Pharmaceutical Multi-effect Distilled Water Generator
The MOLECULAR Multi-effect Distiller is a GMP-compliant WFI Still and Pure Steam Generator designed for the pharmaceutical industry. It produces high-purity Water for Injection (WFI) and pharmaceutical-grade pure steam with outstanding energy efficiency and reliability.
Key Features of Our Multi-effect Distiller
Falling Film Technology
The system utilizes a falling film evaporation principle to ensure rapid heat transfer and effective removal of pyrogens, guaranteeing a sterile and high-purity product.
Modular Design
Its compact, modular structure allows for flexible installation and saves up to 30% of valuable floor space in your facility.
Dual-Plate Condenser
The innovative double tube plate design for condensers prevents potential cross-contamination, a critical feature for WFI production.
Automated Control
A fully automated PLC control system with a user-friendly interface monitors key parameters like TOC, conductivity, and temperature in real-time, simplifying operation and validation.
Advantages of Our Multi-effect WFI Generator
Exceptional Energy Efficiency: Our multi-effect still achieves over 30% energy savings by reusing secondary steam as a heat source, maximizing thermal cascade utilization. The 6-effect design, in particular, boosts energy efficiency by 40%.
GMP Compliance: The system is meticulously engineered to meet and exceed strict pharmacopoeia standards, including ChP, USP, and EP, guaranteeing its suitability for pharmaceutical applications.
High Water Quality: Compared to reverse osmosis systems, our WFI generator provides a more stable and higher-quality product, ensuring consistent purity for critical processes.
Integrated CIP/SIP: With a fully automated Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) process, the risk of cross-contamination is eliminated, and maintenance is simplified.

The working principle of multi-effect distilled water machine
A multi-effect distilled water machine produces high-purity water through a process of repeated evaporation and condensation. The core principle is multi-effect distillation, which efficiently reuses heat.
Raw water is first heated and boiled in the first effect using external steam. The resulting vapor, or primary steam, is then piped to the next effect to heat and boil more water. This cycle repeats through several effects, with each subsequent effect operating at a lower pressure and temperature. The final vapor is condensed to produce highly purified water. This design maximizes energy efficiency and is widely used in pharmaceutical and medical industries to produce water for injection.
Frequently Asked Questions
A multi-effect distiller uses a series of evaporators (effects) to reuse the latent heat from the previous effect's steam, making it significantly more energy-efficient than a single-effect distiller which only uses heat once.
Yes, our WFI still is designed and manufactured to meet or exceed international pharmacopoeia standards, including ChP (Chinese Pharmacopoeia), USP (US Pharmacopoeia), and EP (European Pharmacopoeia) for Water for Injection.
Our multi-effect still utilizes a thermal cascade process. Secondary steam from one effect becomes the heat source for the next, reducing the overall energy required. This process results in over 30% energy savings.
Yes, depending on the configuration, our system can be designed as a pure steam generator to produce pharmaceutical-grade pure steam that complies with EN285 standards for sterilization applications.
The system uses a falling film evaporation technology with a cyclone separator, which minimizes water droplet entrainment in the vapor, effectively removing impurities and pyrogens to produce highly pure and pyrogen-free WFI.
