Drying Chamber Air Curtain Enhances Production within Legrand Galvanising Hall
- Component Distortion Minimised & Drying Efficiency Vastly imroved
- Drying Time Significantly Reduced
- Site Operation & Production Enhanced
ROFLOW have installed a successful air curtain system to the main pre-drying chamber at Legrand UK. The design, manufacture and installation of the air curtain system for mild steel components is in operation within the pre-galvanisation production stage. Legrand are a global company specialising in the electrical and digital infrastructures of buildings and produce their swifts cable management and associated products system from its manufacturing site in Scarborough, England.
Extensively, the completed mild steel components are supplied in galvanised finish. This activity is carried out in the pre-treatment and galvanisation hall. Upon completion of the pre treatment stage, the semi-wet components are suspended in the drying chamber. Heat to the drying chamber is solely provided from the galvanisation bath burner outlet.
The air curtain delivery and return air design help encapsulate the available heat inside the drying chamber, thus improving the drying efficiency. This not only improves the drying cycle time from the heat source but affects a uniform air temperature profile and minimises component distortion. Once dry, the components are then lowered into the molten zinc bath to undertake the galvanising process.
