As a leading manufacturer since 2015, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our state-of-the-art Multi-effect Crystallizing Evaporator, constructed from durable 304 Stainless Steel and engineered for continuous crystallization at a maximum operating temperature of 120°C. This equipment is designed to efficiently recover valuable solids from industrial wastewater, reduce effluent volume, and minimize disposal costs — all while maintaining high purity output. Our evaporator integrates advanced heat recovery technology to lower energy consumption, making it a sustainable choice for demanding separation processes.
The Multi-effect Crystallizing Evaporator operates on the principle of multiple evaporation stages, where vapor from one effect serves as heating medium for the next, drastically reducing steam usage. Combined with our proprietary continuous crystallization technology, it ensures uniform crystal growth and prevents scaling, leading to consistent product quality and extended operational cycles. Whether you're treating brine solutions, recovering salts, or concentrating chemicals, this system delivers reliable performance under continuous duty.
Key Product Features
- 304 Stainless Steel Construction — Corrosion-resistant, hygienic, and suitable for a wide range of acidic or alkaline feed materials.
- Multi-effect Design — Up to 4 effects available, achieving energy savings of 60-80% compared to single-effect evaporators.
- Continuous Crystallization — Patented internal circulation and seed crystal control ensures stable supersaturation, producing uniform crystals with narrow size distribution.
- Max Operating Temp 120°C — Allows processing of heat-sensitive materials while maintaining high evaporation rates.
- PLC Automatic Control — Touch-screen interface with real-time monitoring of temperature, pressure, flow rate, and crystal density.
- Compact Footprint — Vertical design minimizes floor space; modular options available for capacity expansion.
- Low Maintenance — Anti-scaling coating and easy-access inspection ports reduce downtime.
- Customizable Configurations — Options for vacuum operation, forced circulation, and different heating media (steam, thermal oil, electricity).

Frequently Asked Questions
-
Q: What feed concentrations can this evaporator handle?
A: The unit can process feed streams with solids content from 5% up to near saturation. For highly concentrated feeds, we recommend a pre-concentration stage or forced circulation design. -
Q: How often does the system need cleaning for scaling?
A: With continuous crystallization technology, scaling is minimized. Typical cleaning intervals range from 7 to 30 days depending on feed composition. An optional CIP (Clean-in-Place) system is available. -
Q: Can I process materials that are corrosive to 304 SS?
A: For highly corrosive media (e.g., concentrated chlorides or strong acids), we offer upgrades to 316L, duplex, or titanium. Please consult our engineers for material selection. -
Q: What is the typical delivery time?
A: Standard models can be shipped within 45-60 days after order confirmation. Custom configurations may require 60-90 days depending on complexity. -
Q: Do you provide installation and training?
A: Yes, we offer on-site supervision and training for your operators as part of our after-sales service. Remote support is also available via video call. -
Q: What is the warranty period?
A: Our standard warranty is 18 months from shipment or 12 months from installation, whichever comes first. Extended warranties are negotiable. -
Q: Can I send a sample for a pilot test?
A: Absolutely. We have a pilot-scale multi-effect crystallizing evaporator in our R&D center. Send a 50-liter sample for free feasibility testing and a detailed report. -
Q: How energy efficient is this system compared to mechanical vapor recompression (MVR)?
A: While MVR can achieve higher efficiency, our multi-effect design offers a lower capital cost and simpler operation. For applications with cheap steam available, multi-effect is often the preferred choice.
