Absorption Air Dryers - Heated
     
    Heat of Compression Air Drier(Series DC)
     
              Trident Refrigeration Compressed Air Dryer is an ideal solution for clean and compressed dry air. It is the result of extensive design and prototype testing and provides a consistent dew point of +3 c. Compared to other Air Dryers the HX Series of Trident has a very low running cost.
    No Loss Split Flow Air Drier(Series DS)

              Trident make split flow dryers offers dewpoint of -40c depending on the  requirements. These dryers utilise heated part of air for regeneration and there is no air loss in this type of dryer. These dryers are available for any capacity higher than 500 scfm.

    Internal Heated Type Air Drier(Series D)

              Trident make internal heated dryer offers good dewpoint.Heaters are kept inside the insulated tower and the tower is heated to the required temperature and pumped.These dryers are available for any capacity higher than 500 scfm.

    Blower Heat Reactivated Air Drier

              Trident Blower Heat Reactivated Air Dryers offers a very good dew point of 50c or better  depending on the requirement.These dryers are useful for instrumentation air meeting the quality requirement of ISA s7.34. Available for any higher capacity from 500 cfm to 4000 cfm. 

    Operation
     
             The Blower Heat Reactivated Dryer works on the principle Thermal swing. The desiccant adsorbs moisture from the compressed air to deliver dry air. The desiccant bed saturates over a period of time. The saturated bed is regenerated by heating with hot air generated using a blower. Hence the dryer is called blower heat reactivated desiccant dryer. Since the temperature of the bed swings between the compressed air temperature and the regeneration temperature it is called Thermal swing type. The hot air from the blower passed through a heater. This makes the air very dry. The hot air then heats up the desiccant bed. When the bed is heated it gives up the moisture adsorbed and is ready for adsorption. The hot air carries this moisture to the atmosphere. After the regeneration, heated desiccant bed is cooled by the flow of air to suit the application conditions. Final Cooling is achieved by a no loss compressed air cooling method, resulting in a no Dewpoint spike system. Trident dryer comes with a dewpoint based control system as a standard. The tower changeover takes place only when the bed is saturated, resulting in energy saving and extended life. The dryer with its control valves and controller manages the drying, regeneration and repressurisation of the desiccant columns automatically and thereby delivering continuous dry compressed air.

    Blower Heat Reactivated Dryers are best suited for applications requiring large volume of compressed air at low dewpoint. For the above conditions the dryer works out very economical energy wise. Trident blower heat reactivated dryers are built from the start for customization. Since the air volume is large cusomisation delivers substantial energy savings.
