• Qualified feed water is pressurized by a multistage pump and enters the pipeline condenser, where waste heat is used to preheat the water. The feed water then passes through the second preheater and first preheater before entering the evaporator.
• Inside the evaporator, the feed water is distributed into the heating tubes and flows along the tube wall as a thin film. Industrial steam heats and vaporizes the water, generating secondary steam that contains water droplets.
• The secondary steam enters the steam-water separation device from the lower part of the evaporation chamber. Through falling-film evaporation, gravity separation, and spiral-flow separation, water droplets are removed and ultra-pure steam is produced for pharmaceutical sterilization and disinfection use.

• Double Tube Sheet Design: The evaporator and separator can adopt a double tube sheet structure, helping reduce cross-contamination risks and support hygienic system design.
• Three-Stage Separation: Falling-film evaporation, gravity separation, and spiral-flow separation help remove water droplets and support stable pure steam quality.
• SS316L Contact Parts: All parts in contact with feed water, pure steam, and pure steam condensate are made of SS316L to support hygienic pharmaceutical production.
• Efficient Insulation: The evaporator, preheater, and condenser use aluminum silicate needle-punched blanket insulation, helping reduce heat loss and improve thermal stability.
• Polished Stainless Steel Surfaces: Internal and external surfaces can be electrochemically polished to maintain stainless steel smoothness, while the external surface can also be sandblasted.
• Energy-Saving Operation: The evaporator and separator form a large communicating structure that helps use heat more fully. The system can quickly reach maximum production capacity from standby, while liquid level control and condensate preheating help reduce energy consumption.
• Reduced Welding Design: Stainless steel pipes are bent directly where possible to reduce welding points, helping improve hygienic design and long-term reliability.
• Controlled Welding Quality: Pipeline and fitting welds can use argon-protected automatic welding, followed by electrochemical polishing, helping maintain weld quality and cleanability.
• Verification Support: Endoscopic inspection photos, weld maps, pressure test reports, pickling and passivation reports, and system design documents can be provided to support project validation.
• Automatic Control: The HMI + PLC control system supports fully automatic operation, simple interface use, multiple communication modes, and at least three user authority levels.
• Online Monitoring: Conductivity, temperature, flow, and other key parameters can be monitored online, with optional paperless or paper recorders for data recording and printing.
• Compliance-Ready Data Control: Electronic signatures, electronic records, and audit trail functions can be configured to support GAMP 5 and 21 CFR Part 11 requirements.
• Project-Specific Configuration: The Pure Steam Generator (PSG) can be configured according to your sterilization demand, clean utility layout, and validation requirements. Contact our team to discuss a suitable pure steam solution for your facility.
