As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to the design and production of high-efficiency evaporation and crystallization equipment since 2015. Our 316L SS Multi-effect Crystallizing Evaporator is engineered to meet the rigorous demands of industrial wastewater treatment and chemical processing, offering a robust solution for concentrating and crystallizing solutions with minimal energy consumption. With an annual export value exceeding US$10 million and a team of over 200 skilled professionals, we deliver reliable, automatic systems that help our global clients reduce operating costs and achieve sustainable production goals.
This evaporator features a multi-effect design that significantly reduces steam and energy usage compared to single-effect systems. The 316L stainless steel construction ensures excellent corrosion resistance, even when handling aggressive chemicals or high-chloride solutions. Equipped with fully automatic PLC control, the system operates with minimal manual intervention, providing consistent output of 1.2 tons per hour while maintaining precise temperature and pressure parameters. The 200kW power consumption is optimized through intelligent heat recovery, making this unit a cost-effective choice for continuous operation.
Key Features & Technical Specifications
- Material of Construction: 316L stainless steel for all wetted parts, ensuring long service life and resistance to pitting and crevice corrosion.
- Multi-effect Evaporation: Utilizes 3 to 5 effects (customizable) to maximize heat reuse, achieving up to 60% energy savings compared to traditional single-effect evaporators.
- Automatic Control: PLC-based control system with touch screen HMI, allowing real-time monitoring of temperature, pressure, flow rate, and liquid level. Remote monitoring and data logging are available as options.
- Energy Saving: Advanced heat pump integration and thermal vapor recompression (TVR) technology reduce overall power consumption to 200kW for the rated capacity.
- Crystallization Function: Designed to concentrate solutions beyond saturation, enabling recovery of solid crystals. Suitable for salts, organic compounds, and other industrial by-products.
- Output Capacity: Nominal capacity of 1.2 tons of evaporated water per hour, with flexibility to adjust based on feed concentration and product requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the typical payback period for this energy-saving evaporator?
A: With 60% energy savings, many clients recoup their investment within 1 to 2 years, depending on local energy costs and operating hours. Our team can provide a detailed ROI calculation based on your data. -
Q: Can it handle feed streams with high scaling potential or suspended solids?
A: Yes. The 316L SS construction resists scaling, and we can include features like scraped-surface heat exchangers or periodic CIP (clean-in-place) systems to manage fouling. Pre-filtration is recommended for heavy solids. -
Q: What utilities are required for operation?
A: Standard requirements include steam (or electric heating as an option), cooling water, compressed air for valves, and a power supply (380V/50Hz or customized). Our system integrates seamlessly with existing plant utilities. -
Q: Is the automatic control system compatible with SCADA or DCS?
A: Yes, the PLC supports Modbus RTU/TCP, Profibus, or other protocols. We can integrate with your existing DCS/SCADA for centralized monitoring. -
Q: What type of crystals can I expect?
A: The crystallizer is designed to produce free-flowing crystals with controllable size distribution. Typical products include sodium chloride, sodium sulfate, ammonium sulfate, and other common salts. Testing with your solution is recommended. -
Q: Do you offer a pilot test before purchase?
A: Absolutely. We have a pilot-scale multi-effect evaporator at our factory. We can run tests on your feed sample to verify design parameters and crystal quality. The test report will be provided free of charge for qualified inquiries. -
Q: What is the lead time and warranty period?
A: Standard lead time is 8–12 weeks after order confirmation, depending on customization. We offer a 12-month warranty against manufacturing defects, with extended plans available. Shipment is from Qingdao Port. -
Q: How do I maintain the equipment?
A: Routine maintenance includes inspecting seals, cleaning heat transfer surfaces, and checking PLC settings. We provide a detailed manual and offer remote support. Spare parts can be dispatched within 48 hours.
