Drying technologies

From classic technology equipment through to radiation curing systems

The bandwidth of drying procedures ranges from the classic (physical/chemical) drying technology through to radiation curing systems. The corresponding drying types need to be applied depending on the painting process. Remmers supplies highly-efficient paint technologies for the overall application spectrum.

MOS drying

In the MOS drying process, radiation of a wavelength of 2.54 GHZ energy is applied to the layer structure which excites the water molecules selectively/specifically. This means that the water molecules can leave the coating film and be transported away via a float or jet dryer.

UV drying

Ultraviolet drying requires special UV-curing coating materials with photo-initiators; after the physical drying of watery products using the above-mentioned system equipment, the surface is radiated with UV beams that causes a chemical reaction - cross-linking process. Classic lamps for hardening are gallium and mercury lamps.

LEC/LED drying

Low-Energy-Curing/Light-Emitting diode drying involves UV hardening with a lower energy input. UV materials cure at a lower spot output and the energy costs can be reduced significantly.

ESH drying

ESH drying is a special type of radiation curing drying and hardening (under electrostatic).

Drying tunnel

For instance, the circulating air dryer is suitable for trolleys with continuous air exchange and a rising temperature of approx. 25 °C - 30 °C in the initial range, 40 °C - 45 °C in the middle range and a cooling range of approx. 25 °C - 20 °C. The respective clocking and idle times of the coated profile woods in the drying tunnel depend particularly on the applied wet layer thicknesses.

IR drying

IR drying involves radiating the freshly coated surface with medium-wave infrared emitters; the radiation absorbs the water in the coating materials, converts this into heat and evaporates it. A combination of infrared radiation and circulating air drying would be beneficial so that effective drying of the respective coating material can be guaranteed.

OIR drying

This drying procedure uses infrared emitters whose emission spectrum is specifically set to the absorption curve of the volatile paint constituents that need to be removed (targeted heat input into the paint coat). A decisive benefit of this drying technology is that the lacquer dries evenly, quickly and gently from inside out. After radiation, the volatile lacquer components are removed by the float or jet dryer.
