We offer liquid dryer. Mellcon Engineers are the manufacturers of complete range of Liquid Dryers, solvent dryers dehydration equipments & dehydrators Designed for removal of dissolved water from a variety of liquids critical to Industry. These dryer are designed for a continuous duty like Twin tower liquid dryer system or single tower liquid dryer system for batch operation i.e. Desiccant systems for liquid dehydration have two basic cycles:- Drying- The removal of dissolved water from liquids is accomplished by passage of the wet liquid through a freshly reactivated packed column of granular desiccant material like silica gel, activated alumina or molecular sieves. Continuous operation is accomplished by the use of dual adsorbers, with one tower on the process stream while the other is being reactivated. Reactivation- Reactivation is accomplished in the following steps: Drain the tower of liquid product Heat the desiccant to release water. Remove released water from the tower. Cool and refill.

We offer Hot Air Blowing Equipment. Mellcon Engineers are specialized manufacturers of Industrial Hot Air Blowers & Air Heaters equipments for Bus Ducts dehydration & moisture removal technology during long shut down periods. We have supplied large number of Hot Air Blowing Equipments to various projects e.g. Neyveli Lignite Corporation, NALCO Angul, GMDC Ahmedabad, NTPC Rihand, Panipat Thermal Project, DVC Mejia, Pendent Cement Bhutan etc. Inspection was carried by leading consultants like MECON, M.N Dastur, DCL, Desein, Tata Projects etc. Mellcon make Hot Air blowing Heaters are equipped with Digital Temperature Indicating Controller (TIC), Blind Temperature Controller (BTC). TIC and BTC are having individual set points, by which the temperature of the Air Heater can be controlled. Set temperature of TIC is at outlet temperature can b maintained as required, So that this will maintain the temperature of heater at this temperature by energizing & de energizing the Heater according to the temperature. BTC which is provided as extra safety device is set at 10 degree C above desired outlet temperature.This will cut off the heater if the temperature increases more than its set temperature and alert the operator by an audio alarm so that the temperature will not increase beyond control.

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.

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
