Non-sparking coupling is Atex-certified

09 June, 2015

The German manufacturer KTR has developed a coupling for use in potentially explosive atmospheres. Its Rotex Non-Sparking coupling uses a newly-developed conductive plastic which is injected into the hub of the coupling to produce a device that is said to be failsafe and maintenance–free.

KTR says that the technology could open up new Atex applications ­­– such as compact designs with necked-in hubs – as well as being used to produce customised shaft-cam links.

The new coupling is Atex-certified and is claimed to offer good dynamic properties and a low moment of inertia. It dampens torsional vibration during power transmission and absorbs shocks resulting from unbalanced machinery. It is available in single or double cardan designs that can accommodate large shaft misalignments.

Torque will continue to be transmitted, without any risk of sparking, even of the spider element becomes worn, allowing maintenance to be delayed to a convenient time.
