extraction arms located close to die cavities. Capture hoods need to be located as close as practical to extract the airborne contaminants at or near the generation source to protect the machine operator and to prevent fume migration. l Ambient air collection When used in conjunction with source capture, ambient air collection can help remove the ambient haze caused by airborne pollutants. It should be used in conjunction with source capture. Foundry emission control systems are increasingly advanced. Developed by UK-based Western Air Ducts (WAD), Inteliair is an intelligent air-control system that reduces operating costs, lowers carbon footprints and improves air quality by optimising the efficiency of dust extraction, fume extraction and ventilation systems. This is achieved by automatic continuous monitoring of demand, and regulation of the extraction or supply of air in accordance with that demand. It can provide a foundry with significant cost savings. “The results of the numerous systems that we have installed show that energy use by extraction systems is reduced by between 42% and 88%,” says Andrew Lintern, director of WAD. The Climatic system from Danish company Infuser uses Gas Phase Advanced Oxidation (GPAO) to remove pollution from industrial emissions. First ozone is mixed with the polluted exhaust. The mixture is then irradiated with high intensity UV light which transforms ozone into OH (hydroxyl) radical molecules. These are extremely reactive towards most VOCs, transforming them into aerosol particles. As a final treatment stage, these particles are removed using an electrostatic precipitator. The Infuser system’s main area of use is for treating the exhaust air of core-shooting machines, drying furnaces and mould production plants, due to its high concentration of amines, formaldehyde, VOCs, BTEX (benzene, toluene, ethylbenzene and xylene) and odours. Future focus For foundries, improved environmental performance makes sense for many reasons. It can mean: l Improved efficiency leading to significant cost savings l Avoidance of environmental fines and prosecutions l A better image in the community and media l A reduced environmental footprint l A happier, more motivated and better skilled workforce In addition, a growing number of foundry customers want to be sure their metal caster of choice is environmentally progressive and operating a sustainable business model. By addressing issues such as energy efficiency, waste minimisation and emissions control, metal casters can reassure them on both fronts. n FEATURE 18 www.metals.rala.com.au The high concentrations of formaldehyde, VOCs and BTEX generated through the casting process can be increasing removed with the aid of advanced environmental systems. Optimised areas of use of Climatic solutions in the production process of a typical foundry. Reliable quality metals analysis Elemental analysis is essential to the quality of your metal products.
