GENERATORS FOR ZONE 2, CLASS 1 DIVISION 2, IECEx, NEC, ATEX

  • Zone 2 SD (Standard)
  • Zone 2 PT (Project)

Zone 2 SD ( Standard )

The Gen Ex Zone 2 SD Diesel Generators are designed to include components which are all certified as suitable for Zone II (G) Group II Cat 3.

The Zone 2 SD Generators are typically used for short to medium term offshore use or for mobile type applications.

EQUIPMENT

The Gen Ex Design Zone 2 SD unit is designed for mobile applications or short to medium term offshore requirements of durations up to five years. The weatherproof sound attenuated canopy is provided primarily for noise attenuation and light protection of the components within. The canopy is not designed for long term or fixed installation use in an offshore location, however all internal components are of a high IP rating and therefore they do not require weather protection.

The unit is designed as a simple standalone solution for providing portable power in a Hazardous Area, while meeting the regulatory and safety requirements of the ATEX 94/9/EC Directive.

The engine flame protection conversion includes a flame trap fitted on the exhaust outlet, this flame trap requires regular maintenance and subject to the operating load applied, this may require cleaning every two days and therefore such units are not suitable for continuous operation applications.

If the unit is required to operate on a long term continuous basis, we can offer alternative solutions to allow the removal of the flame trap while still providing a system which will meet the regulatory requirements of the applicable Hazardous Area Directives.

For Long Term Offshore requirements of ten years plus, Gen Ex Design can provide Project Specific Generator Packages designed to meet your exact requirements, for pricing and information on these please contact our sales team.
