It contains in aqueous solution a combination of glycols of different chain lengths as well as special additives for wear resistance as well as corrosion protection etc. ULTRA-SAFE 620 is applied in all areas where the risk of a fire hazard exists, as the steel industry in forging shops, heat treatment shops, casting shops – especially in die casting shops – in coal mines, but it is also used in applications where a good biological degradability of the hydraulic fluid is important. ULTRA-SAFE 620 fulfil all requirements of the 7 th Luxemburg Report and is approved.
