Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a professional manufacturer specializing in MVR evaporation systems. Our factory occupies 10,000-30,000 square meters and employs 201-300 skilled workers. With years of experience in chemical processing, we present our MVR Evaporation System for Chemical Processing, designed to handle capacities from 20 to 100 m³/h with fully PLC automatic operation. This system offers exceptional energy savings and stable performance, making it the ideal solution for concentrating and crystallizing various chemical solutions.
The Mechanical Vapor Recompression (MVR) technology uses a compressor to recompress secondary steam generated during evaporation, raising its temperature and pressure before reintroducing it as heating steam. This eliminates the need for external steam supply in many cases, reducing operational costs by up to 60-80% compared to traditional multi-effect evaporators. Our system is engineered for continuous, unattended operation with precise PLC control, ensuring consistent product quality and minimal manual intervention.
Key Features & Technical Benefits
- Energy Efficiency: The MVR compressor recovers latent heat from vapor, achieving a specific power consumption as low as 20-40 kWh per ton of water evaporated. This drastically reduces steam usage and carbon footprint.
- PLC Automatic Operation: Equipped with a Siemens or Mitsubishi PLC and a user-friendly HMI touch screen, the system monitors temperature, pressure, flow rate, and compressor speed in real time. Parameters can be preset and adjusted remotely, ensuring stable operation 24/7.
- High Capacity Range: Available in standard models from 20 m³/h to 100 m³/h. Custom designs for higher or lower capacities are available upon request.
- Wide Applicability: Suitable for concentrating or crystallizing various chemical solutions, including sodium sulfate, ammonium chloride, sodium chloride, wastewater from fine chemicals, and pharmaceutical intermediates.
- Robust Construction: The main evaporator body and piping are made of stainless steel (SS304/SS316L or other corrosion-resistant alloys) to withstand harsh chemical environments. Anti-scaling and anti-fouling designs are incorporated.
- Compact Footprint: Integrated skid-mounted design saves floor space and simplifies installation. Pre-assembled and tested before shipment for quick commissioning on site.
- Low Maintenance: The compressor is the only major moving part, requiring minimal maintenance. Automatic cleaning cycles (CIP) can be added as an option.
- Compliance & Safety: Our company holds ISO9001, ISO14000, and OHSAS18001 management certifications. The system includes multiple safety interlocks (high temperature, high pressure, low liquid level alarms).

Advantages for Chemical Processing Customers
- Reduce Operating Costs: By reusing steam energy, you cut steam consumption by 90% compared to single-effect evaporators. Payback period is typically 1-2 years.
- Improve Product Quality: Precise temperature control minimizes thermal degradation of sensitive chemicals. Automated operation ensures batch-to-batch consistency.
- Increase Throughput: The continuous operation and high evaporation capacity allow for handling large volumes of chemical wastewater or process streams without bottlenecks.
- Environmental Compliance: Lower energy consumption reduces CO2 emissions. The closed-loop design minimizes vapor loss and odor release, helping meet strict environmental regulations.
- Easy Integration: The system can be easily integrated with existing production lines. Our engineers provide on-site guidance and remote support.

Frequently Asked Questions (FAQ)
Q1: What is the principle of MVR evaporation?
A: MVR (Mechanical Vapor Recompression) uses a compressor to compress the secondary steam generated from the evaporation process, raising its temperature and pressure. This high-energy steam is then returned to the heating chamber to provide heat for further evaporation, significantly reducing external steam demand.
Q2: What chemicals can this system handle?
A: The system is suitable for concentrating or crystallizing aqueous solutions containing inorganic salts (e.g., NaCl, Na2SO4, NH4Cl) and many organic compounds. For corrosive or scaling-prone chemicals, we can select appropriate materials and add anti-scaling designs. Please provide a sample or composition analysis for custom recommendation.
Q3: How much energy can be saved compared to traditional evaporators?
A: Compared to a single-effect evaporator, MVR can save 60-80% energy; compared to a triple-effect evaporator, it saves about 30-50%. Actual savings depend on the evaporation temperature and compressor efficiency.
Q4: Is the system fully automatic? Does it require 24/7 supervision?
A: Yes, the PLC system controls all key parameters, and the HMI provides alarms and data logging. Once set, the system can run unattended. We recommend routine checks but it does not require constant monitoring.
Q5: What is the footprint of a 50 m³/h system?
A: A typical 50 m³/h MVR evaporator occupies approximately 15 m × 8 m × 6 m (L×W×H) on a skid, but the exact size depends on the configuration. We can provide a layout drawing during the proposal stage.
Q6: How long does it take to install and commission?
A: Installation usually takes 1-2 weeks, and commissioning another 1-2 weeks, depending on site conditions. Our engineers will supervise the entire process.
Q7: What certifications does your company hold?
A: Our company is certified with ISO9001 (quality management), ISO14000 (environmental management), and OHSAS18001 (occupational health and safety). Specific product certifications can be arranged if required by your local regulations.
Q8: Can you provide after-sales service and spare parts?
A: Yes, we offer a one-year warranty (extendable), remote technical support, and a stock of commonly used spare parts. We also have service partners in several countries.
