Frequently Asked Questions
-
What is the difference between a double four-effect and a conventional four-effect evaporator?
The double four-effect design incorporates two independent four-effect trains, allowing higher total capacity, redundancy, and flexible operation (parallel or series). This configuration also offers better energy recovery and process control. -
What materials are used for the evaporator construction?
Standard construction is 316L stainless steel. Other alloys such as 304 SS, duplex stainless steel, or Hastelloy are available depending on the corrosiveness of your feed solution. Please advise your specific chemical composition. -
How long is the delivery time?
Lead time typically ranges from 45 to 90 days, depending on the customization level and order volume. Faster delivery may be arranged for standard units. -
Do you provide installation and commissioning support?
Yes, we offer remote guidance and on-site commissioning services (optional). Our free technical support covers troubleshooting and maintenance advice. -
What is included in the mill test report?
The mill test report provides material certifications, weld inspection results, dimensional checks, and pressure test records. It is essential for quality assurance and regulatory compliance. -
Can the evaporator handle viscous or fouling liquids?
Yes, the double four-effect design can be equipped with mechanical cleaning systems (e.g., scraped surface or forced circulation) to handle high-viscosity or scaling-prone fluids. We recommend a process evaluation to determine the best configuration. -
What is the warranty coverage?
We offer a 1-year warranty covering defects in materials and workmanship. Free technical support is available during the warranty period, and extended service contracts can be arranged. -
How do you ship the evaporator?
We ship from Qingdao Port in containers or as breakbulk cargo, depending on size. All units are securely packed and protected for ocean freight.
