Dry Air Generator Parameters
Specifically designed to provide high-purity dry air with dew point as low as -40℃ to -70℃ for large power equipment such as transformers and reactors during installation and maintenance, it can replace traditional drying methods like hot oil circulation, nitrogen supplementation, and vacuum drying, and is more efficient, economical, safe, and environmentally friendly. It comprehensively utilizes the advantages of refrigerated dryers, desiccant dryers, coalescing oil-water separators, and ultra-fine filtration, scientifically combining freezing, adsorption, and filtration drying processes. Through reasonable pipeline connections and capacity matching, it achieves optimal economic operation and produces high-quality dry air with low dew point. With 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, and effective composite desiccant performance, its lifespan is more than three times longer than ordinary adsorbents. It adopts microcomputer program control, which is efficient, energy-saving, safe, and reliable.
Working Principle:
Atmospheric air enters the air storage tank through the air compressor, where most moisture is compressed and liquefied and discharged through the drain valve, achieving the first drying of the air. Then it enters the refrigerated dryer, where water vapor condenses into water, achieving the second drying. Subsequently, it enters the adsorption dryer for the third drying, adsorbing the remaining trace moisture, and finally passes through high-precision air filters before being delivered to equipment requiring dry air.
Product Features:
◆ Unique rapid regeneration technology for desiccant
With rapid regeneration technology, the dry air generator can provide qualified dry air after 5-20 minutes of operation. Truly ready to use without waiting.
◆ Low dew point of product gas
The core indicator for measuring the dry air generator is the supply dew point; the lower the dew point, the drier the air. Low dew point dry air will adsorb moisture inside the transformer to improve its insulation performance. The XL series dry air generator integrates compressed drying, refrigerated drying, and adsorption drying, and adopts a multi-stage filtration system. Due to the use of our company's independently developed "strong composite molecular adsorbent", no matter the moisture content in the air, the dew point of the product gas will quickly drop below -70℃.
◆ High-efficiency filtration system
Adopting "graded density" filtration technology, the highest filtration precision is 0.01μm, with a solid particle retention rate of up to 99.99%. The primary filter has a filtration precision of μm, the secondary filter has a precision of 0.1μm, and the tertiary filter has a precision of 0.01μm.
◆ Completely abandon heating regeneration of adsorbent
The adsorbent adopts a heatless pressure differential fully automatic regeneration method, completely eliminating the need for manual baking of the adsorbent
