Powder baking oven
After the powder has been applied, the work pieces with the adhering powder must be passed to the powder baking oven. The baking temperatures vary between 180 °C and 240 °C depending on the type of powder.The dryers are pre-assembled as much as possible allowing the finished elements or components to be delivered to the construction site completely assembled.
Residual water dryer
After the work pieces have left the pre-treatment facility, the water particles still adhering to the surface need to be dried. Special interior baffles in conjunction with the heated recirculating air allow the parts to be passed on to drying immediately following the coating process.
Depending on the lacquer system previously processed, lacquer drying is done with varying temperatures and residence times. We hereby work with recirculating air processes and high-quality dryer insulation to keep the energy costs at a minimum.In terms of energy aspects, further consideration must be given to the intake and discharge openings of the oven to keep the energy loss at a minimum by implementing appropriate measures.
Infrared and UV Drying
Infrared and UV Dryers as alternative to conventional drying processes.
As alternative to conventional recirculating air drying, drying can be achieved by
- Infrared or
- UV Radiation
Attention must be given to the paint systems employed since special UV hardening lacquers must be used for UV Drying.
With refrigerant drying, drying takes place at a temperature between 30 °C and 60 °C. The low temperature process utilizes the energy potential from the moist air. The dry air passes through a closed cycle. To achieve an extremely dry climate, the moist air is continually dehumidified in the bypass. Refrigerant drying can be applied both in Continuous flow as well as Chamber driers.
