alternately. Adsorption takes place under pressure in first column while second column regenerates with a heated ambient air or purge. A dryer consists of two columns, filled with desiccant beads, blower, heater, controller with LCD dicplay, valves, manometers, and support construction. Proven robust design enablesefficient and reliable operation, fast installation and simple maintenance.

⊙ Working Principle of Adsorption Dryer
A large number of air compressor from the inflow of imported diameter, through air control valve: the two entered a drying tower in the bottom, when the air flow to the tower, one of the Humidity will be by suction alumina desiccant stem. So, it will enable the discharge of the air compressor dew point temperature dropped to -40℃,and reached a dehumidification effect. The entire system takes 10 minutes. The entire circulatory system is as follows: When a tower in the desiccant or operation of five minutes, while the other tower is renewable and clean only 4.5 minutes, continued pressure only 30 seconds, so the two towers interactive operation of such duplication. When the machine was operating renewable wind of 12 percent. Superior design, saving maintenance costs.

⊙ High efficiency heat exchanger

➤ Adopting high strength thick copper pipe and oxygen-free welding with quotient silver content electrode; long service life and high heat transfer efficiency.
➤ Adopting anaerobic welding method, the system is free of impurities and keeps the system clean. The whole series of copper tubes are manufactured by mechanical expansion, which are closely combined with fins, with low heat transfer impedance and high heat transfer efficiency.
➤ The coil is cleaned by sound wave and there is no residual oil. It is not easy for eel slices to stick dust, and no carbonization occurs during welding.
➤ Adopt the anaerobic welding method to ensure the cleanliness of the system.

Reliable Design
Supportive Ceramic Balls used at the bottom of adsorption tower make uniform air-flow distribution, in this way, desiccant can be protected from soaking and also get longer service life, together with special designed stainless steel flow divider, pressure loss can be greatly reduced.
Special designed high performance desiccant can get best dew point.
A full range of standard configuration for high performance pneumatic valve, when it's running, reliability and pressure loss are significantly better than the film valve, solenoid valve.
Configuring multiple protection of electric heater, greatly improving the reliability. Standard gas control valve control with high efficiency oil, dust filter.

Various control options
Standard configuration is using reliable PLC controller.
Optional Siemens and ABB brand PLC or touch screen and etc.
We can meet various customer requirements for communication, connecting RS485 I/O, Profibus or Modbus to Ethernet.

Energy-saving
LDCS-Load Dependent Control System ensure the case that performance is best and at the meantime to control the purge air loss accurately, compared with fixed cycle time control type, LDCS could save at least 8% comprehensive energy consumption.
DPOS-Dew Point Operation System can delay adsorption time under unstable load, DPOS could save at least 75% comprehensive energy consumption.
