Product Description

Transformer Dry Air Generator Provides Ultra Dry Purified Compressed Air DAG Series
 

Product Description

Application

REXON DAG Series Transformer Dry Air Generator 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:

Transformer Maintenance & Repair
Provides dry air during transformer oil change, overhaul, and maintenance.
Prevents atmospheric moisture from contaminating transformer insulation and oil.
Power Substations
Used in high-voltage substations to keep transformers moisture-free during assembly, transportation, and servicing.
High-Voltage Transformers & Reactors
Ensures stable insulation conditions by preventing moisture absorption.
Protects insulation materials, extending the lifespan of transformers.
Cable & Switchgear Drying
Used for drying power cables and high-voltage switchgear, preventing dielectric failures.
Transformer Factory & Testing
Essential in transformer manufacturing and routine testing to ensure dry internal conditions.

Functions
REXON DAG Series Transformer Dry Air Generator removes moisture from ambient air and supplies high-purity dry air with controlled humidity levels. Its key functions include:

Moisture Removal
Reduces the relative humidity of air to extremely low levels ( < -70°C dew point).
Prevents moisture absorption into transformer insulation and oil.
Insulation Protection
Protects windings, bushings, and insulation materials from moisture damage.
Enhances dielectric strength and insulation performance.
Continuous Dry Air Supply
Delivers a steady flow of dry air for transformer tanks, preventing condensation inside.
Keeps the transformer's internal environment stable during open-tank operations.
Oil Purity Preservation
Prevents contamination of transformer oil by blocking humidity ingress.
Ensures stable oil dielectric properties.
Safety & Environmental Protection
Eliminates the need for nitrogen purging, reducing operational costs and environmental risks.
Enhances worker safety by providing a non-toxic and breathable dry air alternative.

REXON Advantages
REXON Dry Air Generator 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 situation, and start drying itself. 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.
