How does the delair refrigeration dryer work ?Hot, moist compressed air, precooled by outgoing cold, dry air, in the air-to-air heat exchanger (1), enters the air-to-refrigerantheat exchanger cooling it to the evaporating temperature of the refrigerant and condensing the entrained contaminates. The cyclone separator separates condensate from cold air discharging it through an automatic drain trap. Re-entering the air-to-air heat exchanger, the cold dry air is reheated by the incoming air to approx. 10°C below the incoming air temperature. The compressor (2) delivers the hot high pressure gas via the liquid separator to the air-cooled condenser (3) where the remaining refrigerant is condensed and collected in the receiver (Air Cooled). The subcooled liquid expands to evaporating pressure in the expansion valve. Heat is withdrawn from process air by the refrigerant entering the evaporator. Before entering the compressor, the vapourised refrigerant is separated from droplets by the liquid separator. This cycle is continuously repeated.
Features Highlight:

• Available in 28 standard models 
• Capacities from 10.6 cfm to 3540 cfm 
• Mimic display to read out dewpoint, operating status, faults indication 
• Provides pressure dewpoints down to 4°C 
• Unique, patented, foamed in heat exchanger. 
• Outperforms other dryers. 
• Certified and reliable performance 
• Compact design Optional Features 
• Filters and/or total dryer bypass line with valves. 
• Special Delair filters for removal of water, oil mists, oil vapour and dust particles with electronically operated drain valves 
• Explosion proof controls for offshore application.

Description:

• Refrigeration type dryers use less energy and hence are lower in first and operating costs
• The refrigeration type air dryer is a packaged self-contained unit fully automatic and produces a steady level of dew point
• There is no regeneration cycle with complex valves no periodic recharging of chemicals oil in the air stream does not affect performance
• The Heart of the system is the special foamed in, patented Heat Exchanger which makes it outperform other Dryers
• The function of the air to air heat exchanger is to lower the load on the refrigerant system and secondly by warming the outgoing cold air pipelines to the required temperature
• The refrigerant to air heat exchanger (s) further cools the air to the required temperature thus condensing the water vapor from the air which is automatically drained

Applications:

• Pharmaceutical Industry
• Food Industry
• Leather Industry
• Automobile Industry
• Steel Industry
• Powder coating
• Textile Industry
• Spray painting.

How does the DC series Adsorption Dryer work?
The DC dryer has two pressure vessels / towers filled with desiccant. While the air is dried in one tower / vessel, the desiccant in the other is reactivated, thus maintaining a continuous and automatic operation.

• Drying : The wet compressed air is led into one of the adsorber towers through solenoid valves in the smaller models, and through pneumatically controlled valves in the bigger models. This wet compressed air is passed through a specially designed sieve tube for uniform flow of air through the desiccant tower, where it is dried. Part of this dried air is taken out and used for purging or reactivating the desiccant of the tower saturated with moisture. The balance dry air leaves the dryer through a check valve.
• Regeneration : The purge air with a low water vapour pressure is passed over the desiccant (saturated with adsorbed moisture). The desiccant loses the adsorbed moisture which is expelled into the atmosphere via outlet valve through a muffler. Now the desiccant is dry and ready for adsorption. The heat of adsorption released during this process raises the temperature of the desiccant, which in turn stimulates the liberation of the adsorbed water vapour and thus, the regeneration.
• Change Over : After a preset time, the desiccant in the first tower needs to be regenerated as it is saturated with the adsorbed moisture. The outlet purge air valve of the second tower is energised in a sequence, where the outlet valve closes first to pressurize the adsorbent in the tower in regeneration mode. The second tower now becomes the adsorber while the first changes to regeneration mode. The wet compressed air now passes through the fresh regenerated adsorber tower thus setting up a continuous process.

Working Principle

Stage I

The Air at specified pressure and velocity enters the Dryer cylinder and impinges on the Demister pads. This reduces the velocity and created obstruction if the flow of air resulting in physical water separation from compressed air. Collected water is viewed in the slight glass and can be drained out manually.

Stage II

Compressed air free of water droplets pass through a bed of desiccant where further drying of air takes place through adsorption of water vapor in the compressed air by the desiccant.
Stage III
Dry air then passes through a 5 Microns Sintered Bronze after filter to remove the containments created due to desiccant attrition and then is given to the application point.
