Compressed Air Dryers

Product Details:

Desiccant dryers, sometimes also known as absorption dryers, operate by absorbing water vapor into a porous media with a high affinity for water. Desiccant air dryers work on mass transfer principle. Desiccant dryers have two vertical towers filled with highly hygroscopic media (desiccant). The wet air coming into the dryer is passed through the towers filled with the desiccant. This desiccant material attracts the water from the compressed air via adsorption. As the water holds on to the desiccant, the desiccant "bed" becomes saturated. When the media in the first tank becomes saturated, the air stream is automatically redirected through the second tank. A portion of dry air coming from the second tower is diverted into the first tower to regenerate the saturated desiccant and prepare it for the next cycle. The diverted air is purged out of the dryer.

Flame proof air dryer for use in hazardous environment like CNG Gas Station, refineries, gas processing plants etc are also available

Product Details:

In Desiccant Air Dyers, the compressed air is passed through a pressure vessel filled with an adsorbent media such as activated alumina, molecular sieve or other desiccant material. Two vessels with desiccant are used. The desiccant can bring the dew point of the air down to -40 degrees Celsius or below. This means that the air will not condense water until it is cooled to -40 Degrees Celsius. Wet air enters the vessel through a pre-filter to remove any oil and other contaminants which protects desiccant’s long life. Pre-filtered air enters into adsorption tower through solenoid valves controlled by an electronic timer. In practice two vessels are used; one vessel is drying the air, while in the other the moisture absorbed by the adsorbent in the vessel is being regenerated. After a pre-determined period of time, the switching of the vessels takes place with the help of the electronic timer. The other absorber tower undergoes regeneration with a portion of dry air exits from adsorption tower. This regenerated air is purged out of the system.

Refrigerated Dryers works on Heat Transfer principle. Saturated compressed air enters the Pre-cooler / Re-heater (air to air heat-exchanger), where it is pre-cooled by exchanging heat with the outgoing cold air, which reduces heat load to the evaporator. The inlet air is further cooled in the evaporator (air to the refrigerant heat exchanger) to the required dew point. The cold air is then reheated when it passes back through the air-to-air heat exchanger (precooler/reheater). A refrigerant compressor and condenser supply low-temperature refrigerant to the evaporator. The thermostatic expansion valve and the hot gas bypass valve match the operation of the refrigerant system to the compressed air cooling load. In the evaporator, heat is transferred from the compressed air into the refrigerant.

The process cools the air, reducing its capacity to hold water vapor and resulting in moisture condensation. The excess vapor condenses and is removed from the air system by a separator and automatic drain valve. Our consistency in continuous improvement in design for renovating small model results into tube-in-tube type dryer. The copper tube-in-tube design provides a maximum surface area which results in optimum heat transfer

Product Details:

Compressed air is used during the working of CNG pumps. It is necessary that dry moisture free air should be supplied during the. We manufacture compact,  high pressure (up to 16 kg/cm²) desiccant air dryers that can be supplied along with the CNG pumps.
