RailCool® Air features resource-saving heat treatment technology to optimize rail production. The focus is on an innovative cooling technique that does not require any water or chemical additives that significantly improves the rails’ mechanical load-bearing capacity and service life. Air is used instead of water as the cooling media normally used in conventional applications. RailCool® Air utilizes air-based cooling that can be powered by green energy sources. Its compact and modular design means it can be efficiently integrated into existing production facilities, setting new standards in both sustainability and performance.
