130 centrifugal fans for efficient air circulation & cooling in kilns

A joint aim: high qual­ity & con­serv­ing re­sources in alu­minium pro­duc­tion

In the USA, we are ob­serv­ing a sig­nif­i­cant sup­ply deficit for flat-rolled alu­minium while the de­mand for re­cy­cled alu­minium is in­creas­ing con­tin­u­ously. A re­sponse to this chal­lenge is com­ing from a com­pany that is cur­rently plan­ning to build new alu­minium plants. There is a spe­cial fo­cus on the re­cy­cling as­pect with the aim of pro­cess­ing bil­lions of used drinks cans every year. The alu­minium that is gen­er­ated is mainly in­tended for the au­to­mo­tive, pack­ag­ing and al­loy­ing in­dus­tries. By fo­cussing on re­cy­cling and qual­ity, the com­pany is tak­ing an im­por­tant step to­wards sus­tain­abil­ity and con­serv­ing re­sources in alu­minium pro­duc­tion.

A de­ci­sive fac­tor in alu­minium pro­duc­tion is ef­fi­cient air cir­cu­la­tion and cool­ing in the kilns. Around 130 ra­dial fans of var­i­ous de­signs from Scheuch COM­PO­NENTS are be­ing used for this.

The com­pany is re­ly­ing on the kilns from EBNER In­dus­trie­ofen­bau GmbH to pro­duce high qual­ity alu­minium. These kilns trans­form raw alu­minium melt into solid blocks. Ra­dial fans play a vi­tal role in the process and there­fore af­fect the qual­ity of the end prod­uct di­rectly.

Temperature check: a pre­cise tem­per­a­ture check dur­ing the cool­ing process is es­sen­tial to en­sure that the alu­minium so­lid­i­fies evenly. Un­even tem­per­a­tures may cause un­wanted ten­sion or struc­tural changes to the alu­minium and im­pair the qual­ity.

Even cooling: the air flow gen­er­ated by the ra­dial fans en­sures that the alu­minium cools evenly. Even cool­ing is im­por­tant to min­imise ther­mal ten­sion in the ma­te­r­ial and to ob­tain a ho­mo­ge­neous crys­tal struc­ture. This has a di­rect ef­fect on the alu­mini­um’s me­chan­i­cal prop­er­ties and sur­face qual­ity.

Preventing hot spots: ra­dial fans help to pre­vent hot spots by guar­an­tee­ing an even dis­tri­b­u­tion of cool­ing air. Hot spots could cause lo­cal over­heat­ing which, in turn, causes struc­tural ir­reg­u­lar­i­ties and has a neg­a­tive ef­fect on the qual­ity of the fi­nal prod­uct.

Energy efficiency: well con­trolled ra­dial fans con­tribute to en­ergy ef­fi­ciency by op­ti­mis­ing air cir­cu­la­tion and per­form­ing the cool­ing process with the min­i­mum amount of en­ergy. Ef­fi­cient cool­ing does not just en­able qual­ity stan­dards to be main­tained but also con­tributes to cost ef­fi­ciency dur­ing pro­duc­tion.

In­te­grat­ing high qual­ity ra­dial fans does not just en­sure ef­fi­cient pro­duc­tion but also en­sures that strict qual­ity stan­dards are main­tained.

Sig­nif­i­cant com­po­nents

From consultation to shipping: centrifugal fan including accessories

Die EBNER In­dus­trie­ofen­bau GmbH has been a loyal Scheuch cus­tomer since 1975 and is over­seen by Mr Ro­man Stüber, our Se­nior Sales Man­ager. De­vel­op­ment work per­formed to­gether al­ready pro­vided a solid ba­sis for suc­cess­ful pro­jects such as the cur­rent on, in which com­pre­hen­sive con­sul­ta­tion ser­vices and care­ful plan­ning were ex­tremely im­por­tant.

Par­tic­u­larly be­fore the quo­ta­tion phase that started in the mid­dle of 2019 to con­tract con­clu­sion in De­cem­ber 2022, Mr Stüber was in con­stant con­tact with EBNER ex­perts, Mr Chris­t­ian Brand­stät­ter, Pur­chas­ing Man­ager and Mr Thomas Langth­aler, Tech­ni­cal Ex­pert, in or­der to de­velop a per­fect so­lu­tion for the end cus­tomer.

The first de­liv­ery was al­ready com­pleted on-time.

All com­po­nents were pro­duced in the fac­tory in Up­per Aus­tria, where the high­est pro­duc­tion stan­dards are main­tained. Fol­low­ing care­ful qual­ity con­trol and doc­u­men­ta­tion, Scheuch COM­PO­NENTS packed the com­po­nents pro­fes­sion­ally for trans­port by sea. The boxes were then trans­ported on an HGV to the port of Bre­mer­haven. From there, they trav­elled by sea to the USA. The de­liv­ery in­cludes:

  • Around 130 centrifugal fans

  • Baffle silencers including supports

  • Pipe silencer including supports

  • Expansion joints

  • Piping components and duct components

  • Assembly material

Seagoing Packaging

“The challenges of this project lay both in its size and in the scope of the deliveries as well as in the coordination of deadlines. However, thanks to the extremely professional co-operation with those responsible at EBNER GmbH, everything went smoothly. The seaworthy packing of 60 crates was also carried out professionally and reliably by Scheuch COMPONENTS in Aurolzmünster. Meeting the delivery deadlines required precise planning and organisation, which we did with the utmost care. It was a pleasure to be able to successfully accompany this project from the quotation phase to customer acceptance. Special thanks go to EBNER for the trust they placed in us and the first-class cooperation.”
