Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 with a 10,000-30,000 m² factory and over 200 skilled employees, proudly presents our SS316L Multi-effect Evaporation Crystallization Equipment. Designed for industrial-grade performance, this system combines high-grade stainless steel construction with advanced PLC automatic control, delivering reliable and energy-efficient evaporation and crystallization for demanding applications such as wastewater treatment, chemical concentration, and brine recovery. With a flexible capacity range of 500 to 5,000 L per hour, it adapts seamlessly to varying production scales while minimizing operational costs.
Product Highlights & Technical Specifications
- Material Excellence: All wetted parts are made from SS316L stainless steel, offering excellent corrosion resistance against acids, alkalis, and chlorides, ensuring long service life even under harsh conditions.
- Energy-Efficient Multi-effect Design: The multi-effect evaporation principle reuses vapor from one effect as heating medium for the next, achieving steam savings of up to 70% compared to single-effect systems. Typical steam consumption ranges from 0.2 to 0.4 kg steam per kg of water evaporated, depending on the number of effects (e.g., 3-effects, 4-effects).
- PLC Automatic Control: Equipped with a Siemens or equivalent PLC system, the equipment automatically monitors and adjusts parameters such as temperature, pressure, liquid level, and flow rate. Touch-screen interface provides intuitive operation, real-time data display, and alarm functions, reducing manual intervention by over 80%.
- Capacity Flexibility: The standard model covers 500-5,000 L/h water evaporation capacity. Custom designs are available for higher or lower capacities upon request. The system can handle feed concentrations from 1% to 35% total dissolved solids (TDS).
- Compact Footprint: Multi-effect design significantly reduces floor space requirements. A typical 2,000 L/h system occupies approximately 80 m², making it ideal for both greenfield and retrofit projects.
- Easy Maintenance: Modular construction allows quick access to each effect for inspection and cleaning. The SS316L surface is smooth and resistant to scaling, reducing maintenance frequency.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of the SS316L material in this equipment?
A: SS316L offers superior corrosion resistance to chlorides and acids, making it ideal for treating high-salinity wastewater, acidic streams, and brine solutions. It also meets hygienic standards required in pharmaceutical and food industries. -
Q: Can the PLC system be integrated with existing plant DCS or SCADA?
A: Yes, the PLC supports common communication protocols such as Modbus, Profibus, and Ethernet/IP, allowing seamless integration with your existing control network. We can also customize the HMI interface per your requirements. -
Q: What is the typical energy consumption for a 2000 L/h system?
A: For a 3-effect system, the steam consumption is approximately 0.35 kg steam per kg of water evaporated, and the electrical consumption is around 5-10 kW for pumps and controls. This results in up to 70% energy savings compared to single-effect evaporators. -
Q: How often does the equipment need maintenance?
A: Routine inspection every 1-2 months is recommended, focusing on seals, pumps, and control components. Major cleaning may be required every 6-12 months depending on scaling tendency. The SS316L surface minimizes scaling, extending intervals. -
Q: What is the minimum space required for installation?
A: The footprint varies with capacity. For a 1000 L/h unit, approximately 50 m² is needed. Our engineering team will provide a detailed layout drawing after reviewing your site conditions. -
Q: Do you offer training for operators?
A: Yes, we provide comprehensive training at your site or in our factory, including PLC operation, troubleshooting, and preventive maintenance. Manuals and video tutorials are also supplied. -
Q: What kind of after-sales warranty do you provide?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty options are available upon request. We also maintain a global network of service partners for rapid support.
