ET 25 + TA

TA Roloff drives can also be used to automate valves located in system areas where explosive atmospheres from gases or vapors arise. In these areas, with every electric drive, there is a risk that the explosive atmosphere will penetrate into the drive, ignite due to spark formation (when the ignition temperature is reached) and escape through gaps (so-called ignition penetration capability), which could result in an explosion in this area of the system with corresponding consequences This can result in property damage and personal injury. In these areas of the system, special design precautions must therefore be taken with electric drives to prevent the drive from being an ignition source for the ambient atmosphere in the manner described. The fact that these precautions actually exist is proven for all TA-Roloff products not only by the manufacturer's declaration, but also by type tests according to the so-called ATEX guidelines and by test certificates from recognized certification bodies (IBExU, UL DEMKO).

ET 25 on & inside

The device category 2 (“2G”), as TA-Roloff is allowed to show on the nameplate, always requires passed type tests according to the so-called ATEX guidelines and is proven by test certificates from recognized certification bodies (IBExU, DEMKO). In addition, there are annual reviews and audits of these organizations. The Ex approval of your system will therefore be carried out without any problems when using TA-Ex products. Mere manufacturer declarations that are sufficient for device category 3 (“3G”) and for the use of the Ex symbol are only as good as the manufacturer. Drives in category 3 G may only be used if explosive atmospheres can only arise “rarely and for a short time”. Don't buy into uncertainties, but rather adequate, tested drive technology from TA Roloff.
