Automatic Transformer Dry Air Generator Set 200M³/Hour Provides Ultra Dry Purified Compressed Air

REXON Transformer Dry Air Generator DAG-200(200m³/hr) is used in power and electrical industries to supply moisture-free, clean, and dry air for various transformer maintenance and protection applications. It is mainly applied in:
1. Transformer Maintenance & Repair
Provides dry air during transformer oil change, overhaul, and maintenance.
Prevents atmospheric moisture from contaminating transformer insulation and oil.
2. Power Substations
Used in high-voltage substations to keep transformers moisture-free during assembly, transportation, and servicing.

3. High-Voltage Transformers & Reactors
Ensures stable insulation conditions by preventing moisture absorption.
Protects insulation materials, extending the lifespan of transformers.

4. Cable & Switchgear Drying
Used for drying power cables and high-voltage switchgear, preventing dielectric failures.
5. Transformer Factory & Testing
Essential in transformer manufacturing and routine testing to ensure dry internal conditions.

1. Adopts a low-pressure, condensation technique, with the merits of small dimension, light weight, easy operation, energy saving, and reliability.

2. With a double screw air compressor, low temperature condensation to water technology, etc.

3. Comprehensive utilization of dryer, blot machine, ultra precision filter merits, such as scientific combination, produces high quality, low dew point of the dry air.

4. The native integration design, compact structure, and reasonable, good drying effect, low gas consumption, long working life, composite desiccant use effect is good, service life of ordinary adsorbents is extended more than three times.

5. Regenerative adsorption dehydration technology, the high accuracy coalescence dehydration, 0.01μm precision filters to ensure cleanliness.

REXON Dry Air Generator DAG-200 uses an air compression system, refrigerated air drying system, adsorption drying system, air purification system and PLC control system. With the unique design of the Double-Tank, it can work continuously without stopping. The two tanks will change automatically when the moisture reaches the set level, and start drying themselves. Compared with the traditional nitrogen-filling way, a dry air generator is more reliable, safe and economical, shortens the maintenance period and greatly improves the efficiency of maintenance quality.
