Main Application

• Inflating dry air into transformer to assist safe transport;
• Testing of both leakage and normal pressure of transformer;
• Assembling or overhauling and air inflation of transformer's internal parts etc.

Technical Data of Dry Air Generator

Technical Features

Compression & Drying System:

Screw Compressor Option: The system can be equipped with a screw compressor (or utilize compressed air for cost efficiency).

Customizable Drying Technology:

Micro-heat or heatless regenerative adsorption dryers with dual-tower switching are available for tailored applications.Operates without a refrigeration dryer while achieving an outlet dew point temperature below -70°C, ensuring ultra-dry compressed air.

Multi-Stage Filtration System:

Pre-Filtration (Coarse Filter):First-stage protection to prevent dust from adhering to equipment components.Primary Fine Filtration (Inlet of Adsorption Dryer):Removes particles >0.1 μm and reduces oil content to ≤0.5 mg/m³.High-Precision Filtration (Outlet of Adsorption Dryer):Third-stage filter with 0.01 μm rating ensures oil concentration ≤0.01 ppm, meeting stringent transformer oil purity standards.Activated Carbon Final Filtration: Fourth-stage filter with activated carbon further reduces oil content to ≤0.03 mg/m³, eliminating residual contaminants and large particles.This multi-stage filtration system drastically minimizes particulate and oil contamination, guaranteeing optimal air quality for transformer applications.

Adjustable Pressure Control:

Outlet pressure range: 0.025 MPa to 0.75 MPa, adjustable based on process requirements to optimize performance.

Electrical Control System:

Siemens PLC (Programmable Logic Controller) for precise, automated, and reliable operation.

Precision Manufacturing & High-Quality Components:

Mechanical and electrical parts are precisely machined and sourced from internationally renowned brands, ensuring durability, reliability, and stable operational costs.
