Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. – a trusted manufacturer with over 9 years of expertise in industrial evaporation systems. Our Triple-effect counter-current evaporator is designed to deliver high efficiency, energy savings, and reliable performance for liquid concentration and solvent recovery. With a factory size of 10,000–30,000 square meters and an annual export value of US$10–50 million, we serve clients across North America, Europe, Asia, and beyond. This evaporator comes with a 1-year warranty, free technical training, and installation support, ensuring you get maximum value from your investment.
Our triple-effect counter-current design utilizes the heat from vapor generated in each effect to preheat and evaporate the feed in the next effect, significantly reducing steam consumption compared to single-effect systems. The counter-current flow arrangement (feed enters the last effect and moves toward the first) allows for higher concentration ratios and better heat transfer efficiency. Ideal for industries such as food processing, pharmaceuticals, chemicals, and wastewater treatment, this evaporator can handle a wide range of liquids including heat-sensitive products.
Key Features & Technical Specifications
- Triple-effect thermal design: Achieves up to 60% energy savings compared to single-effect evaporators.
- Counter-current flow: Maximizes concentration gradient, allowing higher final concentration without product degradation.
- High-quality stainless steel construction: 304 or 316L grade, resistant to corrosion and easy to clean.
- PLC automatic control: Touch screen interface for real-time monitoring of temperature, pressure, flow rate, and concentration.
- Flexible heat source: Compatible with steam, thermal oil, or electric heating – customizable to your utility.
- Optional accessories: CIP cleaning system, vapor compression, vacuum pump, and condensate recovery unit.
- Compact footprint: Modular design saves floor space while maintaining high throughput.
- Easy maintenance: Quick-opening sight glasses, removable tube bundles, and accessible inspection ports.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between triple-effect counter-current and co-current evaporators?
A: In counter-current design, the feed enters the last effect and moves toward the first, while steam flows in the opposite direction. This creates a higher concentration gradient, allowing you to achieve higher final concentration with less energy. Co-current evaporators have feed and steam flowing in the same direction, which is simpler but less efficient for high-concentration applications. -
Q: Can this evaporator handle heat-sensitive liquids?
A: Yes, the triple-effect system operates under vacuum, lowering boiling points and reducing thermal degradation. The counter-current flow also minimizes the time the product spends at high temperature, making it suitable for heat-sensitive materials like fruit juices, dairy, and pharmaceuticals. -
Q: What is the typical lead time for delivery?
A: Lead time depends on the capacity and customization. For standard models, it is usually 30–45 days. Customized units may take 45–60 days. We can provide an exact timeline after receiving your specifications. -
Q: Do you provide installation and commissioning support?
A: Yes, we offer free technical training and installation support. Our engineers can guide your team remotely or travel to your site (travel expenses at client’s cost). We also provide detailed manuals and drawings. -
Q: What certifications does your evaporator have?
A: Our manufacturing facility is certified with ISO9001, HACCP, SA8000, OHSAS18001, and many other standards. Individual products can be certified according to your requirements (e.g., CE, ASME) – please inquire for details. -
Q: How do you ensure the quality of the evaporator?
A: We follow strict quality control procedures from raw material inspection to final performance testing. Each unit is tested for leak tightness, vacuum holding, and heat transfer efficiency before packaging. We also offer a 1-year warranty. -
Q: What is the minimum order quantity?
A: Our minimum order quantity is 1 unit. However, for small-capacity laboratory models, we have standard designs available. Contact us for details. -
Q: Can I customize the evaporator for my specific liquid?
A: Absolutely. We can adjust the number of effects, materials, heat source, control system, and additional features like anti-foaming devices or CIP systems. Just provide your liquid properties (viscosity, boiling point, solids content, etc.) and we will design a suitable solution.
