Product Introduction
The Multi-Effect water distiller converts purified water into Water for Injection through repeated evaporation, vapor separation and condensation.
Typical Process:
Purified Water Feed → Preheating → Multi-Effect Evaporation → Vapor-Liquid Separation → Condensation → Conductivity Check → WFI Discharge
Heat from one effect is reused by the next effect, improving thermal efficiency compared with single-effect distillation.
Main Features
1. Multi-Effect Distillation
Multiple evaporation stages reuse thermal energy for more efficient continuous WFI production.
2. Three-Stage Separation
Vapor-liquid separation helps reduce entrained droplets before final condensation.
Parts contacting feed water, pure steam and WFI use 316L stainless steel.
4. Non-Condensable Gas Removal
Automatic venting helps maintain stable evaporation and heat-transfer conditions.
5. PLC & PID Control
Temperature, pressure, conductivity and operating conditions can be centrally monitored.
6. Conductivity Monitoring
Product water quality can be continuously checked during operation.
7. Drainable Design
Sloped piping and low-point drainage help reduce retained water after operation.
8. Optional Pure Steam
Pure steam production can be added according to application requirements.
