Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a leading manufacturer specializing in advanced environmental solutions. With a factory spanning 10,000–30,000 square meters and a dedicated team of 201–300 employees, we bring years of expertise in producing high-efficiency evaporation systems. Our Automatic MVR Evaporator with Heat Pump for Seawater Desalination (316L stainless steel, 50Hz) represents the cutting edge of energy-saving desalination technology. Designed to convert seawater into fresh water with minimal energy consumption, this system is ideal for industrial, agricultural, and municipal applications requiring reliable, large-scale desalination.
This evaporator integrates Mechanical Vapor Recompression (MVR) technology with a high-performance heat pump, achieving exceptional thermal efficiency. The 316L stainless steel construction ensures excellent corrosion resistance against saline environments, extending equipment lifespan and reducing maintenance frequency. Fully automatic operation, controlled by a PLC touchscreen interface, minimizes manual intervention while maintaining precise process parameters. With a standard 50Hz electrical specification, the unit is compatible with many global power grids.
Key Features & Technical Specifications:
- High Energy Efficiency: MVR technology recycles vapor latent heat, reducing energy consumption by 60–80% compared to traditional thermal evaporators. The integrated heat pump further optimizes performance.
- 316L Stainless Steel Construction: Superior resistance to chloride stress corrosion, suitable for direct seawater treatment without pretreatment.
- Fully Automatic PLC Control: Touchscreen HMI allows remote monitoring, real-time data logging, and automatic adjustments for feed flow, temperature, and pressure.
- Compact Modular Design: Space-saving footprint; turnkey installation with pre-assembled components.
- Low Operating Costs: Minimal chemical usage (no pre-softening needed) and low power consumption.
- Flexible Capacity Options: Customizable evaporation rates from 1 ton/day to 100+ tons/day (contact us for specific ranges).
- Environmentally Friendly: Zero liquid discharge (ZLD) capability; reduces brine volume and environmental impact.

Frequently Asked Questions
1. Can this MVR evaporator handle high-salinity seawater directly?
Yes, the 316L stainless steel design is specifically corrosion-resistant to chloride concentrations typical of seawater (up to 45,000 ppm TDS). It does not require extensive pretreatment, though a simple filtration is recommended to remove large debris.
2. What is the typical power consumption per ton of fresh water produced?
For standard seawater, the system consumes approximately 8–15 kWh per ton of fresh water, depending on operating temperature and capacity. This is significantly lower than traditional thermal desalination methods.
3. Is the system compatible with 60Hz power grids?
While the standard model is designed for 50Hz, we can provide a 60Hz version or install frequency converters. Please specify your local grid requirements when ordering.
4. What is the expected lifespan of the evaporator?
With proper maintenance, the 316L components can last 15–20 years or more in seawater service. The heat pump and compressor typically have a 10–15 year lifespan with routine servicing.
5. How much space is required for installation?
The footprint varies by capacity. For example, a 10-ton/day unit occupies approximately 20–30 square meters. We provide detailed layout drawings and can support modular installations in limited spaces.
6. Does the system require specialized operators?
No. The fully automatic PLC control allows easy operation after basic training. Remote monitoring and alarms can be configured to alert maintenance staff.
7. Can I integrate this with existing water treatment systems (e.g., RO permeate polishing)?
Absolutely. Our MVR evaporator produces high-purity distillate (TDS <10 ppm) that can be blended with other water sources or further polished. We can design the interface per your project requirements.
8. What after-sales support do you provide?
We offer comprehensive support including installation supervision, commissioning, spare parts supply, and remote technical assistance. Our team is available 24/7 for critical issues. Service centers can be arranged for major markets.
