Typical Specifications of Refrigerated Dryers
The maximum inlet temperature of refrigerated dryers can reach 60°C or 80°C. The working pressure range is usually 0.6-1.0MPa or 0.6-1.6MPa, and the pressure dew point range is 2°C~10°C or 3~10°C. The cooling method is mainly air cooling. Commonly used refrigerants include R410A, R134a and R22. The pressure loss generally does not exceed 3% of the design pressure or 0.02MPa .
Typical Specifications of Adsorption Dryers
The throughput of adsorption dryers can reach 300-3560 l/s, and the pressure dew point can be as low as -20°C or -70°C. According to the different regeneration methods of adsorbents, they can be divided into heatless regeneration, micro-heat regeneration, forced-air hot regeneration and compression hot regeneration . Selection Criteria The selection criteria for compressed air dryers include the maximum air flow rate, which needs to be determined based on the actual needs of the air-using equipment and the exhaust volume of the air compressor. The required pressure dew point needs to be combined with the actual production process and the equipment's requirements for compressed air quality. The inlet air pressure needs to match the exhaust pressure of the air compressor. The inlet air temperature and ambient air temperature (cooling water inlet temperature for water-cooled condensers) have a significant impact on the performance of the dryer. The installation environment of the dryer needs to consider factors such as space, corrosiveness, and noise. The reliability and stability of the equipment are among the factors that need to be considered when selecting the model. Energy consumption costs need to be comprehensively considered in terms of equipment energy consumption. Maintenance costs include regular maintenance and parts replacement. Budget constraints need to be comprehensively considered in terms of procurement and operating costs [8].
