Qingdao Conqinphi Environmental Technology Group Co., Ltd., established in 2015, is a professional manufacturer with a 10,000–30,000 square meter factory and 201–300 experienced employees. We hold multiple certifications including ISO9001, ISO14000, OHSAS18001, HACCP, SA8000, and more, ensuring that every product meets rigorous quality and safety standards. Our Forced Circulation MVR Evaporator with Incoloy 825 Heat Exchanger represents the latest advancement in industrial evaporation, designed specifically for highly corrosive liquid environments. With an annual export value exceeding US$10–50 million and serving markets across North America, South America, Europe, Asia, Africa, and Oceania, we bring global expertise to your wastewater treatment and concentration needs.
This evaporator utilizes Mechanical Vapor Recompression (MVR) technology, which significantly reduces energy consumption by recycling latent heat from vapor. The heart of the system is a Incoloy 825 heat exchanger, a nickel-iron-chromium alloy with molybdenum, copper, and titanium additions, providing exceptional resistance to chloride stress corrosion cracking, pitting, and general corrosion. It is ideal for handling brines, hydrochloric acid, sulfuric acid, phosphoric acid, and other aggressive chemicals. The forced circulation design ensures a high heat transfer coefficient, preventing scaling and fouling even when treating high-viscosity or high-concentration liquids. The system is fully compatible with both 50Hz and 60Hz power supplies, making it suitable for global installation.
Key Features and Technical Advantages:
- Energy-Efficient MVR Process: Compresses vapor to increase temperature and pressure, then uses that energy to heat the feed liquid. Energy consumption is typically 70–90% lower than traditional multi-effect evaporators.
- Superior Corrosion Resistance: Incoloy 825 withstands a wide range of corrosive media, including chlorides, sulfides, and acidic environments. Suitable for pH values from 1 to 14 in many applications.
- Forced Circulation Design: Prevents scale deposition and fouling, ensuring stable long-term operation. Ideal for liquids with high suspended solids, high viscosity, or tendency to crystallize.
- Flexible Power Compatibility: Designed for 50Hz and 60Hz electrical systems; voltage can be customized (380V, 440V, 660V, etc.) according to local standards.
- Compact Modular Construction: Pre-assembled skid-mounted units reduce on-site installation time and cost. Control system with PLC and HMI allows precise monitoring and automation.
- Wide Range of Applications: Suitable for industrial wastewater (chemical, pharmaceutical, textile, mining), brine concentration, zero liquid discharge (ZLD) systems, and product concentration in food & beverage industries.

Frequently Asked Questions (FAQ)
-
Q: What is an MVR evaporator and how does it save energy?
A: MVR stands for Mechanical Vapor Recompression. It compresses the vapor produced during evaporation, raising its temperature and pressure, then uses that hot vapor to heat the incoming feed. This recycles the latent heat, reducing energy consumption by up to 80–90% compared to conventional evaporators. -
Q: Why is Incoloy 825 used for the heat exchanger?
A: Incoloy 825 is a nickel-based superalloy with excellent resistance to chloride stress corrosion cracking, pitting, and general corrosion in acidic and alkaline environments. It is ideal for treating brines, hydrochloric acid, sulfuric acid, and other aggressive chemicals that would corrode stainless steel. -
Q: Can the evaporator handle high-viscosity or scaling liquids?
A: Yes, the forced circulation design maintains a high flow velocity across the heat exchanger surface, which prevents scale deposition and handles liquids with moderate to high viscosity. It is suitable for solutions with high suspended solids or that tend to crystallize. -
Q: Is the equipment available for both 50Hz and 60Hz power systems?
A: Absolutely. Our evaporator is designed to operate on either 50Hz or 60Hz power supplies. We also customize the voltage (e.g., 380V, 440V, 660V) to match your local electrical standards. Please specify your requirement when ordering. -
Q: What is the typical lead time and delivery terms?
A: Lead time depends on capacity and customization; standard units are 4–8 weeks. We ship from Qingdao port, with FOB, CIF, or DAP terms available. We coordinate logistics and provide all necessary documentation. -
Q: Do you provide after-sales support and commissioning?
A: Yes, we offer remote technical support, on-site commissioning assistance (optional), and spare parts supply. Our engineers can travel to your site for training and troubleshooting. Warranty is typically 12 months from installation. -
Q: Can the evaporator be integrated into an existing ZLD system?
A: Yes, our Forced Circulation MVR Evaporator is commonly used as a key component in zero liquid discharge (ZLD) systems. It can be combined with pre-treatment, crystallizers, and drying units. We can design a complete solution for your plant. -
Q: What certifications does your company have?
A: We are certified for ISO9001, ISO14000, OHSAS18001, HACCP, SA8000, and several other standards. We also follow ASME or PED guidelines upon request. All equipment is tested and certified before delivery.
