FEUER powertrain North America, Inc., Mississippi, USA

Large filtration systems by LTA Lufttechnik Gmbh

In 2016, Feuer put a variety of filtration systems into operation at their Mississippi site, including wet and dry filtration systems based on the electrostatic and mechanical separation principle.

A clever filtration concept for the crankshaft plant

In 2016, Feuer put a variety of filtration systems into operation at their Mississippi site, including wet and dry filtration systems based on the electrostatic and mechanical separation principle. In total, four LTA filtration systems with a total extraction capacity of 104,000 m³/h were designed for extracting aerosols and established on site. Four pipelines totaling 600 meters were laid. The aim was to implement redundant wet filtration systems along with systems with an automatic cleaning function to remove the oils, emulsions and dust output by the machines. To do so, all the systems (1x dry, 2x oil and 1x emulsion) were equipped with a separate switch cabinet and the exhaust air emissions were permanently monitored. Each machine connection was also fitted with a duct separator, a volume flow flap and flexible polyurethane hoses.

FEUER powertrain North America, Inc. is one of the world’s leading manufacturers of cast and forged crankshafts. The 61 machines are operated with cooling lubricants, while some use a dry system. Consequently the extracted air is polluted with oil, emulsion or dust particles. The challenge was to operate the systems for oil and dust as energyefficiently as possible and with an automatic cleaning function. In addition to extraction of non-combustible and/or explosive dusts on 21 machines, this involved redundant wet processing for the extraction of aerosols on 16 cutting oil, 16 grinding and 8 emulsion machines. While the new filtration systems from LTA enable separated dust to be transported away in optional containers via screw conveyor and rotary valves, the cutting or grinding oils can be separated with ease with electrostatic filtration systems with integrated cleaning and then either disposed of or re-used following suitable treatment. And last but not least, this sophisticated filtration concept also permanently monitors the exhaust air values directly on the flues.

"We are very pleased with the central LTA air filtration systems, which provide extraction for the entire production line. The automatically cleanable systems provide continuous extraction for our machines with minimal maintenance expense and create a consistently clean indoor environment in the production hall."
