    Mr.Kerry Robinson from Australia
    today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

Time Proven Design:

*Rust Prevention: have been treated against corrosion, it does not need to be treated against corrosion and dust again within 10 years on the promise that normal maintenance is ensured.

*Various Valves provides reliable and long service life.

*Vessels have a large filling level of desiccant bed that allows compressed air has enough time to contact with desiccant. That is, more efficient on drying process in the Adsorption Dryer.

*Generously sized silencers ensure efficient noise reduction for the escaping regeneration air.


Ease of Monitoring:

*PLC Control Panel

*Electronic(Automatic)Drain Valve.

Safety Protection Systems for overheat and Systems Alarm and Stop for Errors and Overworking. Expand Machine Life.

*Each valve is controlled individually with a time-delay, which results in overlap-free switch-over without pressure peaks between adsorption and regeneration.


1.High Performance pneumatic Valves

Oil-less pneumatic valves are designed specifically for high temperature applications and feature stainless steel internals and filled PTFE seats.

2.Low wattage heater with high temperature interlock

Low-wattage high incoloy sheathed heater for efficient regeneration.
Heater high temperature with interlock alarm provides continuous monitoring of heater sheath temperature. The heater will de-energize in a high temperature condition.


3.High Efficiency Centrifugal Blower

Reliable, quiet generation of purge air. Intake filter is positioned for convenient access to facilitate filter element changeout.


4.High performanced desiccants

Double fixed bed layers, respectively filled with high performanced activated alumina and molecular sieve.


5.Advanced PLC controller

PLC Controlling system executes and monitors all dryer functions, 7’’ Touch screen panel displays dryer status.


6.Dew Point Display

Highly accurate ceramic dew point sensor and high dew point alarm.


7.Pressure Gauges

Stainless steel gauges, located on each tower, provide visual indication of pressure during drying and regeneration processes.

8.Large Purge Mufflers

Large mufflers minimize noise and include built-in safety relief valves.
