Air & Gas Dryers

The simplest way of removing moisture from compressed air is to reduce the temperature. In this dryer compressed air is passed through a heat interchanger where cold refrigerant at around 3 Deg C is passed through the other side of the heat interchanger. At this temperature most of the moisture is condensed which is then separated and drained out in moisture separator.

Salient Feature:-

• Simple Non Cyclic operation.
• Low operating cost.
• Low Noise.
• Zero Purge Loss
• Even lubricated air can be dried
• Suitable for any capacity
• PDP of 3 Deg C
• Electronic Control
• Environment Friendly Refrigerant.

• This is the simplest of all desiccant based air dryers. In this dryer two desiccant towers are used. While one tower is in drying, second tower undergoes regeneration simultaneously. Part of dry air coming out from tower in-line goes for regeneration of the second tower. Tower changeover takes place at every 5 minutes by a sequence controller mounted in control panel.

  Salient Features:-

  1. Simple operation.
  2. Easy to maintain.
  3. Microprocessor based Controller with Purge Saver. 
  4. No need of heater or cooler.
  5. Atmospheric dew point of (-) 40 to (-) 60 Deg C can be easily achieved. Simple operation. 
     

• This is an improvised version of heatless dryer where purge air loss is very very low due to regeneration is achieved by dry air at low pressure and at high temperature. To achieve this heaters are provided to heat the purge air to around 180 Deg C, which enhances its moisture carrying capacities. This hot purge air at low pressure is passed through the desiccant bed to regenerate with small quantity of purge.

  Salient Features:-

  1. Saving in purge air loss.
  2. Dew point upto (-) 80 Deg C (atm) can be achieved.
  3. Compact design.
  4. Simple operation
  5. Most economical in the range from 200 CFM – 1000 CFM
  Advanced Version of Dessicant Dryer with Saving in purge air loss.

Our range of Heat of Compression (HOC) Dryers offers better utilization of the heat generated that is generally lost due to cooling in after cooler. In our range of Heat of Compression (HOC) Dryers, this heat is utilized to heat the air for regeneration. The hot compressed air is passed via a heater to maintain the temperature around 180 Deg C, which is subsequently passed through the desiccant bed for regeneration. Further, the air gets cooled down after absorbing moisture that later on is drained out in a moisture spectator on further cooling in the after cooler. This cooled air passes through the other tower of desiccant for drying. Listed below are some of the commendable features of our range of Heat of Compression (HOC) Dryers:

• No purge loss
• Saving on electrical Heater load
• Atmospheric dew point of (-) 600C can be easily achieved
• Most economical in the range from 400 CFM onwards

Our clients can avail from us highly advanced Blower Reactivated Dryer that is used to increase the moisture carrying capacity of the regenerated air. The regenerated air is supplied from a blower to the heating chamber for heating. This hot air is passed through the desiccant bed for regeneration. Some of the striking features of our range of Blower Refrigerated Dryers are listed below:

• Low operating cost for high capacities
• Dew point up to (-) 60 Deg C can be achieved
• Most economical in the range from 1000 CFM onwards

We put forth for our clients a comprehensive range of Low Pressure Dryers, which is fully automatic and computerized air handling unit. Our clients can avail both Low Pressure Air Dryer and Low Pressure Nitrogen Dryer at industry leading prices. These Low Pressure Dryers are excessively used in synthetic fibers, chemical process, air curtains and other industrial applications.

We offer Split Flow No Purge Loss Dryer that is widely appreciated for minimizing purge loss. A portion of wet air is circulated through a heater, which increases the moisture concentration in the air that is further used for regeneration. The incoming wet air is divided in a distributor, where 60-70% of wet air goes for drying. However, the remaining 30-40% of wet air is circulated through a heater, increasing its temperature, which then obtains moisture from desiccant bed. Heated air is then cooled in an after cooler, resulting in condensation and the moisture is drained out in a moisture separator. Finally, this air is again sent back to the distributor for redistribution. Given below are some of the salient features of our range of Split Flow No Purge Loss Dryers:

• No purge loss
• No need of blower
• No use of external air thus eliminating risk of contamination
• Most economical in the range from 400 CFM onwards

We offer a specially designed system to condition methane, which is generated through anaerobic digestion. It is used in micro turbines or combustion engines to protect gas compressors and to remove water vapor from low-BTU gas to meet contract specifications. So in order to remove the harmful water vapors and hence, improve the combustible quality of landfill gas and bio gas, we offer refrigerated, landfill / digester Bio Gas Dryer. These dryers are equipped with a patented dew point sensor, a flood level control, stainless steel heat exchanger tubes and moisture separator. We manufacture these Bio Gas Dryers in modular structure for ease of servicing.

To save on purge loss, here part of wet air is circulated through a heater thereby increasing its moisture carrying capacity, which is used for regeneration. In this type of dryer incoming wet air is divided in a distributor. 60-70% of wet air goes for drying while 30-40% of wet air is circulated through a heater thereby increasing its temparature which then takes out the moisture from desiccant bed and then it is cooled in an after cooler where moisture is condensed and drained out in moisture separator. This air is sent back to the distributor where it mixed with incoming air and distributed again.

1. No purge loss.
2. No need of blower.
3. No used of external air thus eliminating risk of contamination.
4. Most economical in the range from 400 CFM  onwards

Heat Of Compression (HOC) Dryer

In non-lubricated air compressors, great amount of heat is generated which is lost due to cooling in after cooler. In heat of compression type dryer this heat is utilized to heat the air for regeneration. In this dryer hot compressed air is passed through a heater to maintain the temperature around 180 Deg C, which is then passed through the desiccant bed for regeneration. After taking out the moisture this air is cooled in an after cooler where moisture is condensed and drained out in moisture separator. Then this cooled air is passed through the other tower of desiccant for drying.
