MVR Forced Circulation Evaporator With Corrosion-Resistant Titanium Heat Exchanger
Product Spotlights
Qingdao Conqinphi Environmental Technology Group Co., Ltd. (founded 2015) is a leading manufacturer specializing in advanced evaporation and crystallization solutions. With a factory spanning 10,000–30,000 square meters, a dedicated team of 201–300 employees, and an annual export value of US$10–50 million, we bring global expertise to every project. Our MVR Forced Circulation Evaporator with Corrosion-Resistant Titanium Heat Exchanger is engineered for the most demanding industrial wastewater and chemical concentration applications. By combining mechanical vapor recompression (MVR) technology with a robust forced circulation design and a titanium heat exchanger, this system delivers unmatched energy efficiency, anti-scaling performance, and long-term reliability even in highly corrosive environments.
Key Features & Technical Advantages:
- MVR (Mechanical Vapor Recompression) Technology: Reduces steam consumption by 60–80% compared to traditional multi-effect evaporators. The compressor raises the vapor temperature, recycling latent heat for continuous evaporation.
- Forced Circulation Design: Maintains high flow velocity across the heat exchanger tubes, effectively preventing scaling and fouling – ideal for fluids with high suspended solids or tendency to crystallize.
- Titanium Heat Exchanger: Grade 2 or Grade 12 titanium offers exceptional resistance to chloride corrosion, acidic media, and brine solutions. Extends equipment lifespan by 3–5 times over stainless steel in aggressive conditions.
- Anti-Scaling & Self-Cleaning: The forced circulation loop minimizes deposit buildup, reducing maintenance downtime. Optional CIP (Clean-in-Place) system available.
- Fully Automated Control: PLC-based system with HMI touchscreen enables real-time monitoring of temperature, pressure, flow, and concentration. Remote access and data logging are customizable.
- Energy Recovery Efficiency: Low specific energy consumption – typical thermal energy usage below 50 kWh per ton of water evaporated (depending on feed characteristics).
- Modular Design: Pre-assembled skids for quick on-site installation. Capacity can be scaled from 1 m³/h to over 100 m³/h per unit.
- Material Certification: All titanium components come with material test certificates (MTC) as per ASTM B265. Welders are qualified to ASME Section IX.

Benefits for Your Process:
- Drastically reduce operating costs – lower steam and electricity consumption thanks to MVR heat recovery.
- Handle aggressive wastewater – titanium resists chlorides, fluorides, acidic streams (pH 1–12) with minimal corrosion rate.
- Achieve high concentration ratios – up to 30% solids or near saturation without scaling issues.
- Minimize downtime – forced circulation design and easy-access heat exchanger bundle simplify cleaning and inspection.
- Compliance with environmental regulations – zero liquid discharge (ZLD) capability when combined with crystallizer.
- Customization – we tailor the evaporator to your feed composition, target concentration, and site utilities.

Frequently Asked Questions (FAQ)
-
What types of feed streams can this evaporator treat?
It is ideal for high-salinity wastewater, chemical process liquors, landfill leachate, brine, and any corrosive streams containing chlorides or other halides. The titanium heat exchanger makes it especially suitable for acidic or chloride-rich environments. -
Why is a forced circulation design better than falling film for scaling fluids?
Forced circulation maintains a high velocity (>2 m/s) across the heat transfer surface, which hinders scale deposition and crystal adhesion. Falling film evaporators are prone to fouling when solids exceed 5–10%. Forced circulation is the preferred choice for high-concentration or scaling-prone applications. -
How energy-efficient is this MVR system?
Typical specific energy consumption ranges from 30 to 60 kWh per ton of water evaporated, depending on the boiling point elevation and temperature lift. This is 70–80% less steam consumption compared to a single-effect evaporator. -
What maintenance is required for the titanium heat exchanger?
The titanium bundle is highly resistant to corrosion, but periodic cleaning may be needed for scales (e.g., calcium sulfate). We recommend a CIP (clean-in-place) system. The forced circulation loop also reduces cleaning frequency. -
Can you customize the capacity or materials?
Absolutely. We offer complete customization – capacity, heat exchanger area, compressor type, instrumentation, and wetted materials (e.g., Hastelloy, Duplex SS) are all adjustable based on your process requirements. -
What certifications do your products have?
We hold ISO9001, ISO14000, OHSAS18001, HACCP, SA8000, among others. Our manufacturing follows ASME standards (upon request) and we provide full documentation including material certificates, weld maps, and pressure test reports. -
What is the typical lead time and shipping port?
Lead time depends on size and complexity, generally 8–16 weeks. Products are shipped from Qingdao Port (China). We also offer supervision of installation and commissioning if needed. -
How do you ensure the quality of the titanium material?
All titanium plates and tubes are sourced from certified suppliers (e.g., ASTM B265 Grade 2/12). Incoming material is inspected, and each heat exchanger is hydrostatically tested. We provide traceable MTCs.
