How It Works
Understanding the coalescence dehydration technology
Coalescence Dehydration Principle
- Coalescing effect: Small water droplets merge into larger ones
- Demulsification: Breaks oil-water emulsion structure
- Gravity separation: Water settles and is automatically drained
Result: Water Content from 500ppm → Below 10ppm
Coalescence technology effectively handles oils that are difficult to separate with simple filtration.
Multi-stage Filtration Process
- Stage 1: Pre-filtration removes large particles (>20μm)
- Stage 2: Fine filtration captures micro-particles (1-10μm)
- Stage 3: Coalescence separates emulsified water
- Stage 4: Automatic water discharge
Result: Cleanliness Level NAS 4-6 Achieved
Meets the strict cleanliness requirements of precision hydraulic systems.
