Use of compressed air is an economical form of power for pneumatic operation, instrumentation and other applications. Therefore, it requires efficient filtration for removal of moisture and oil for smooth operation of any pneumatic system. To facilitate the effective functioning of various pneumatic systems, we offer an extensive range of Air / Gas dryers. We lay maximum emphasis on consistent quality products and follow a well framed quality systems with back-up of a well trained work force to ensure quality. The various types of air / gas dryers offered by us are as follows:

The working principle of heatless air dryer is based on “Pressure swing absorption” and the operation is fully automatic & simple. The moisture from compressed air/ gas is removed by absorption. Two drying towers are provided that keep on changing their position according to the designed cycle. While in one chamber drying of air is in operation, the other gets re-generated by de-pressurization and using a small portion of the dried air. This dried air flushes out the moisture from the adsorption media, adsorbed in previous cycle. Slide piston valve, pneumatic diaphragm operated exhaust valves are provided for complete automatic change over. Moisture level 80 ppm (dew point – 40^oC) or less can be achieved. The dryer is very compact and very easy for operation and maintenance.

In these air dryers, external heat used for regeneration of the adsorbent. We offer various dryers that are classified as under:

Internal heaters type:
The electric haters are embedded in the drying towers which heat up adsorption media unto required degree and the absorbed moisture is then flushed out with the help of a very small amount of dried air/ gas.

Blower heat regenerated:
In blower heat regenerated dryer, we can save compressed air which is to be washed in regeneration. A blower provides the atmospheric air which is heated in an external heater and is passed through the drying tower from where it takes away all the moisture.

No purge loss split flow type:
The wet compressed air/ gas is split at the inlet through differential valve. Part of the stream is passed through an external heater and then the tower regeneration where it caries the absorbed moisture and then passed through a cooler where the absorbed moisture is condensed and separator.

Heat of compression type :
In heat of compression dryer, hot compressed air from compressor is directly passed through the drying tower to be regenerated and hence the use of heater is eliminated. However, a small capacity electric heater is provided in the incoming hot air line which takes care of the lower temperature of the hot air due to any reason. There is considerable power saving in this type of dryer and dew point unto – 50 deg C. can be achieved.

Refrigerated air dryer is the most commonly used compressed air dryer for most industrial applications. It is extensively used for the drying of plant air and other utility gases like hydrogen gas, nitrogen drying etc. In this type of dryers the moisture present in the compressed air/gas is condensed by chilling it down from ^o to 4^oC by using effective refrigeration cycle and the condensed moistures is separated by efficients filters. The dew point is 23^o c (at atmospheric pressure) but the running cost is very low.
A full range of air-cooled as well as water cooled refrigerant air dryers are available for moisture removal & to provide dry clean air to any size and type of compressed air & pneumatic systems. The power consumption reduced by upto 10% over conventional refrigerated dryer system. Moreover, the advance design removes moisture dirt and oil contamination by either impaction or integral filtration and ensures maximum protection for pneumatic compressed air equipment at all times

We offer Dry Air Plant in which complete assembly is mounted on a common skid. This system is complete with water cooled after cooler, air receiver, (Horizontal / Vertical) and Heatless Air dryer. The system is ready to install and requires power connection, water connection and air inlet/outlet connection.
