MetalFix ® Waterbased Primer For Heavy Rust A single-pack water-based rust converting etch primer, for application over rusted steel. The product converts the rust layer into a metal phosphate and simultaneously cures into a tough abrasion-resistant skin, which is impervious to further rusting. www.engineeringnews.co.nz 31 the heart of his research. He explains: “In the past, we’ve tapped into the higher-temperature geothermal fluids. This naturally means we’re left with the lower temperatures, and we can make use of the ORC in this instance. The other application for the ORC is with the waste heat produced by all kinds of industries across New Zealand; steel and paper plants, for example. Where it would normally be vented into the atmosphere, we could recapture it and produce power.” Matthew points out that there is zero cost to the company or industry – they’re producing it as part of their regular operations. It could be directed back into the plant, or even back into the grid and sold on. The economic benefits of an optimised ORC are significant and were the driving factor behind the commissioning of several pilot plants. Now up and running, they will be used to demonstrate the technology Brent’s team has developed. The team will advise companies on how to develop and implement it into their processes. Once they are in regular use throughout New Zealand, the new ORC designs could be applied to geothermal industry around the world – or indeed any MetalFix® industry that produces waste heat as * Water wash up (no solvents) a potential resource.

Brent says: “Our research and work on this technology can help industries producing waste heat to prospect those resources. We hope to KTKemTek see a thriving industry in New Zealand centred on this technology.” for details visit: www.kemtek.co.nz For details visit: www.kemtek.co.nz EN029 HM040 DUST EXTRACTION GOES PRO Prowood, New Zealand’s leading manufacturer of certified and laminated timber products has recently installed an Egmont Air dust extraction system in the Tasman district. Having experienced difficulties with poor suction and the original cyclone system discharging dust to atmosphere, Mr John Woodman from Prowood decided it was time to upgrade the system. Prowood’s expertise in laminated timber including the next generation in laminated veneer lumber (LVL) this process requires powerful suction which is critical to ensure clean machining and planning of timber. Egmont Air conducted a complete analysis of the existing extraction system and specified a large modular system with high-efficiency fan to provide high levels of suction and guaranteed cleanair discharge to atmosphere. The system is fitted with automated reverse-air cleaning and connected to Prowood’s existing container-filling system to allow efficient filtration and collection of shavings. Mr Woodman says, “The suction is brilliant and we are discharging clean air to protect the environment”. Egmont Air Systems are not only limited to wood-dust, being experienced in all types of dust or fume including smoke, fumes, paint spray, metallic dust and more, many solutions are available offthe shelf, for a free onsite evaluation for your requirements contact them today, Tel: 0800 781 200 or Visit: www.egmontair.co.nz
