Dalkia Industry CZ a.s. recently completed a multi-year process of replacing their compressed air equipment with latest technology from Atlas Copco. The modernized compressed air system offers higher safety, lower energy consumption along with a sophisticated control system, energy recovery capability and low maintenance.
In 2005, when Dalkia Industry CZ replaced the first turbocompressor at one of their mines, it literally set off an avalanche. "In just six years, Atlas Copco machines replaced the old turbocompressors on all of Dalkia’s 9 active mines," says Francesco Pinna, General Manager of Atlas Copco Compressors, Czech Republic. The 20th and last compressor has recently been ceremonially put into operation. Atlas Copco delivered the equipment as complete and integrated packages, equipped with all components, internal pipe systems and connections. Annually, Dalkia can produce 2.4 billion cubic meters of compressed air for the miners there.
"The main requirement is large and stable output, a pressure of 4 to 4.5 bar at a temperature below 60°C," says Laurent Tupinier, CEO of Dalkia Industry CZ, adding: "For work in mine shafts, compressed air is absolutely key for operational and safety reasons.
