Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our latest Multi-Effect Vacuum Evaporator with Titanium Tubes for Seawater Desalination. As a leading manufacturer with over 8 years of experience, we have supplied efficient desalination solutions to clients across North America, Europe, Southeast Asia, and Africa. This evaporator combines advanced multi-effect vacuum technology with corrosion-resistant titanium tubes to deliver high-purity freshwater while minimizing energy consumption. Whether you need to treat seawater for drinking, industrial processes, or irrigation, our system offers robust performance and long service life.
Key Features & Benefits
- High Efficiency Multi-Effect Design: Each effect recovers latent heat, reducing energy usage by up to 60% compared to single-effect evaporators. Up to 6 effects are available, achieving a GOR (Gained Output Ratio) of 5-8.
- Corrosion-Resistant Titanium Tubes: Titanium offers exceptional resistance to chloride corrosion in seawater, extending tube life to over 20 years. Zero pitting or stress corrosion cracking under normal operation.
- Low Operating Temperature: Operates at 50-70°C under vacuum, reducing scaling and allowing use of low-grade heat sources such as waste heat or solar thermal.
- PLC Automatic Control: Touch-screen interface with real-time monitoring of pressure, temperature, and flow. One-button start/stop, with remote monitoring option.
- Modular & Compact Footprint: Skid-mounted design for easy installation. Capacity ranges from 10 to 500 tons per day, customizable per site requirements.
- Minimal Chemical Usage: No need for anti-scalants in most seawater applications, thanks to low temperature and vacuum operation. Reduced environmental impact.

Frequently Asked Questions
-
Q: What is the typical lifespan of the titanium tubes?
A: Under normal operating conditions (low temperature, pH neutral), titanium tubes can last over 20 years with minimal degradation. They are highly resistant to seawater corrosion. -
Q: Can this evaporator handle brine with salinity higher than seawater?
A: Yes, it can treat brine up to 100,000 ppm with optional modifications. However, for extremely high salinities, a scale prevention system may be recommended. -
Q: What is the energy consumption per cubic meter of freshwater produced?
A: For a 6-effect unit without MVR, thermal energy equivalent to about 15-25 kWh/m³ (depending on steam source) and electrical energy of 0.5-1.5 kWh/m³. With MVR, electrical consumption is around 8-15 kWh/m³. -
Q: Do you provide installation and commissioning services?
A: Yes, our engineers can supervise installation and provide on-site commissioning. Remote support is also available. -
Q: What is the delivery time for a standard 100 m³/day unit?
A: Typically 45-60 days after order confirmation, depending on configuration and current production schedule. -
Q: Does the system require anti-scalant chemicals?
A: In most seawater desalination applications, no anti-scalants are needed due to the low operating temperature and vacuum conditions. For certain high-hardness waters, a minimal dosage can be used. -
Q: Can I integrate waste heat from my plant to run this evaporator?
A: Absolutely. The low-temperature operation (50-70°C) makes it ideal for utilizing waste heat from diesel generators, industrial processes, or solar collectors. -
Q: What certifications do your products hold?
A: We have ISO9001, ISO14000, OHSAS18001, and other certifications available. Specific certifications can be provided upon request.
