The role of cold dryer and suction dryer

In the field of compressed air treatment, cold dryer and suction dryer as the key post-processing equipment, each play an irreplaceable role. The water-lubricated screw air compressor produced by Shanghai Granklin Group has become a bright pearl in this field with its unique environmental protection and high efficiency characteristics.

Cold dryer, as the name suggests, through the principle of freezing and dehumidification, the moisture in the compressed air is condensed and separated to achieve the purpose of drying. Its working principle is simple and efficient, but limited by its technical characteristics, the dew point temperature is usually maintained at 2~10 ℃, suitable for general industrial needs.

In contrast, the suction dryer uses a more advanced pressure swing adsorption technology. The saturated compressed air from the upstream is fully contacted with the desiccant in the drying machine, and most of the moisture is absorbed in it, so as to realize the deep drying. The dew point temperature of the suction dryer can be as low as -20 ℃, and the water removal effect is far better than that of the cold dryer, which is especially suitable for occasions with extremely high quality requirements for compressed air.

As the core equipment of compressed air supply, the water lubricated screw air compressor produced by granklin group is perfectly complementary to the cold dryer and suction dryer with its zero emission and pollution-free characteristics. Water lubrication technology not only avoids the pollution problems that traditional lubricants may bring, but also significantly improves the operating efficiency and stability of the compressor. When used in conjunction with a cold dryer or suction dryer, it can ensure that the output air reaches a higher standard of dryness and purity.

To sum up, cold dryers and suction dryers perform their respective duties in compressed air treatment, while Granklin Group's water-lubricated screw air compressors have injected new vitality into this field with their excellent performance and environmental protection advantages. The three complement each other and jointly promote the continuous progress and development of compressed air treatment technology.
