Plate falling-film evaporators
GKT plate falling-film evaporators are designed for efficient concentration and separation duties in demanding industrial environments. Combining high evaporation capacity with effective vapor-liquid separation, they are particularly well suited for fouling media and challenging process conditions.
Plate Falling-film Evaporators
How it works
The medium to be thickened is concentrated along the plate-type heating elements (lamellas), which are arranged as a bundle in the evaporator. The more volatile component is evaporated and removed from the apparatus. Optimized distribution systems are used to ensure the best possible distribution of the medium on the heating bundle and thus a high evaporation rate.
Advantages
- Ideal for heavily fouling media
- Highest evaporation rates
- Excellent separation of liquid and vapor phase
- Optimized spot-welded and laser-welded lamellas
- Long service life
- Minimal risk of fouling and corrosion
- Energy-optimized design
- Integrated droplet separator
- Condensate separation thanks to secondary heating surface
Applications
- Concentration of black liquor, spent sulfite liquor, and waste water
- Recovery and separation of solvents and alcohols
- Volume reduction of liquid-liquid mixtures
- Separation of multi-component mixtures
- Water separation
- Concentration of the liquid phase of fermentation residues in biogas plants
In-house manufacturing
All key components are manufactured at our state-of-the-art production facility in Gloggnitz, Austria, and undergo rigorous quality control throughout the manufacturing process.
A core element of our plate falling-film evaporators is the in-house production of lamellas. Using an advanced forming technology refined over decades, GKT manufactures lamellas in a wide range of geometries, materials, and welding configurations. This enables precise adaptation to process requirements, ensuring efficient heat transfer, reliable performance, and long-term operational stability.
