The 7,000,000 square-foot facility of AM/NS Calvert—a joint venture between ArcelorMittal and Nippon Steel Corporation—is one of the most advanced steel finishing facilities in the world. It produces a broad portfolio of steel grades for high-value applications, including hot-rolled bands, hot-rolled pickled and oiled, cold-rolled, and advanced coated products. Instrument-quality compressed air is used for a variety of production equipment and processes.
Catastrophic failure of an older air compressor meant the plant had to rent a compressor for a costly monthly rental fee, plus expensive diesel fuel.
A matrix of requirements for a new compressor was developed, but the plant’s hands were tied because the replacement would have to fit a tight footprint and limited power availability.
A two-stage Kaishan KRSP2-500, water-cooled rotary screw air compressor met the matrix of requirements. The design fit the footprint and power limitations, plus provided valuable maintenance advantages.
“For our 24/7 operation, the KRSP2 two-stage rotary air compressor has been running like a champ. It’s a winner for efficiency, sound level, maintenance and footprint. Plus, it came with a lifetime airend warranty, including training, which moved it far ahead of competitors.”
