Refrigeration Compressed Air Dryer - Coldspell

Product catalog summary

Overview: The Coldspell refrigeration compressed air dryer is designed to operate efficiently in high ambient temperatures with features such as a large condenser and an anti-recycle feature for compressor protection. It ensures low pressure drop across advanced heat exchangers, saving energy. The dryers are compliant with ISO 7183 - 2007 for nominal standard inlet conditions and meet ISO 8573 - 1 : 2010 (E) class -5- for dryer quality.

Specifications: The dryers are available in various models with different capacities, ranging from 20 scfm to 2000 scfm. They use refrigerants R134a and R407C, depending on the model. The maximum working pressure is 16 bar, and all models come with an air-cooled condenser by default, with a water-cooled option available upon request.

Ordering Instructions: To select the appropriate model, consider the inlet flow, working pressure, inlet temperature, and ambient temperature. Use correction factors for air inlet temperature, ambient temperature, and inlet pressure to determine the required dryer capacity. For example, for an inlet flow of 100 scfm, working pressure of 5 Kg/cm², inlet temperature of 45°C, and ambient temperature of 38°C, the required dryer capacity is 119 scfm, leading to the selection of the Coldspell 150 model.

Correction Factors: Tables are provided to adjust for air inlet temperature, ambient temperature, and inlet pressure, ensuring accurate capacity calculations.

Product Range: In addition to the Coldspell dryers, the company offers timer-based and level-sensing auto drain valves, desiccant dryers (heatless and heated), and oxygen & nitrogen generators. The Coldspell models vary in display type, from wheel type indicators to advanced LCD display controllers.
