VACUUM DRYING OVEN Ф3200×4000MM FOR TRANSFORMER USE
Product Overview
The vacuum drying oven is designed according to vacuum drying principles and autoclave regulations, incorporating our extensive experience in electrical transformer equipment. This industrial-grade oven is primarily used for drying oil-immersed transformers, motors, capacitors, CTs and PTs. Its advanced design ensures uniform heating and efficient moisture removal while preventing core rusting.
Key Advantages
- Step-by-step drying method minimizes product deformation
- 30-45% faster drying time compared to conventional equipment
- Energy-efficient operation with thorough drying results
- Customizable dimensions and configurations available

Drying Process
Variable Pressure Drying Method
1. Preheat Stage
Low vacuum conditions with saturated vapor for uniform heating; intermittent vacuum to prevent condensation.
2. Dehydration Stage
Cycles of vacuum application and valve closure with heat supplementation to reach target temperature.
3. Final Drying Stage
High vacuum conditions to extract residual moisture until final quality check.
4. End Check
Measurement of vapor pressure rise rate with automatic shutdown when parameters are qualified.
