Dry air generators provide ultra-clean compressed air for transformers and generators
Application
The REXON DAG series transformer dry air generator is used in the electrical and power industries to supply dry, clean, and moisture-free air for various transformer maintenance and protection applications. It is primarily used in:
Transformer Maintenance and Repair
Provides dry air during transformer oil changes, 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 maintenance.
High-voltage Transformers and Reactors
Ensures stable insulation conditions by preventing moisture absorption.
Protects insulation materials, extending the life of transformers.
Cable and Switchgear Drying
Used to dry power cables and high-voltage switchgear, preventing dielectric failures.
Transformer Manufacturing and Testing
Essential in transformer manufacturing and routine testing to ensure dry internal conditions.
APPLICATION:
DAG Transformer dry air generator is widely used in when the transformer and reactor etc large power equipment are been installed and recondition to produce the dry air. To ensure internal insulation of electrical equipment from moisture, maintenance personnel will not suffocate from lack of oxygen in the inner working of the device. It is more secure, more reliable, better economical and more convenient than bottled gas. When the oil filter works in the rainy days and humid environment, equipment box and oil will do the air drying to ensure improve the insulation of oil and reduce the moisture.
Functions
The REXON DAG series transformer dry air generator removes moisture from the ambient air and supplies high-purity dry air with controlled humidity levels. Its key functions include:
Moisture Removal
Reduces relative humidity to extremely low levels (< -70°C dew point).
Prevents moisture absorption into the transformer insulation and oil.
Insulation Protection
Protects windings, bushings, and insulation materials from moisture damage.
Improves dielectric strength and insulation performance.
Continuous Dry Air Supply
Provides a constant flow of dry air to transformer tanks, preventing condensation inside.
Maintains a stable internal transformer environment during open-tank operations.
Preserves Oil Purity
Prevents contamination of transformer oil by blocking the ingress of moisture.
Ensures stable dielectric properties of the oil.
Safety and Environmental Protection
Eliminates the need for nitrogen purges, reducing operating costs and environmental risks.
Improves worker safety by providing a non-toxic, breathable, dry air alternative.
