Compressed air with saturated water vapor enters the dryer’s pre-cooling device, in which, the entered hot air is cooled down by the outgoing cold air partly, thus reducing the load on the system (this process is pre-cooling). Pre-cooled air enters the evaporator. Here, heat released by the air is absorbed by media and the air reaches the pre-set temperature (2 4^oC). After being cooled, the water vapor in the air condenses into droplets and is separated from the air by steam separator and then flows out of the dryer through automatic drainer. Leaving the separator, cold air enters into the pre-cooling device’s shell side for heat exchange with hot air in the inlet and leaves the dryer after being heated to a temperature about 10^oC lower than that of the inlet air. This reheating prevents the second moisture condensation in the outside exit air pipeline and downstream pipeline, increases the energy of the air and improves the effectiveness. In addition, after passing through the dryer, solid dust of over 3μ in the compressed air is all filtered, and the air source quality reaches the clean and dry requirements.

Micro heat regenerated adsorption dryer works in a twin-tower alternative operation mode. Compressed air enters the dryer’s tower A through valve 1A (1B is closed), then is dehydrated and dried under the unique adsorption action of the adsorbent. Finished gas flows to the gas using point through valve 5A (5B is closed); meanwhile about 5% dry air source enters tower B through valve 4B (4A is closed) after being heated by the heater, the adsorbent in which is regenerated after a certain period of heating. Cold blowing begins when heating is stopped, which cools down the adsorption bed in the dryer’s tower B (for use in the next cycle). Finally, the air is discharged into the atmosphere through muffler. Before switching in the second half period, turn off valve 2B and open valve 1B to equalize the pressure in the two towers (to ensure pressure stability when using the gas and avoid the impact and jitter of the dryer), and the second half period work begins at the same time (the dryer’s tower B works and tower A regenerates). The process is similar to that of the previous half period.

• They save energy besides economising purge by reducing the loss of purge to a minimum of 50%.
• They have controllers with lucid functional displays that are programmable.
• They secure undisturbed operation despite tower changeovers.
• The moisture load is lessened by the auto drain valves in pre and oil filters. Therefore the desiccant life is secured without any extra cost.
• The inclusion of a unique purge economizer in the latest microprocessor based controller which facilitates manual setting up of the dryer load. This device can not only accept upto 3 compressor load/unload contacts but also compute the dryer load dynamically. According to these settings done, the purge can be set. Also, the purge air can be controlled according to the pressure input accepted by the controller.

Compressed air leaving a compressor & after cooler is saturated with moisture, dust, oil (in lub, compressor & other particles) which is responsible for major problems. With this, we can attain trouble free & operationally safe production by dry & clean air.

• Moisture washes away lubricants there by increasing wear & tear for expensive pneumatic instruments
• Moisture from sticky emulsion with dirt, scale & oil, plug precision orifices resulting in shutdown
• Corrosion of pipe lines & pneumatic instruments
• In process industries, moisture can react chemically or contaminate the product by forming unwanted compound
• By installing drycool air dryer in the compressed air system moisture related problems can be eliminated
