A weld­ing so­lu­tion to suit the way you move

DEMM Engineering & Manufacturing - - WELDING -

Fam­ily- owned Mel­rose Kiwi Con­cept Chairs is all about mov­ing. For over 25 years, they have sup­plied mo­bil­ity prod­ucts, and in par­tic­u­lar are a ma­jor brand for wheel­chairs – now the largest man­u­fac­turer of chairs in NZ and Aus­tralia. Pro­vid­ing cus­tomised wheel­chairs for both chil­dren and adults, their Christchurch based man­u­fac­tur­ing plant re­quires ex­ten­sive knowl­edge of phys­i­cal and cog­ni­tive dis­abil­i­ties, prod­uct ca­pa­bil­i­ties and main­te­nance, in­surance, health fun­ders and re­ha­bil­i­ta­tion re­quire­ments. With six full time welders and other staff in­volved in the huge num­ber of chairs man­u­fac­tured each week, they also need ef­fec­tive fume ex­trac­tion.

As the com­pany has grown, Mel­rose de­cided to cen­tralise their ex­trac­tion sys­tem but wanted the flex­i­bil­ity for each ex­trac­tion point to cover two bays. Matt Darn­brough, South­ern Ter­ri­tory Man­ager for NZ Duct+Flex vis­ited the site to see how best to achieve ef­fec­tive fume ex­trac­tion with the work­shop’s ac­tiv­ity.

NZ Duct+Flex’s own in­stal­la­tion team have in­stalled hun­dreds of the blue and yel­low Euro­pean sourced fume arms for weld­ing fumes, and here six 4m reach 160mm arms were used, as well as a mo­bile FumeCube to give Mel­rose all the flex­i­bil­ity needed as spe­cial­ist work is car­ried out in dif­fer­ent parts of the work­shop.

“Our sup­pli­ers have been around for decades and their prod­ucts have been tried and tested and en­hanced over this time. No other com­pany can of­fer what we of­fer in NZ, a source of LIPLOCK mod­u­lar duct­ing com­po­nents, fans, fil­tra­tion units, all man­u­fac­tured by the same Dan­ish com­pany (JKF In­dus­tri), guar­an­teed to work as a sys­tem ef­fi­ciently and ef­fec­tively, “says Sales Man­ager Ge­off Eb­don. ”All our fume so­lu­tions are also sourced from an­other ma­jor Euro­pean sup­plier.”

An­nette Mel­rose con­firmed that all is run­ning re­ally well, do­ing what it ’s sup­posed to do: im­proved air qual­ity for staff.

With their own in­stall team, NZ Duct+Flex are fit ting these prod­ucts ev­ery day. For static fume so­lu­tions, the fume arm range is very ro­bust with metal tube arms and hoods, ex­ter­nal hing­ing mean­ing the de­bris be­ing ex­hausted can­not cause the hing­ing to wear or be­come jammed, ie LOW main­te­nance. The com­pany carry all fume arms in stock avail­able for im­me­di­ate de­liv­ery from 75mm dia with a one me­tre reach up, to 160mm dia with a 4m reach. Fume Arms can be driven by the fume arm fan range or as in this case, for larger work­shops with a cen­tralised sys­tem a JKF fan can be used. For Mo­bile so­lu­tions there is a choice of a one- arm or two- arm fume cube unit – a solid but com­pact mo­bile unit with pre- mesh fil­ter for sparks, pull out car­tridge fil­ter and fan all in one unit.
