Cooling and cool drying in the industry
After drying, coated workpieces must remain stable in order to be processed safely. Cooling in industrial coating lines prevents deformation and surface marks. Cool drying complements this step by specifically regulating the residual moisture - essential for water-based systems.
This results in high-quality, reliable surfaces that meet the requirements of modern production lines.
VEN DRY COOL cooling tunnels and cooling channels
Stabilisation of your workpieces
VEN DRY COOL cooling tunnels and cooling channels stabilise workpieces after IR, UV or coating drying. The modules guide components through defined temperature and climate zones with uniform air flow. Sensitive surfaces remain protected and integration into new or existing lines is space-saving and flexible. The technology supports smooth transitions to material handling, industrial robotics, buffers and packaging.

Cooling in industrial coating lines: The modes of action
Cooling in industrial coating lines reduces the temperature of the coating film in a controlled manner and protects the surface from pressure sensitivity. Defined air and temperature control stabilises the coating films and increases the dimensional stability of the component. The processes creates reproducible conditions for downstream process steps.
Temperature reduction
The components lose excess heat in a controlled manner.
Surface rest
The coating becomes pressure-resistant.
Air duct
Homogeneous flow stabilises the process.
Material protection
Sensitive geometries retain their shape.
Further processing
Cooled parts can be moved and stacked safely.
Cool drying: How it works
Cool drying combines temperature and moisture reduction to safely stabilise water-based coatings. It prevents typical surface defects such as sticking, matt spots or uneven drying. The process ensures a homogeneous coating result that can be further processed - especially for sensitive functional coatings.
Residual moisture control
Remaining moisture is extracted in a defined manner.
Climate control
Temperature and air volume remain constant.
Film character
The surface dries out evenly.
Material compatibility
Even complex geometries dry reliably.
Handling safety
Components are grip and pack resistant.
Advantages of cooling in industrial coating lines and cool drying
A precisely controlled cooling and climate zone increases the quality of the entire coating line. It stabilises different materials, reduces reject rates and enables reproducible series processes. In addition, both processes can be seamlessly integrated into complete Venjakob coating and drying lines.
- High dimensional and shape stability
- Safe material handling and packaging
- Uniform surfaces with water-based coatings
- Energy-efficient climate zones
- Reliable process parameters for different geometries
- Fewer rejects and stable quality
- Smooth integration into complete Venjakob systems
Combination options with cooling in industrial coating lines and cool drying
Cooling and refrigerated drying zones adapt flexibly to different production processes. They form stable transitions between drying, material handling, industrial robotics and packaging and enable constant quality even at fluctuating speeds.
- after IR, UV or coating drying
- as a transition to material handling or industrial robotics
- for variable speeds
- controlled via the VEN CONTROL process monitoring system
- can be integrated into energy-optimised coating lines
