Natural circulation evaporator for high temperature products
Maximize evaporation efficiency with minimal fluid retention, especially suited for high-temperature, high-fouling, or non-Newtonian substances.

Concentrates Liquids and Slurries Efficiently
The Natural Circulation Evaporator system is meticulously designed for industries such as food, beverage, chemicals, and pharmaceuticals, providing robust solutions for liquid and slurry concentration. Utilizing a vertical shell-and-tube heat exchanger with a thermosiphon or rising film principle, this system ensures efficient evaporation by maintaining stable and uniform circulation. With its ability to handle high temperatures, fouling, and non-Newtonian products, it excels in processes requiring large evaporation ratios. Capable of continuous, high-capacity operations, it integrates seamlessly into existing production lines. Often constructed with corrosion-resistant materials, it supports durable use in harsh industrial environments. With options for divided boiling chambers, it reduces heating surface requirements, enhancing energy efficiency during the process. Available with automation features such as PLC control and remote monitoring, it supports modern production demands with ease. Secure this versatile solution to optimize your liquid processing needs, with customization options available upon request.
