Cooling of the products or items before application is essential in order to be able to control the thickness of the layer.
Too high a temperature when painting, will create problems in controlling the layer thickness. Also the final quality of the paint can be affected, visually as well as functionally.
Furthermore the internal environment of a cooling zone is a benefit. During winter it might be nice to get free heat from the products, but in the summer you want the heat taken out of the room.
Our cooling zone therefore very often comes in a version enabling you to decide either to return the circulated air to the room, or to let it out of the building in the summer.

Application and use
Cooling zones are used for lines in which the conveyor conveys the products continuously or stop-go.
The most usual applications are:
- After drying oven, before application
- After curing, before unloading
It is a circulation cooling zone. It means that air is circulated around the product or item at a high speed, giving a very effective cooling process. Other fans will ensure a certain exchange of air in the cooling zones. This airflow is made as a reverse flow system.
The zones can be with doors, but most often with a plain opening.
The cooling zone is constructed from insulated sections and covered with powder coated cassettes or optional galvanized cassettes.
