As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been dedicated to providing high-quality industrial wastewater treatment solutions since 2015. Our 304 Stainless Steel MVR Evaporation and Crystallization Equipment with PLC Control represents a breakthrough in energy-efficient and reliable treatment technology. Designed for demanding industrial applications, this equipment combines mechanical vapor recompression (MVR) with precise automation to achieve outstanding concentration and crystallization results, reducing operational costs and environmental impact.
The core of our system is the MVR (Mechanical Vapor Recompression) technology, which recycles the latent heat of vaporization, drastically lowering energy consumption compared to traditional evaporation methods. The entire unit is constructed from 304 stainless steel, ensuring excellent corrosion resistance and longevity, even when handling aggressive wastewater streams. The integrated PLC control system allows for real-time monitoring, automatic adjustment of parameters, and remote operation, making it user-friendly and efficient.
Key Features & Technical Specifications
- Energy Efficiency: MVR technology reduces energy consumption by up to 70% compared to conventional multi-effect evaporators.
- High Corrosion Resistance: 304 stainless steel construction suitable for acidic, alkaline, and saline wastewater.
- Automated PLC Control: Touch-screen interface with programmable logic for precise temperature, pressure, and flow control.
- Compact Design: Space-saving footprint with integrated heat exchanger and separator.
- Easy Maintenance: Modular design allows quick access to key components like compressors and pumps.
- Customizable Capacity: Available in standard models from 1 m³/h to 50 m³/h, with larger capacities on request.

Frequently Asked Questions (FAQ)
- Q1: What is the working principle of MVR evaporation?
- A: MVR (Mechanical Vapor Recompression) uses a compressor to increase the pressure and temperature of vapor generated from the evaporation process. This compressed vapor is then used as the heating medium, recycling the latent heat and significantly reducing energy consumption.
- Q2: Can the equipment handle highly corrosive wastewater?
- A: Yes, the standard unit is made of 304 stainless steel, which offers good corrosion resistance for many industrial applications. For more aggressive chemicals, an optional upgrade to 316L stainless steel or other alloys is available.
- Q3: How does the PLC control improve operation?
- A: The PLC provides automatic control of temperature, pressure, feed rate, and discharge. It ensures stable operation, reduces manual intervention, and allows remote monitoring via Ethernet. The system also logs data for quality assurance.
- Q4: What is the typical energy saving compared to traditional evaporators?
- A: Our MVR system can save up to 70% of energy compared to conventional multi-effect evaporators, depending on the feed concentration and operating conditions.
- Q5: Is the equipment easy to install and maintain?
- A: Yes, the unit is pre-assembled and skid-mounted for easy installation. Maintenance points, such as the compressor and heat exchanger, are accessible. We provide detailed manuals and remote technical support.
- Q6: Can I customize the capacity or control system?
- A: Absolutely. We offer customizable capacity from 1 m³/h to 50 m³/h, and the PLC brand (e.g., Siemens, Allen-Bradley) can be specified according to your preference. Color and other options are also available.
- Q7: What after-sales service do you provide?
- A: We provide one-year warranty, spare parts supply, online troubleshooting, and optional on-site commissioning. Our team is available 24/7 for urgent inquiries.
- Q8: What certifications does your equipment comply with?
- A: Our manufacturing facility is certified under ISO9001, ISO14000, OHSAS18001, and other management systems. The equipment itself can be designed to meet CE, ASME, or other regional standards upon request.
