Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. — a trusted manufacturer since 2015 with a 10,000-30,000 m² factory and annual exports exceeding US$10 million. Our Cocurrent Mechanical Vapor Recompression (MVR) Evaporator with Stainless Steel 304 Heat Exchanger represents a significant advancement in thermal separation technology. Designed for industries requiring efficient, low-energy concentration of liquids, this MVR evaporator leverages the principle of vapor recompression to dramatically reduce operational costs while maintaining high purity levels. Built with robust SS304 construction, it offers exceptional corrosion resistance and longevity, making it an ideal choice for demanding environments such as chemical processing, wastewater treatment, and food & beverage concentration.
At the core of this system is our proprietary cocurrent flow design, which ensures optimal heat transfer and minimizes fouling. The integrated Stainless Steel 304 heat exchanger provides excellent thermal conductivity and durability. Unlike traditional evaporators that rely on live steam or external heating sources, our MVR system uses a mechanical compressor to raise the pressure and temperature of the vapor, which is then recirculated as the heating medium. This closed-loop cycle cuts energy consumption by up to 70%, significantly lowering your carbon footprint and operating expenses.
Key Features & Technical Specifications
- Cocurrent Flow Configuration — Ensures uniform temperature distribution and reduces scaling, suitable for heat-sensitive materials.
- SS304 Heat Exchanger — Standard 304 stainless steel provides excellent resistance to oxidation and corrosion; optional upgrades to 316L are available upon request.
- High Energy Efficiency — Mechanical vapor recompression typically achieves a specific energy consumption of 8–20 kWh per ton of water evaporated, compared to 60–100 kWh for conventional systems.
- Compact Footprint — Integrated design occupies minimal floor space, ideal for retrofit projects.
- Automated Control — PLC-based system with HMI interface for precise monitoring of temperature, pressure, and flow rates.
- Easy Maintenance — Modular components and accessible heat exchanger bundles simplify cleaning and servicing.

Frequently Asked Questions (FAQ)
-
What is the difference between cocurrent and countercurrent flow in an MVR evaporator?
In cocurrent flow, both the feed liquid and vapor flow in the same direction. This reduces temperature gradients and minimizes scaling, especially for heat-sensitive or fouling-prone materials. Countercurrent designs can offer higher concentration factors but may require higher maintenance. -
Can the SS304 heat exchanger be upgraded to higher-grade stainless steel?
Yes, we offer options in SS316L, duplex stainless steel, or other corrosion-resistant alloys for applications involving chlorides or low pH. Please specify your feed composition for our recommendation. -
What is the typical payback period for your MVR evaporator?
Depending on local energy costs and operating hours, most clients achieve payback within 12–24 months due to the substantial reduction in steam or electricity consumption. -
What size MVR evaporator do you recommend for our 50 m³/day wastewater stream?
For 50 m³/day, a system with ~2,000 L/h evaporation capacity is typically suitable. However, the exact sizing depends on the feed concentration, desired final concentration, and heat sensitivity. Our engineering team will perform a detailed analysis. -
Does the system require a continuous supply of cooling water?
Unlike conventional evaporators with condensers that need cooling water, MVR systems reuse the compressed vapor as the heating medium. A small amount of cooling water may be needed for the compressor lubrication system, but the overall requirement is minimal. -
How do you handle scaling or fouling in the heat exchanger?
The cocurrent design inherently reduces scaling. Additionally, we offer an optional CIP (Clean-in-Place) system. For severe fouling, a mechanical cleaning port is accessible, and we can provide anti-scalant dosing recommendations. -
What certifications does your company hold?
Our company is certified under ISO9001, ISO14000, OHSAS18001, HACCP, SA8000, and others. We strictly follow these quality management systems during design, manufacturing, and testing. -
What is the lead time and shipping port?
Typical lead time is 4–8 weeks after order confirmation, depending on capacity. All equipment is shipped from Qingdao Port, China, with full export documentation and packing for sea freight.
