IMPROVED MANUFACTURING EFFICIENCYCorrect humidification within an automotive manufacturing or testing facilitywill improve production efficiencies in several areas across the plant.

Paint spray boothsThe optimum humidity for the transferof paint from the spray nozzle tobodywork is 72% relative humidity.Correct humidification prevents theevaporation of water-based paint,allowing it to reach the bodywork asthe manufacturer intended. Combatingpaint evaporation also reduces theintroduction of paint dust to the spraybooth. These benefits combine toimprove the finish quality of thebodywork, reduce sandingrequirements and lower paint costs byavoiding atmospheric losses.

Paint spray booths are typically servedby central air handling units thatemploy in-duct humidifiers. Due to thehigh volume of air required low energysystems are used such as spray,evaporative or gas-fired steam.

Sanding decksBy maintaining 55% relative humidityin sanding decks, dust is suppressedand static build-up reduced. Thisprevents airborne paint dust frombeing attracted to the surface of thebodywork, greatly decreasing sandingtime and improving the quality of the finish.

As these areas are usually very warm,the air supplied to them from centralair handling units is cold with lowmoisture content. Direct airhumidification is therefore requiredand is typically provided by spraysystems as they offer humidity controlas well as around 4°C of evaporativecooling.

Engine testingExhaust emission testing must becarried out within certain temperatureand humidity ranges so it is importanthumidification systems can meet thecontrol tolerance and provide reliablehumidification.

Electric steam humidifiers are oftenused to provide close humidity controlwhile gas-fired steam, evaporative orin-duct spray systems can offer a lowercost and lower maintenancealternative.
