Key Features & Technical Specifications
- Duplex Stainless Steel Construction: Offers superior resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, making it ideal for high-salinity and aggressive wastewater streams.
- 55kW High-Efficiency Compressor: Provides stable and reliable Mechanical Vapor Recompression (MVR), reducing energy consumption by up to 70% compared to traditional evaporation methods.
- Zero Liquid Discharge Capability: Recovers up to 95% of water as clean distillate, leaving concentrated solids for disposal or further reuse, helping you achieve complete compliance with discharge regulations.
- PLC Automatic Control System: Equipped with a touchscreen HMI for real-time monitoring of temperature, pressure, feed rate, and other critical parameters, enabling one-person operation and remote troubleshooting.
- Customizable Design: Processing capacity, voltage, cooling method, and pre-treatment configurations can all be tailored to your specific site conditions and wastewater characteristics.
- Robust Safety Features: Includes overpressure protection, low-level alarms, emergency shutdown, and corrosion-resistant components for long-term trouble-free operation.

Detailed Advantages & Benefits
- Energy Efficiency: MVR technology recycles the latent heat of vaporization, consuming only 30-50 kWh per ton of evaporation compared to 100-150 kWh for traditional evaporators. The 55kW compressor is perfectly matched to balance performance and power savings.
- Corrosion Resistance: Duplex stainless steel (with ~22% chromium, 3% molybdenum) withstands high chloride concentrations (up to 1500 ppm Cl⁻) and low pH environments, extending equipment life and reducing maintenance frequency.
- Environmental Compliance: Achieve zero liquid discharge without chemical pre-treatment in many cases, eliminating wastewater discharge fees and potential fines. The system produces high-quality distillate (conductivity
- Compact Footprint: Our integrated skid-mounted design minimizes onsite installation work, requiring only connection to power and piping. Optional modular expansions allow capacity upgrades without replacing the entire system.
- Low Maintenance: Self-cleaning cycles and anti-scaling measures reduce downtime. The durable compressor and stainless steel components require only routine inspections and lubrication changes every 6 months.
- Customization Options: We offer additional pre-treatment (e.g., DAF, UF), post-treatment (e.g., RO polishing), and automation upgrades tailored to your specific wastewater profile (e.g., high TDS, organic content, or variable flow rates).

Frequently Asked Questions
Q1: What is the typical evaporation capacity range for this MVR evaporator?
A: The base model with a 55kW compressor can handle approximately 10 to 50 tons per day of water evaporation, depending on feed temperature and solids concentration. We can customize the system for higher or lower capacities upon request.
Q2: Can this evaporator handle wastewater with high chloride content (e.g., seawater RO brine)?
A: Yes. The duplex stainless steel construction is specifically chosen for its excellent resistance to chloride-induced stress corrosion cracking (SCC). It can safely handle chloride concentrations up to 1500 ppm at typical operating temperatures. For extreme conditions, we offer super duplex or other alloys.
Q3: What are the electrical requirements and power consumption?
A: Standard voltage is 380V / 50Hz / 3-phase. Total connected load (including feed pump, condenser fan, control system) is approximately 65-75 kW. We can adapt to 440V/60Hz or other voltages with transformer adjustments. The specific energy consumption is around 30-35 kWh per ton of evaporated water under nominal conditions.
Q4: Do you provide installation and commissioning services?
A: Yes. We offer onsite supervision for installation and commissioning by our experienced engineers. Remote assistance via video call is also available. A detailed installation manual and technical documentation are provided with every system.
Q5: What is the warranty period and after-sales support?
A: Standard warranty is 12 months from the date of commissioning. We supply critical spare parts (compressor, valves, sensors) and provide prompt technical support via email, phone, or video conference. Extended warranty and maintenance contracts are available.
Q6: How long does it take to manufacture and deliver?
A: Typical lead time is 30-45 working days after receipt of down payment and final technical approval. Customized designs may require additional 10-15 days. Shipment is via sea from Qingdao port; transit time depends on destination.
Q7: Can your MVR evaporator treat wastewater with organic contaminants (e.g., from food or chemical industries)?
A: Yes, but the system design may need to incorporate anti-fouling measures and possibly pre-treatment (e.g., DAF or biological) to protect the evaporator surface. We will analyze a sample of your wastewater to recommend the optimal configuration.
Q8: Do you have certifications like ISO or CE?
A: Our manufacturing facility is certified under ISO9001, ISO14001, and OHSAS18001. We also hold other certifications (HACCP, TL900, SA8000, etc.) that can be provided upon request. For specific markets like the EU, we can arrange CE marking compliance as an optional service.
