Stadco chooses Todd Engineering to supply paint booth

When Stadco Cooling reviewed their requirement for an in-house paint application to meet EPA regulations they had no hesitation in awarding the contract to Todd Engineering (Finishing Systems) Co Ltd (TEFS) for their Shrewsbury site.

The combined Spray and Cure facility has been designed to meet Stadco's requirement of a dedicated booth for the preparation of skid mounted water cooling systems and the application of wet paint. This now provides the correct environment for application and containment of overspray that painting operations cause.

In order to meet the criteria the booth is ventilated with a rate of air movement known to be capable of capturing waste materials and removing it from the working area. Air movement being downwards, this not only removes debris material from the operators working zone, but also draws any potential containment in the form of dried paint etc away from the processed parts.

Supply air has been taken from outside of the building, being heated by a gas fired burner prior to entering the booth via roof mounted high efficiency filters within a plenum header. The supply air temperature varies according to the booth mode of operation. This air input is utilised within each of the booth's modes be it spraying, flash off or final cure. The temperature is variable up to 80°C and the time at the elevated temperature is pre-determined via a controlling timer.

Exhaust air is constantly drawn from the booth through a rear mounted exhaust plenum. The air being cleaned by a high efficient filter media prior to discharge to atmosphere via the exhaust fan and stack during spray mode and re-circulated during flash and cure mode. All filter medias used within the booth facility are low cost consumables being easily maintainable from inside the booth.

The high specification of the facility has given Stadco Cooling the capability of producing painted assemblies to a standard of finish normally associated with the automotive industry, as well as the knowledge of a reliable and robust built installation that complies with required Government legislation.

Dave Watson, Stadco Cooling says 'As dedicated designers and manufacturers of Paint Finishing Systems, TEFS where immediately able to provide a cost effective solution. We needed a booth to be specifically designed to meet our need of a facility located within an existing area of the factory in order to compliment the flow of goods from the manufacturing workshop. TEFS achieved this without any problem.'
