9.1 General Information
Directive relates not only to electrical equipment, but also to all kind of machines and control components, separately or
jointly, for use in potentially explosive atmospheres.
The following recommendations, issued to operations in potentially explosive environment, are meant as specific
completion to general-purpose «Working instructions».
VARVEL-ATEX gearboxes and variators are manufactured with housings and covers of metallic material, incorporating
the transmission elements fitted on ball and roller bearings, with Viton oilseals on input and output shafts et with the
adequate oil quantity to assure the design operation.
9.2 Prevalent Use
VARVEL-ATEX gearboxes and variators are identified like « components », fundamental but without any autonomous
function to operate units and protection systems for production, transport, storage, measurement, control and conversion
of energy, or the processing of materials which are capable of causing an explosion through their own potential source of
ignition.
