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 Tridents 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.

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.

Air from the Dryer is sent through the coalescing filter where the water and oil coalesce and get purged through the drain valve. Two aluminium towers filled with carbon molecular sieves are used for continuous production. The dry air passes through the aluminium tower where oxygen is adsorbed into the molecular sieve and pure nitrogen is let out. Part of the produced gas is used for regenerating the sieves.APPLICATIONMetallurgical IndustrySynthetic And Fiber IndustryChemical IndustriesFood Packaging IndustryPharmaceutical IndustryCable & Optical Fiber IndustryElectronic IndustryPlastic Injection MoldingLaser CuttingSemiconductor ManufacturingMetal Heat TreatmentGlass Industry
