Coldspell refrigeration Air Dryers. Salient Features. Large condenser for high ambient temperatures Anti-recycle feature for compressor protection Low pressure drop across advanced heat exchangers saves energy The dryers have been designed for nominal standard inlet conditions as per ISO 7183 – 2007 Dryer quality class - ISO 8573 - 1 : 2010 (E) class -5- Coldspell Range Coldspell Range Applications Pharmaceutical Packaging Blow Molding Aeronautical valve testing Injection molding Chemical plants Furnace Manufacturing Unit Dairy industries Advantages Advanced Microprocessor based Bar Indicator or LCD display Inbuilt Anti Recycle timer Inbuilt Anti Freezing Displayed in Controller to measure the after cooler performance Displayed in Controller Replaceable Stainless steel Filter cartridge provided for effective removal of water with filtration of 25 microns.

At this temperature, water condenses into liquid droplets, which is removed from the air stream by a very efficient Demister Refrigeration Dryer - Coldspell Refrigeration Air Dryer Cycle Basic Refrigeration Cycle 1. Refrigerant Compressor Compresses Refrigerant gas and increases both its Pressure and Temperature 2. A Condenser removes Refrigerant heat and converts superheated Refrigerant to saturated liquid Refrigerant 3. An Expansion valve decreasesRefrigerant Pressure and Temperature 4. In the Evaporator it takes Heat from the hot fluid and cools it Refrigeration Dryer Operation Correction Factor How to select product ? THANK YOU
