Widely applicable for supplying dry air during the maintenance of large power equipment such as transformers and reactors. The provided dry air ensures that the internal insulation of power equipment does not become damp, and maintenance personnel will not suffer from hypoxia or suffocation when working inside the equipment. It is safer, more reliable, economical, and convenient than using nitrogen. When using the dry air generator for equipment maintenance, it is not affected by changes in external weather conditions, especially for overnight operations. Simply seal all flanges and fill with dry air at 0.1-0.3 MPa, and transformers, reactors, etc. without oil injection will not become damp. This reduces the workload of daily oil extraction and injection, achieving the effect of shortening maintenance cycles and improving maintenance quality. During oil filtration, the equipment box and oil can be dried by filling with dry air. When filtering oil in rainy or humid environments, it ensures improved oil insulation and reduced moisture. After connecting an oil depot (oil tank) to the dry air generator, it can ensure that stored spare oil remains in a qualified state for a long time, ready for emergency projects at any time. It can also be used for other warehouses, library and archive rooms, production sites, etc. that require a certain amount of dry air.
Air Dry Generator Features
● Adopts twin-screw air compressor and low-temperature condensation dewatering technology.
● Compact size, light weight, simple operation, energy saving, safe and reliable use.
● Integrates the advantages of refrigerated dryers, adsorption dryers, and ultra-precision filters to scientifically combine and produce high-quality dry air with low dew point.
● This machine has an integrated design, optional PLC automatic control, automatic detection of various operating parameters, compact and reasonable structure, good drying effect, low regeneration gas consumption, long working life, effective composite desiccant use, and a lifespan more than three times longer than ordinary adsorbents.
● Regenerative adsorption dewatering technology, high-precision coalescing oil removal and dehydration filter elements, and 0.01μm precision filters ensure air cleanliness, with simple operation, energy saving, and safety and reliability.
The dry air generator is specially designed to provide high-purity dry air with a dew point as low as -55℃ to -70℃ during the 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 supplementation, and vacuum drying, but is more efficient, economical, safe, and environmentally friendly.
Air Dry Generator during power equipment installation and maintenance is not affected by changes in external weather conditions - even in rainy seasons, construction can proceed normally. When overnight construction is required, simply seal all flanges and fill with dry air to 0.02-0.03 MPa. This greatly reduces workload, achieving the effect of shortening construction periods and improving installation and maintenance quality.
Product Functions:
♦ Removes moisture from the air. The dew point of the treated air can be lower than -80℃ at the limit.
♦ Removes particulate matter from the air.
♦ Replaces nitrogen drying or hot oil circulation drying during overnight transformer construction.
♦Provides dry air during transformer installation and maintenance to ensure the transformer remains dry.
♦ Fills gas cylinders with dry air.
