AIR DRIER

These types of Air Driers are designed to take advantage of the natural tendency of desiccants to establish equilibrium with their surroundings and to deliver dry and clean air used for pneumatic instrumentation or critical applications.

The drier consist of two towers with beds of activated alumina absorbent desiccants. The System completes with prefilter, oil filter, after filter and also with necessary valves, pipelines, fittings, timers and electrical items etc. When the wet air from the compressor enters in the bottom of alumina filled tower losses all its moisture contents and the dry air exists at the top of the tower. Due to absorption all the desiccants were saturated. Then an automatic timer diverts incoming air to another tower. When one tower is drying the air, the other tower regenerates the desiccants. This is a self contained Process, which uses a purge of already dried air to pass through the desiccant bed at lower pressure. This Purge air removes the absorbed moisture from the absorbent desiccant.

This process is automatically reversed from one tower to the other on a timed sequence basis [5 minutes drying and 5 minutes regenerating].

The drier is fixed on a base frame with all accessories and in a ready condition to operate. Mere bed bolt is enough to erect the driers. A rain, dust and moisture free room is preferable for erection. Adequate floor clearance and the surrounding temperature should be normal level around the drier is required. To get the best result the inlet air to be sufficiently cool [between 25 deg C to 40 deg C]. So an after cooler is necessary to get the above level. Optimum size of Tower is used to avoid excess usage of purge air pressure drop excess desiccant dust and obtain a better result of 40 deg C dew point. All types of spares are ready stock to avoid

customer's break down problem. Capacities ranges from 5CFM to 5000CFM.
