Refrigeration Compressed Air Dryer - Coldspell

An ideal solution for clean and compressed dry air is provided by Trident, one of the experts among the refrigerant air dryer manufacturers. Extensive design strategies and prototype testing culminates in Trident’s amazing products that offer a constant dew point of +3 degree Celsius. Also, the HX series of Trident offers a very low running cost unlike the other air dryers. Some exclusive features of these products are:-

The cold dry compressed air passes back through the secondary side of the Air to Air heat exchanger where it is reheated by the incoming warm air. Reheating the outgoing compressed air increases the volume of the air enabling it to do more work and it also prevents downstream pipe sweating. Trident heat exchanger has no extended surfaces or sharp corners that collect dust, dirt or oil residue. Their self-cleaning smooth surface tube in shell and tube design will maintain the same heat transfer efficiency throughout the dryer's life. Any dust, dirt or oil will be washed off from the air system along with the condensed moisture at the De-mister.

  • Maintaining of a consistent pressure dew point.
  • Control of the condensing temperature for atmospheric variations in temperature.
  • The safety of compressor provided by the HP cut switch.
  • The advanced mimic display that indicates the functions and faults if any.
  • The provision of Trident automatic drain valve in Demister and Heat exchangers for efficient dryer functioning.
  • Ranging from 20cfm to 2000cfm and above.

Heatless Air Dryers - Dryspell Plus

The Dryspell plus is an ultimate compact dryer with valves and piping built into the manifold. These dryers are suitable not only for point of use but also are available for 10, 20, 30, 45, 60, 100, 125,200, 250, 300, 375 scfm. Paint shops, instrumentation, hand tools, powder coating, CNC machines, automobile garages, dental equipment, Pharma are some areas where these dryers are applied extensively.

Some of the key features of these dryers are:-

  • Provides manifold construction
  • Provides a shuttle valve for low pressure drop that is controlled by the microprocessor.
  • Equipped with a built in microprocessor based controller.
  • Equipped with a pre filter that has a borosilicate glass fiber element.
  • Purge Economiser - Reduces purge loss and energy according to load requirements. Accepts dewpoint meter signal to cycle on dewpoint temperature instead of time
  • The pre filter drain valve is not only timer based but also gets activated by the controller.
  • Ranging from 10cfm to 375cfm

Compressed Air Dryers (Heatless) DP Series

Principle of Operation

Pre-filtration: The moisture laden compressed air passes through the pre filter. Here moisture load is reduced through coalescence. Condensation is removed through the drain valve ADV1. At the oil filter, oil vapours are removed completely and a small level of water condensation is purged through the valve ADV2.

Drying: The Towers are filled with Activated Alumina as desiccant (Molecular sieve available as option). When air passes through Tower 1 which consists of “DRY” Desiccant, it gets completely dried, and passes through the check valve and the after filter. At the after filter, Desiccant fines are removed. Therefore, dry compressed air passes out at the outlet.

Regeneration: Regeneration takes place in 2 stages a) De-pressurization b) By passing Dry air. Tower II consists of fully moist desiccant in pressure. This is suddenly De-pressurized by opening the purge valve. Water molecules seep out of the desiccant and appear on the surface. “Super Dry” purge air passes through the Regeneration “Nozzle” and the desiccant bed thereby completely carries away the water molecules. Tower II gets regenerated and is ready for the next drying cycle after the re-pressurization.
