AD-120 Dry Air Generator

AD-120 Dry Air Generator

AD-120 Dry Air Generator is a critical first-line defense in power equipment maintenance, delivering ultra-dry air with a dew point as low as -70°C. While this system is essential for creating and maintaining a moisture-free environment inside transformer tanks during installation and storage, comprehensive maintenance requires a holistic approach. For substation maintenance or repairs work, except the AD-120 Dry Air Generator, we also recommend you WEINENG ZYD Double-Stage High Vacuum Transformer Oil Purifier and VPS Transformer Evacuation System as a powerful assistant in your transformer installtion or maintenance business.

• Exceptional Drying Performance: Achieves an extremely low pressure dew point of -70°C, ensuring the delivery of ultra-dry air to effectively safeguard sensitive equipment from moisture ingress.
• Robust Power & High Flow Rate: Operates on a 25KW, three-phase 380V/50Hz power supply and delivers a substantial gas supply volume of ≥200m³/h, enabling efficient and continuous operation for large-scale applications.
• Wide & Adjustable Pressure Range: Functions within a working pressure of 0.6~1.0MPa and allows for precise adjustment of air supply pressure from 0.01-0.1MPa, offering flexibility to meet specific on-site process requirements.
• Safe & Economical Alternative: Eliminates the risks and ongoing costs associated with nitrogen cylinders. It provides a breathable, safe environment for workers and is a more cost-effective solution for extended operations.

• Prevent Moisture Ingress During Critical Interventions: Keep the internal structure of your transformer bone-dry during assembly, repair, or when the cover is opened, which is a crucial step before the final vacuum and oil filling process.
• Create a Synergistic Maintenance Workflow: Use the AD-120 Dry Air Generator to control the environment, then use our VPS Vacuum Evacuation System to deeply dry the tank walls and solid insulation, and finally use our ZYD Transformer Oil Purifier to ensure the insulating oil is perfectly clean and dry before injection.
• Achieve Total Moisture Elimination for Long-Term Reliability: This integrated strategy attacks moisture from every angle—the tank atmosphere, the cellulose insulation, and the transformer oil itself—guaranteeing maximum dielectric strength and operational lifespan.
