MVR Forced Circulation Evaporator Featuring High-Efficiency Centrifugal Compressor
Product Spotlights
Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents the MVR Forced Circulation Evaporator Featuring High-Efficiency Centrifugal Compressor – a cutting-edge solution designed to significantly reduce energy consumption while achieving maximum evaporation performance. As a manufacturer with over 8 years of experience (established in 2015) and a factory spanning 10,000-30,000 m², we combine advanced engineering with strict quality control to deliver reliable equipment for global industries. This evaporator utilizes mechanical vapor recompression (MVR) technology to recycle latent heat, making it an ideal choice for concentrating solutions in chemical, pharmaceutical, food, and wastewater treatment processes. Our unit is engineered to operate with low operational costs and minimal environmental impact, ensuring your production meets both economic and sustainability goals.
Key Features & Technical Specifications
- High-Efficiency Centrifugal Compressor: The core component is a custom-designed centrifugal compressor that delivers a pressure rise of 0.05–0.5 bar with an isentropic efficiency above 85%. This ensures stable vapor recompression even under fluctuating feed conditions.
- Forced Circulation Design: The forced circulation loop prevents scaling and fouling, allowing the evaporator to handle high-viscosity, high-concentration, and crystal-prone liquids. Circulation velocity is adjustable between 1.5–3.0 m/s via a dedicated circulation pump.
- Energy Savings: MVR technology typically reduces energy consumption by 60–80% compared to traditional multi-effect evaporators. The system requires only electrical energy for the compressor and pumps, with minimal steam or cooling water demand.
- Compact & Modular Construction: The evaporator is supplied as a pre-assembled skid-mounted unit, simplifying on-site installation. Modular design allows capacity expansion from 1 ton/h to over 100 tons/h.
- PLC Automatic Control: The control system features a touch-screen interface for real-time monitoring of temperature, pressure, flow rate, and compressor speed. Remote monitoring and data logging options are available.
- Corrosion-Resistant Materials: Standard wetted parts are made of SS316L or SS304, with options for duplex stainless steel, titanium, or Hastelloy for aggressive media.
- Customizable Operating Parameters: Evaporation temperature can be set between 50–120°C, and the system can handle feed concentrations from 5% to 60% (or higher with special design).

Benefits to Your Operation
- Lower Energy Costs: With MVR technology, you can reduce steam consumption by up to 80%, translating into substantial savings on fuel or electricity bills.
- Reduced Footprint: The forced circulation design achieves high heat transfer coefficients (up to 1500 W/m²·K), allowing a smaller heat exchanger area and compact overall size.
- Enhanced Product Quality: Gentle evaporation at lower temperatures minimizes thermal degradation of heat-sensitive products, preserving flavor, color, and nutritional value in food applications.
- Minimal Maintenance: The absence of steam ejectors and the robust compressor design reduce moving parts, leading to longer service intervals and lower maintenance costs.
- Environmental Compliance: The closed-loop system reduces wastewater discharge and vapor emissions, helping you meet stringent environmental regulations.

Frequently Asked Questions
-
Q1: What is the typical payback period for this MVR evaporator?
A: Depending on energy costs and operating hours, payback periods range from 1 to 3 years. Our sales engineers can provide a detailed ROI analysis based on your specific feedstock and utility prices. -
Q2: Can the evaporator handle corrosive or abrasive fluids?
A: Yes. We offer materials such as Duplex stainless steel, titanium, and Hastelloy for corrosive media. For abrasive fluids, we can incorporate wear-resistant linings or special impellers in the circulation pump. -
Q3: What is the maximum concentration achievable?
A: The final concentration depends on the product's properties. For many aqueous solutions, we can achieve up to 60-80% solids content. For high-viscosity products, forced circulation maintains good flowability. -
Q4: Do you provide on-site installation and training?
A: Yes. We offer comprehensive services including installation supervision, commissioning, and operator training. Remote support is also available via our PLC remote access feature. -
Q5: How does this compare to a falling-film evaporator?
A: The forced circulation design is more robust for liquids with scaling tendency, high viscosity, or suspended solids. Falling film evaporators are more suitable for low-viscosity, clean liquids. Our MVR forced circulation excels in demanding applications. -
Q6: What is the warranty period?
A: Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Extended warranty options can be arranged. -
Q7: Can the system be integrated with existing plant controls?
A: Yes. Our PLC system supports Modbus, Profibus, and other common communication protocols for seamless integration with DCS or SCADA systems. -
Q8: How long does delivery take?
A: Lead time varies by capacity and complexity. Typical delivery is 8-16 weeks after order confirmation. Rush orders can be accommodated depending on production schedule.
