Description

1. Core Features & Advantages

① Multi-Dimensional Vacuum Dehydration

Utilizes water saturation curves and vacuum dehydration mechanism for rapid, thorough moisture removal, ensuring superior oil-water separation efficiency.

② Multi-Stage Deep Filtration

Combines multi-stage precision filtration to eliminate solid impurities and gases, restoring dielectric strength and meeting strict application requirements.

③ Standalone & Enclosed Design

Fully integrated unit requiring no affiliated equipment. Enclosed frame with mobile wheels allows flexible positioning; control panel ensures safe, automated operation.

④ High-Performance Vacuum System

Ultimate vacuum ≤2 Pa, operating vacuum ≤30 Pa, vacuum range -0.092~0.099 MPa. Includes vacuum evacuation, separation, and condensation systems to protect pumps and enhance drying.

⑤ Wide Capacity Range (ZJA Series)

Flow rates from 1800 to 30000 L/H (ZJA-30 to ZJA-500). Working temp 20–80℃, noise ≤70 dB(A), total power 35–275 kW.

⑥ Complete Composition

Heating system, oil conveying, vacuum separation, condensation, filtration, control, and vacuum evacuation systems integrated into one robust plant.
