Humidification and humidity control for the automotive industry.


Every sector of the automotive industry needs precise control of relative humidity to protect product quality and meet existing productivity and safety standards. Proper humidification in automotive factories will improve production efficiency in all processing areas, including sanding decks, spray booths, seat cover production and engine testing cells.


Engine testing – Exhaust emissions testing must be performed at certain temperature and humidity levels, maintaining a correct level of humidity is essential. Electric steam humidifiers are often used to ensure proper humidity control, however, direct humidification or in duct humidification systems offer lower cost operation.


Sanding decks – By maintaining 55% relative humidity in sanding decks, dust is suppressed and static build-up reduced. This prevents airborne paint dust from being attracted to the surface of the bodywork, greatly decreasing sanding time and improving the quality of the finish. Because there are high temperatures in the sanding area, air treatment systems are used to introduce cold and dry air leading to a decrease in relative humidity to the extreme. Therefore, direct humidification of the air is required and is usually provided by spray humidification systems as they provide humidity control as well as approximately 4 ° C of evaporative cooling.


Paint spray booths – The optimum humidity for the transfer of paint from the spray nozzle to bodywork is 72%RH. At this level evaporation of the paint is reduced allowing it to reach the bodywork as the manufacturer intended. Reducing moisture evaporation from the paint also reduces the amount of paint dust that is introduced to the spray booth. Paint booths are usually serviced by air handling units that use in duct humidifiers. Due to the large volume of air required, the use of energy-efficient systems, such as spray humidification systems, vaporization or gas-fired steam humidification systems, is suggested.
