Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a factory spanning 10,000–30,000 square meters and an annual export value between US$10 million and US$50 million. Our Stainless Steel MVR Evaporation Crystallization System with Mechanical Vapor Compressor, PLC Controlled, 800L/h is engineered to deliver high-efficiency evaporation and crystallization for industries ranging from chemical processing to wastewater treatment. By integrating advanced mechanical vapor recompression (MVR) technology and precise PLC automation, this system significantly reduces energy consumption while ensuring stable, continuous operation.
The core of this system lies in its ability to reuse vapor latent heat through compression, achieving up to 70–90% energy savings compared to traditional evaporators. Crafted from durable stainless steel, it resists corrosion and maintains product purity, making it ideal for sensitive solutions. The 800L/h capacity is designed for medium-scale production, offering flexibility for both standalone use and integration into larger processes.
Below we detail the key features, technical specifications, and operational advantages of this robust equipment.
Key Features & Technical Specifications
- Energy Efficient MVR Technology: Mechanical vapor compressor recycles latent heat; typical energy consumption is only 20–50 kWh per ton of water evaporated, depending on solution characteristics.
- PLC Controlled Automation: Siemens or equivalent PLC with HMI touchscreen for real-time monitoring of temperature, pressure, flow rate, and level. Remote control and data logging options available.
- Stainless Steel Construction: Entire system made from SS304 or SS316L (customizable), ensuring excellent corrosion resistance and longevity.
- Compact Modular Design: Pre-assembled skid-mounted structure reduces on-site installation time and footprint.
- Multiple Configuration Options: Can be designed for falling film, forced circulation, or scraped film evaporation to suit different feed viscosities and fouling tendencies.
- Safety & Compliance: Equipped with overpressure protection, emergency shutdown, and automatic fault diagnosis. System operates under vacuum to lower boiling temperature and reduce scaling.
- Adaptable to Various Industries: Suitable for brine concentration, zero liquid discharge (ZLD), chemical crystallization, pharmaceutical intermediates, food extracts, and more.

Frequently Asked Questions (FAQ)
Q1: What types of feed solutions can this MVR system handle?
A: It is suitable for aqueous solutions with low to medium viscosity, such as brine, chemical process streams, pharmaceutical intermediates, and food extracts. For highly viscous or scaling-prone liquids, we can modify the circulation type (forced circulation or scraped film).
Q2: How much energy does the MVR compressor consume?
A: Typically, the compressor consumes between 20–50 kWh per ton of water evaporated, depending on the boiling point elevation and required compression ratio. This is 5–10 times less than traditional multi-effect evaporators.
Q3: Can the PLC system integrate with existing plant DCS or SCADA?
A: Yes, the PLC supports common communication protocols such as Modbus, Profibus, or Ethernet IP. Integration can be customized upon request.
Q4: What is the minimum order quantity (MOQ) and delivery time?
A: MOQ is 1 set. Standard delivery time is 45–60 days after down payment, depending on customization complexity.
Q5: Do you provide on-site installation and commissioning?
A: Yes, we offer optional on-site technical support including installation supervision, commissioning, and operator training. Quotation can be provided separately.
Q6: How do you handle scaling or fouling in the evaporator?
A: We design the system with anti-scaling features such as low-temperature operation (under vacuum), proper flow velocity, and optional CIP (clean-in-place) nozzles. For severe scaling, a forced circulation design is recommended.
Q7: What spare parts should be kept in stock?
A: We recommend keeping spare gaskets, seals, and a set of sensors (temperature, pressure, level). A complete spare parts list is provided with the system manual.
Q8: Is the system compliant with international standards for export?
A: Yes, all our systems are manufactured under ISO9001 certified processes. Electrical components comply with IEC standards, and pressure vessels can be designed to ASME, PED, or GB standards as required.
