Convection drying
A convection dryer is an industrial device designed for quick and uniform drying of the surfaces of metal elements after applying water, varnish, paint or other protective coating. These dryers use convection, which means that warm air circulates around the workpieces, which accelerates the evaporation of water, solvents or allows the polymerization of deposited dust on the workpieces.

Key features of the convection dryer
Heat source
Usually these are heating elements (electric heaters, gas burners, heat exchangers) that heat the air in the dryer. The temperature is precisely controlled according to the requirements of the drying process. Ventilation system
A powerful ventilation system ensures that warm air is evenly distributed throughout the dryer space, ensuring that all parts of the metal elements are evenly dried. Airflow
The air in the dryer circulates in the intended direction (horizontally or vertically), which allows optimal drying depending on the shape and size of the metal elements.
Control system
Advanced control systems enable automated adjustment of temperature, air flow and drying time according to the specific needs of different metal elements and types of paint. Conveyor system
Products are usually placed on a conveyor belt, which slowly moves them through the dryer. The conveyor belt and sensor elements are made of materials that are resistant to high temperatures and allow precise speed regulation. Depending on the type of workpieces and the process, tact and continuous transport through the dryer are distinguished. Insulation
The entire structure of the dryer is well insulated to minimize heat loss and increase energy efficiency.
Dehumidifiers The moisture removal system from the inside of the dryer prevents condensation and improves the quality of drying.
We distinguish the following types of convection dryers
