Need a new dust extraction system but can’t afford to stop production? This world’s most energy efficient, safest dust extraction system was installed in a weekend. An international company, with a large presence in New Zealand has as part of its operation, a number of recycling/retread plants around the country. One of these plants at Christchurch has become a much busier place, as the city rebuild has increased demand for used worn out tyres to be moved through the factory and re-cycled as ‘good as new’ hours later. This is not only good for the 36 April 2016 planet but good for local company’s costs. However, this increased production brings its problems: re-cycling tyres involves scouring the old tyre to give a good adhesion base for the new ‘tread’ which is chemically and heat glued to the old tyre. The scouring produces large amounts of dust and oil which need to be prevented from contaminating not only the work area and its staff, but also the outside environment. At the Christchurch plant the existing system was failing to cope with the increased demand leading to poor suction and escaping rubber dust. The need for a new improved system was obvious but the company had three additional priorities: The new system must be install and working without delaying production It must be as energy efficient, cheap to run and environmentally responsible as possible It must be a proven design, and with greater emphasis now in NZ of corporate responsibility, safety for staff and surrounding companies was paramount. Fortunately the company had previous experience replacing dated extraction systems at other plants in Rotorua and Auckland with state of the art Danish made systems from local company NZ Duct+Flex. NZ Duct+Flex promised to start dismantling the old units at lunch time Friday, and have the new system installed by Sunday, ready for the electrical connection and commissioning.
