DHP Dry Air Generator is specially designed for transformers, reactors and other large power equipment in the installation and maintenance, it can supply high purity dry air with a dew point of up to -40 °C ~ -70 °C, can replace the traditional hot oil circulation, nitrogen supplementation, vacuum and other drying methods, and more efficient, economical, safe and environmentally friendly.

DHP Transformer Dry Air Generator comprehensively use the respective advantages of refrigeration dryer, suction dryer, coalescing oil-water separation and ultra-fine filtration, the three drying and purification processes such as freezing, adsorption and filtration are scientifically combined, and the optimal economic operation is achieved through reasonable pipeline connection and capacity matching, so as to achieve the best economic operation and produce high-quality and low dew point dry air. Dry Air Generator for Transformer adopts the integrated design, compact and reasonable structure, good drying effect, low regeneration gas consumption, long working life, good use effect of composite desiccant, life is more than three times longer than ordinary adsorbent. It adopts microcomputer program control, which is efficient, energy-saving, safe and reliable.

The Working principle of DHP Transformer Dry Air Generator

The gas is compressed by the air compressor and enters the gas storage tank, most of the water is compressed and liquefied and discharged through the sewage valve, and the air is dried for the first time; After entering the refrigeration dryer, the water vapor is condensed into water and discharged through the automatic drain valve, and the air is dried for the second time; Then it enters the adsorption dryer for a third drying, adsorbs the remaining trace amount of water, and finally passes through a high-precision air filter to the equipment that needs to dry the gas.

Features of Dry Air Generator

1. Unique desiccant rapid regeneration technology:

With rapid regeneration technology, the Dry air generator can provide qualified dry air after 5-20 minutes of operation. Truly go anywhere, no waiting.

2. Low dew point of finished gas:

The core indicator to measure the dry air generator is the air supply dew point, the lower the dew point, the drier the air. Low dew point dry air will absorb moisture within the transformer to improve the insulation performance of the transformer. DHP Dry Air Generator for Transformer integrates compression drying, freeze drying and adsorption drying, and adopts a multi-stage filtration system to make the outlet gas drier and purer.

3. High efficiency filtration system:

DHP Dry Air Generator use "asymptotic" filtration technology, the highest filtration accuracy is 0.01μm, and the solid particle retention rate is as high as 99.99%. The filtration accuracy of the primary filter is μm, the passing accuracy of the secondary filter is 0.1μm, and the filtration accuracy of the tertiary filter is 0.01μm.
