Mellcon Engineers Pvt. Ltd. Delhi

we offer refrigerated air dryer. a refrigerated air dryer is the most commonly used. type of compressed air dryer gas dryer for most plant applications for the drying of plant air and other utility gases like seal gas , hydrogen gas for generator cooling , nitrogen gas drying etc. where a dew point of (+2) deg. c. at line pressure i.e. (-22 )deg. c. at atmospheric pressure) is an acceptable norm. this type of dryer finds application in fly ash conveying , seal gas drying . general plant air , hydrogen gas dryer used in generator cooling application & pneumatic tools operation. as much as 2300 gallons of moisture can be removed from a100 cfm pneumatic system operating at 100 psi in 12 months of 3 shift operation, moisture which without a refrigerant air dryer, would have passed through the delicate pneumatic equipments & instruments features of refrigerated air dryer a full range of aircooled 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

Mellcon dew point apparatus is the most economical, simple, errorless system for the spot checking of dew point temperature of any compressed air gases. This consists of a closed cylindrical glass with two chrome plated tubes, a low range thermometer (-50+40 deg.c) and a dry ice maker. Air gas enters to cylindrical glass through one chrome plated tube and exhausts. The other chrome plated tube is centrally placed in the cylindrical glass and thermometer is placed in it. Make dry ice (solid c02 ) with the help of dry ice maker & a co2 gas cylinder. Pour some ether acetone in the chrome plated tube having thermometer, and slowly put dry ice pieces into this liquid to reduce the wall temperature of the chrome plated tube. At a particular temperature the dew frost will start forming on the walls of the tube and the same temperature can be noted from the thermometer. This is the dew point temperature of that particular air gas.

We are offering auto drain trap. Mellcon auto drains are most economical, simple & maintenance free systems. The compressed air gas contains inherent moisture which will condense in receiver tanks, filters and pipelines, which requires regular draining systems. Auto drains are available in two options namely: 1) electronic timer drain. 2) level based zero loss condensate drain

We offer hoc type air dryer. Energy conservation by heat of compression type compressed air dryer is a breakthrough in compressed air drying technology. The hot air from the oil-free air compressor at 120°c or higher temp, is used directly for regeneration of the desiccant bed in the compressed air dryer. After regeneration, this air is cooled down to 40°c in the water cooled after cooler and then it is dried in second tower. Thus the use of heaters is eliminated. For eg. In the 6 + 6 hrs. Cycle the hot air is fed for regeneration of desiccant bed for 4 hrs. And for balance 2 hr. A changeover takes place where the air is first cooled in an after cooler, then dried and before going to the outlet, cools the regenerated desiccant bed, thus bringing it down to ambient temperature. This cycle is reversed for the next 6 hrs. Where the adsorber drying the air in the previous cycle goes for regeneration and vice versa. There is considerable power saving in these type of compressed air dryers and the dew point is also better than the refrigerated type of compressed air dryers . Main advantage of heat of compression type compressed air dryer is the energy conservation and heat recovery achieved which is being wasted in after cooler in the conventional air dryers is now used to reactivate the desiccant.

Ellcon offers fully automatic and effective ready to use effecient refrigerant recovery system with power range from 120 watts to 1200 watts. It has a volumetric capacity range from 4-6kghr to 40-45kghr. To start the unit connect the service hose to the lower side of the refrigeration system and press the start button. The unit will start operating and the refrigerant gas gets extracted and distilled. It will turn off automatically after all the gas is removed. It will pull a 10 degree vacuum and if a positive pressure is sensed the unit will start automatically.
