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.
Introduction of Workflow
After compressed (or using existing compressed air), air passesthrough two levels of filters and then enter into dry machine to keep airdew point temperature under -70℃, finally gothrough another two levels of fine filters to obtain dry and clean gas.
