Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – your trusted manufacturer of high-efficiency evaporation systems since 2015. Our High-Efficiency Vacuum Falling Film MVR Evaporator is engineered specifically for demanding wastewater treatment applications, combining advanced mechanical vapor recompression (MVR) technology with a falling film design to achieve exceptional energy savings and operational stability. As a factory-direct supplier with a 10,000–30,000 m² facility and an annual export value exceeding US$10 million, we deliver premium quality at competitive prices – directly to your doorstep.
This evaporator operates under vacuum conditions to lower the boiling point of the liquid, minimizing thermal degradation and scaling. The falling film configuration ensures a thin, uniform liquid layer across the heat transfer tubes, maximizing heat transfer efficiency and reducing residence time. Combined with MVR technology that recycles vapor heat, our system can reduce energy consumption by up to 70% compared to traditional single-effect evaporators. Whether you're treating high-salinity wastewater, chemical process streams, or landfill leachate, this unit offers reliable, continuous performance.
Key Features & Technical Advantages
- Energy-Efficient MVR Technology – Mechanical vapor recompression reuses latent heat of vapor, cutting steam consumption by 50–70%.
- Vacuum Operation – Evaporation temperature as low as 40°C, ideal for heat-sensitive or corrosive fluids.
- Falling Film Design – High heat transfer coefficient (up to 3000 W/m²·K) with minimal fouling.
- Modular & Scalable – Customizable capacity from 500 L/h to 50,000 L/h; multiple units can be paralleled for higher throughput.
- Automated Control System – PLC + HMI touchscreen for real-time monitoring of temperature, vacuum, flow, and concentrate density.
- Corrosion-Resistant Materials – Standard 316L stainless steel; options for titanium, duplex SS for aggressive media.
- Low Maintenance – CIP (clean-in-place) design and easy access to tube bundles reduce downtime.
- Environmentally Friendly – Closed-loop operation reduces effluent volume and recovers valuable condensate for reuse.

Frequently Asked Questions
-
Q: What types of wastewater can this evaporator handle?
A: It is suitable for high-salinity brines, chemical process effluents, pharmaceutical waste, landfill leachate, and many other industrial streams. We recommend a lab test or pilot trial for specific applications. -
Q: How does the MVR system save energy compared to a conventional evaporator?
A: MVR recompresses the vapor produced, raising its temperature so it can be reused as heating steam. This reduces steam consumption by 50–70% and eliminates the need for a cooling tower in many cases. -
Q: Is the product customizable for different capacities?
A: Absolutely. We design each unit based on your flow rate, feed composition, and target concentration. Capacity ranges from 500 L/h to 50,000 L/h per unit. -
Q: What certifications does your company hold?
A: Our company is certified under ISO9001, ISO14001, OHSAS18001, HACCP, and several other quality management standards. Specific product certifications can be provided upon request. -
Q: What is the delivery time for a standard unit?
A: Typical lead time is 30–60 working days, depending on complexity and production schedule. Rush orders may be accommodated. -
Q: Do you provide after-sales service and spare parts?
A: Yes, we offer a one-year warranty, lifetime technical support, and a full inventory of spare parts. Our team can also assist with installation and commissioning via video or on-site visit. -
Q: How does the falling film design prevent scaling?
A: The thin film and low residence time reduce the chance of scale formation. Additionally, the vacuum operation lowers evaporation temperature, minimizing salt precipitation. An optional CIP system is available for routine cleaning. -
Q: Can I get a sample trial or pilot test before purchasing?
A: Yes, we have pilot-scale MVR evaporators available for testing with your actual wastewater. Contact us to schedule a trial.
