ACORE team designed DHP Dry Air Generator to provide high-purity dry air with a dew point as low as -55℃～-70℃ during installation and maintenance of large power equipment such as ultra-high voltage transformers, ultra-high voltage transformers and reactors. It can replace traditional drying methods such as hot oil circulation, nitrogen replenishment, and vacuuming, but it is more efficient, economical, safer and environmentally friendly. When installing and overhauling electrical equipment, it is not affected by changes in external climate conditions-even in rainy seasons, normal construction can be performed. When overnight construction is required, all flanges need to be sealed and filled with dry air to reach 0.02～0.03Mpa. The workload is greatly reduced, the construction period is shortened, and the quality of installation and maintenance is improved.

DHP Dry Air Generator is designed to provide high-purity dry air with a dew point as high as -40℃～-70℃ during installation and maintenance of large power equipment such as transformers and reactors. It can replace traditional hot oil circulation, supplement nitrogen, and vacuum. Other drying methods are more efficient, economical, safer and more environmentally friendly. The Transformer Dry Air Generator comprehensively utilizes the respective advantages of refrigeration dryers, suction dryers, coalescing oil-water separation, and ultra-precision filtration, and scientifically combines three drying and purification processes such as freezing, adsorption, and filtration, through reasonable pipeline connections and capacity matching , So as to achieve 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 life span three times longer than ordinary adsorbents the above. Using microcomputer program control, high efficiency, energy saving, safe and reliable.

DHP Dry Air Generator for Transformers has following features:

1.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. It can be used anytime without waiting.

2. Low dew point

The core index to measure the Transformer Dry Air Generator is the supply air 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 drying 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 be quickly reduced to below -40°C regardless of the water content in the air.

3.High efficiency and multi-stages filtration system

The Dry Air Generator for Transformers use "gradual density" filtration technology, the high filtration accuracy is 0.01μm, and the solid particle retention rate is as high as 99.99%. The filtration accuracy of the first-stage filter is μm, the passing accuracy of the second-stage filter is 0.1 μm, and the filtration accuracy of the third-stage filter is 0.01 μm.

4.Thoroughly discard the adsorbent and heatless regeneration. (User also can choose heater)

 The adsorbent of Dry Air Generator is specially made by ACORE. 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.
