1. Product introduction
Dry air generator, designed to provide high-purity dry air with a dew point of -40℃～-70℃ during installation and maintenance of large power equipment such as transformers and reactors, which can replace traditional hot oil circulation, nitrogen supplementation, vacuuming, etc. Drying method is more efficient, economical, safer and environmentally friendly. It comprehensively utilizes the respective advantages of refrigeration dryers, suction dryers, coalescing oil-water separation, and ultra-precision filtration, scientifically combines three drying and purification processes such as freezing, adsorption, and filtration, and uses reasonable pipeline connections and capacity matching. , So as to achieve the best economic operation and produce high-quality dry air with low dew point. And integrated design, PLC automatic control, automatic detection of various operating parameters, compact and reasonable structure, good drying effect, low regeneration gas consumption, long working life, good composite desiccant use effect, and three times longer life than ordinary adsorbents above. Using microcomputer program control, high efficiency, energy saving, safe and reliable.
2. Working principle
The atmosphere enters the air storage tank through the air compressor, most of the water is compressed and liquefied and discharged through the drain valve, and the air is dried for the first time; then it enters the refrigerated dryer, the water vapor is condensed into water, and the air is dried for the second time; Enter the adsorption dryer for the third drying, absorb the remaining trace moisture, and finally pass through the high-precision air filter to the equipment that needs dry gas.

Features
◆ Unique rapid regeneration technology of desiccant
Using rapid regeneration technology, the dry air generator can provide qualified dry air after running for 5-20 minutes. Really open and use, no need to wait.
◆ Low dew point of finished product
The core index to measure the dry air generator is the air supply dew point. The lower the dew point, the drier the air. The low dew point dry air will absorb the moisture in the transformer to improve the insulation performance of the transformer. The RC series of dry air integrates compression drying, freeze drying and adsorption drying, and adopts a multi-stage filtration system. Due to the use of the "strong composite molecular adsorbent" independently developed by our company, the dew point of the finished gas will quickly drop below -40°C regardless of the water content in the air.
◆ High efficiency filtration system
Using "gradual density" filtration technology, the highest filtration accuracy is 0.01 µm, and the solid particle retention rate is as high as 99.99%. The filtering accuracy of the primary filter is µm, the passing accuracy of the secondary filter is 0.1 µm, and the filtering accuracy of the tertiary filter is 0.01 µm.
◆ Thoroughly abandon the adsorbent for heating and regeneration
The adsorbent is specially made by our company. It adopts a powerful composite molecular agent and a fully automatic regeneration method without thermal pressure difference. There is no need to manually bake the adsorbent.
