Planetary gearboxes are ATEX compliant

A Brevini product story
Edited by the Engineeringtalk editorial team Jun 15, 2004

A new range of ATEX compliant planetary gearboxes is suitable for zones where explosive atmospheres may occur, and also zones characterised by the presence of gas mixtures and/or combustible powders.

Brevini Riduttori has introduced a range of ATEX compliant planetary gearboxes suitable for applications in zones where explosive atmospheres may occur, and also zones characterised by the presence of gas mixtures and/or combustible powders (zones 1, 2, 21, 22).

To ensure compliance, every Brevini ATEX gearbox undergoes a special painting cycle, which avoids the problem of electrostatic discharge, and is supplied with a specific user instruction manual and conformity statement according to CEE94/9/CE Directive, Enclosure VIII.

The ATEX compliant gearboxes are flange-mounted units from Brevini's ED (two-stage), ET (three-stage) and EQ (four-stage) series.

Supplied with splined female outputs, these gearboxes are designed for a wide range of industrial and processing applications, providing nominal torque up to 8500Nm, transmission ratios up to 3.300iN and output power up to 50kW.

In common with Brevini's standard series planetary gearboxes, the ATEX compliant units are designed to a flexible modular system, which allows the planetary stages to be combined easily, to match the increasing torque being transmitted through a gearbox.

The ATEX gearboxes also provide the operating advantages of the traditional planetary design - high efficiency (97% per stage) low weight, compact size, and low maintenance.

These advantages translate into benefits for the industrial gearbox user, in terms of increased competitiveness and reduced cost.

Commenting on the launch of the new ATEX gearboxes, Brevini's Lorenzo Federici said: "The arrival of ATEX in 2003 focused everyone's attention on the electrical aspects of the new directive, the potential for ignition in hazardous areas from mechanical sources being ignored by many companies - Brevini not among them".

"Our gearboxes are used widely in chemical processing, marine and petrochemical applications, so we are aware of the dangers in these environments and have taken the necessary measures to ensure that our gearboxes can to deal with them".
