Refrigeration Dryers By Trinity Tradex Pvt. Ltd.

Refrigeration Dryers  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 +3o c. Compared to other Air Dryers the HX Series of Trident has a very low running cost. Operation           Warm compressed air enters the Air/Air heat exchanger where it is precooled by outgoing cold refrigerated air. Pre-cooling makes it possible to use a smaller (more economical) refrigeration Unit. Then the pre-cooled air enters the Air to Refrigerant heat exchanger where it is cooled down to +3 c. At this cool temperature, water condenses into liquid droplets, which are removed from the air stream by a very efficient Demister and automatically discharged to drain by a Trident Automatic drain valve.           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 through out the dryer's life. Any dust, dirt or oil will be washed from the air system along with the condensed moisture at the De-mister. Salient Features   Condensing Temperature control for ambient Temperature variations.   Hot gas by-pass circuit for partial load.   Maintains constant pressure dewpoint.   Compressor safety through HP cut switch.   The advanced mimic display indicates the functions & faults if any.   Trident Automatic Drain Valve provided in Demister & Heat exchangers    for effective Dryer functioning. Application           Trident Refrigeration Dryers are suitable for all compressed air systems like :   Plant Air   Machines   Cylinder applications   Foundry   Textiles   Engineering   Glass blowing Specification of Dryer Model Flow incfm Power Consumption in KW* EndConnection Dimensions in mm **HeatExchanger Weighin Kg A S H W D R 134a R 22 R 134a R22 Coldspell 40 40 - - 0.36 - 1 ff BSP 600 450 550 BPH 55 1 ff BSP 700 450 480 IHE 55 Coldspell 50 50 - - 0.36 - 1 ff BSP 600 450 550 BPH 55 1 ff BSP 700 450 480 IHE 55 Coldspell 60 60 - - 0.36 - 1 ff BSP 600 450 550 BPH 55 1 ff BSP 700 450 480 IHE 55 Coldspell 80 80 - - 0.85 - 11/2ff BSP 820 500 600 BPH 70 1 ff BSP 710 480 530 IHE 60 Coldspell 100 100 - - 0.85 - 11/2ff BSP 820 500 600 BPH 70 1 ff BSP 710 480 530 IHE 60 Coldspell150 150 - - 1.02 - 11/2ff BSP 1000 650 800 BPH 110 Coldspell 200 200 1.37 - - 1.44 2ff NB 1000 650 800 BPH 130 Coldspell 250 250 1.37 - - 1.44 2ff NB 1000 650 800 BPH 130 Coldspell 300 300 1.37 - - 1.85 2ff NB 1320 950 1150 BPH 240 Coldspell 400 400 1.70 - - 2.40 2ff NB 1320 950 1150 BPH 260 Coldspell 500 500 1.91 - - 2.40 2V2ff NB 1320 950 1150 BPH 290 Coldspell 650 650 2.68 - - 3.30 2V2ff NB 1375 1150 1300 BPH 350 Coldspell 800 800 2.68 - - 4.00 3ff NB 1580 1380 1530 BPH 490 Coldspell1000 1000 3.59 - - 4.80 3ff NB 1580 1380 1530 BPH 580 Coldspell 1200 1200 5.05 - - 3.92 4ff NB 1530 1280 1530 BPH 620 Coldspell 1500 1500 5.80 4.78 - - 4ff NB 1380 1280 1080 BPH 900 Coldspell 2000 2000 7.10 7.25 - - 6ff NB 1750 1480 1980 BPH 1020 For any other capacity contact factory.
