Glass Blowing Refrigerated Compressed Air Dryer remove the water content in the compressed air by cooling the air so that the water condenses. Coldspell dryers are available in a wide range of capacities. You should be able to find one in this range to meet your compressed air drying requirements. Should you have any special needs, please contact Trident. How Coldspell dryers work The warm compressed air entering a Coldspell dryer is pre-cooled in the air–air heat exchanger by the stream of cold air flowing out. The pre-cooled air passes through an air–refrigerant heat exchanger. Here it is further cooled, down to +3°C to +7°C. At this temperature, most of the water in the air condenses, forming liquid droplets. This condensate is removed from the air stream by a very efficient demister and automatically discharged from the dryer by a Trident automatic drain valve. The cold, dry compressed air passes through the secondary side of the air–air heat exchanger, where it is reheated by the incoming warm air. This reheating prevents ‘sweating’ on the downstream pipe.

Our Superior Design includes the Following:

• Integrated heat exchanger
• The hot gas bypass control
• Compact user-friendly
• Microprocessor based controller
• LCD controller

Knitting Compressed Air Dryers is a vital part of the textile industry in all phases of spinning, weaving, loom, and knitting. Why do we need Air Dryers? Blow room to ring frame consist of a pneumatic system with solenoid valves and cylinders which are operated with compressed air. It is necessary that the air has to be clean and dry, in order to keep it away from rust formation and condensation which could corrode the smooth surfaces of the cylinder. Alternatively, the foreign particles could lock the solenoid valves orifice which may delay the movement of the cylinder which causes the alignment problem of the machine. One more important machine in spinning process is auto corner which has lots of solenoid valves and cylinders which are high speed through precisions. Hence the need to have the high degree of cleanliness in the air could be met only with desiccant dryer and submicron filters. In Airjet Weaving / Spinning: Compressed air blown through fine nozzles to transport the weft. Moisture and oil in the air block the nozzles. Nozzle replacement, production losses, fabric staining will also result in causing product rejections. Production of man-made raw materials for use in textiles also uses compressed air. One of the applications in the pneumatic transport of PVC, PTA . For the texturing process, the yarn is intermingled using a jet of air through the nozzle. Blockage due to oil, moisture will cause uneven intermingling and destroy the yarn and staining.
The latest technology in Desiccant Air Dryers offers total cleaning and drying solution for lubricated as well as non-lubricated Compressors. Coalescing filters (borosilicate micro glass fibers) assure maximum removal of oil and liquid moisture up to 0.3 microns. Compressed air at -40 deg C dew point.

Coldspell dryers remove the water content in the  Cylinder Applications Refrigeration Compressed Air Dryer  by cooling the air so that the water condenses. Coldspell dryers are available in a wide range of capacities. You should be able to find one in this range to meet your compressed air drying requirements. Should you have any special needs, please contact Trident.

Highlights:

• Large condenser facilitates operation under high ambient temperatures
• Anti-recycle feature protects compressor
• Low pressure drop across heat exchanger saves energy
• Designed to ISO 7183-2007 specifications
• Quality class ISO 8573-1:2010(E) Class 5

Coldspell Spells Benefits for you Convenience

• Because of the pre-cooling of the compressed air, it is possible to use a smaller refrigeration unit with reduced space requirements.
• The versatile control panel displays the dryer on/off status, drain open/closed status, refrigeration compressor status and drain valve status as well as the number of hours run, the air inlet temperature and the dew point temperature.
• Hot gas bypass control prevents freezing in the evaporator. The dew point is constant even with changing loads.

Economy:

• The pre-cooling also reduces the energy requirement of the dryer. Coldspell dryers are more economical than units without pre-cooling heat exchangers.
• Anti-recycling ensures that the gas pressure is equalized and the starting current of the machine is reduced.
• Operating costs are low because of the low pressure drop of the machine.

Consistent life-long Performance:

• Trident heat exchangers have no extended surfaces or sharp corners that collect dust, dirt or oil residues. The smooth, self-cleaning surfaces of their tubes ensure that the heat-transfer efficiency is maintained throughout the dryer’s life. Any contaminant is washed out with the condensed moisture at the demister.

Safety:

• The refrigeration dryers are rated for 16 bar ( g) operation for extra safety for you and your equipment.

Ergonomics:

• Because of the pre-cooling, it is possible to use a smaller refrigeration unit. Thus the space requirement of the dryer is less. Installation is made easy by the access to all connections from one side controlling the key component operation from the front panel.
