Dehumidification shortens working time, ensure high quality and guarantees an equal result all year around.
Desiccant technology is effective in creating a year round humidity controlled environment to avoid corrosion during surface preparation. Corrosion rates accelerate exponentially with relative humidity (RH) over 50% and most coating compliance is 80%RH on a metal surface. The effect of thermal inertia usually required the surrounding air to be 20-30%RH (4-6°C, temperature difference from surface to air) less than the required surface humidity to allow for this.
Other methods of heating require full surface heating which causes very high energy costs. Refrigeration is only effective in climates which is humid all year round and it is still unable to achieve the dryness required due to the surface humidity requirement.
