Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015 and located in Qingdao, Shandong, China, is a leading manufacturer specializing in advanced environmental solutions. With a factory area spanning 10,000–30,000 square meters and a dedicated team of 201–300 employees, we export annually between US$10 million and US$50 million to markets worldwide including North America, Europe, Asia, Oceania, and Africa. Our PLC Controlled MVR Evaporation Crystallizer, rated at 380V, 15-30 kW, is engineered specifically for Zero Liquid Discharge (ZLD) applications. This system combines cutting-edge mechanical vapor recompression (MVR) technology with intelligent PLC automation, delivering energy-efficient, reliable crystallization and evaporation for industrial wastewater treatment. Discover a sustainable solution that reduces operating costs while meeting stringent environmental regulations.
Our MVR Evaporation Crystallizer utilizes a PLC-controlled compressor to recycle vapor energy, drastically lowering energy consumption compared to traditional thermal evaporators. The 380V power input and adjustable 15-30 kW motor allow flexible operation across various scales. The crystallizer is designed to treat high-salinity wastewater, recovering pure water and producing solid crystals, achieving true zero liquid discharge. Below are key technical specifications and features.

Product Features & Benefits
- Energy-Efficient MVR Technology: The mechanical vapor recompression system reuses the latent heat of vapor, reducing energy consumption by up to 70% compared to conventional evaporators. The 15-30 kW motor consumes minimal power while achieving high evaporation rates.
- Intelligent PLC Control: The PLC automates start-up, steady-state operation, shutdown, and alarm handling. Operators can adjust parameters via the HMI touchscreen, ensuring consistent performance and minimal manual intervention. Remote monitoring is available upon request.
- Zero Liquid Discharge (ZLD) Capability: The crystallizer separates wastewater into purified distillate (reusable or dischargeable) and dry solid crystals, leaving no liquid waste. Ideal for industries such as chemical, pharmaceutical, textile, mining, and power generation.
- Robust Construction: Built with high-quality stainless steel (SS304/SS316L) or duplex options, designed to withstand corrosive brines and high temperatures. The system is engineered for long service life and low maintenance.
- Flexible Power & Capacity: The 380V, 15-30 kW motor allows operation at different throughputs. The evaporator can be customized to handle feed concentrations from 1% to 25% TDS (total dissolved solids).
- Compact Footprint: Skid-mounted design reduces installation space and simplifies integration into existing treatment lines. Pre-assembled and tested before shipment.
- User-Friendly Maintenance: Easy access to compressor, heat exchanger, and crystallizer chamber for cleaning and servicing. PLC diagnostics provide real-time alerts for preventive maintenance.

Frequently Asked Questions (FAQ)
Q1: What is the typical payback period for this crystallizer?
A: The payback period depends on your feed volume, energy costs, and disposal savings. Many clients see returns within 12–24 months due to reduced energy consumption and elimination of liquid waste disposal fees.
Q2: Can the PLC control be integrated with existing SCADA systems?
A: Yes, our PLC supports Modbus RTU/TCP communication protocols. Integration with SCADA or remote monitoring systems is optional and can be configured upon request.
Q3: What is the maximum feed salinity the system can handle?
A: The system is designed for feed TDS up to 250,000 mg/L (25% salinity). For higher concentrations, pre-treatment or multi-stage configuration may be recommended. Our engineers will evaluate your water analysis to optimize the design.
Q4: How often does the compressor need maintenance?
A: Under normal operating conditions, the MVR compressor requires service every 8,000–10,000 hours. The PLC tracks runtime and provides maintenance reminders. Routine checks include oil level, vibration, and temperature.
Q5: Do you provide installation supervision or training?
A: Yes, we offer on-site installation guidance and training for your operators. Remote assistance is also available. Please inquire during the quotation phase.
Q6: What is the warranty period?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranties are available upon request.
Q7: Can I customize the capacity or size?
A: Absolutely. Our systems are modular and customizable. We can design units with evaporation capacities from 500 L/h to 10,000 L/h or more. Contact us with your process parameters.
Q8: Is the equipment certified for export to Europe or North America?
A: Our factory holds ISO9001 and other international certifications. Electrical components can be supplied with CE or UL marks as required. We will ensure compliance with local standards.
