What is a Zone 2 generator?

A Zone 2 generator is a generator adapted to run safely in a Zone 2 hazardous area: a place where an explosive gas atmosphere is not expected in normal operation and, if it occurs, lasts only a short time. The adaptations remove the engine's main ignition risks, runaway on ingested gas and hot exhaust particles, and the unit is certified for that use.

ZoneExplosive gas atmosphere is…Generator implication
Zone 0Present continuously or for long periodsNot a location for a generator
Zone 1Likely in normal operationNeeds a higher level of protection than Zone 2
Zone 2Not likely in normal operation; if present, only brieflyZone 2 converted and certified generator

The zone of a location comes from the operator's hazardous-area classification drawing, not from the equipment supplier.

How is a SINTAQA generator converted for Zone 2?

SINTAQA 1,250 kVA generator units can be converted for Zone 2 applications using the required certified safety components and project-specific modifications. Certification and documentation are prepared for the converted unit in accordance with the applicable project and client requirements. Standard fleet units are not delivered as Zone 2 by default; conversion is project-specific.

What does SINTAQA's Zone 2 package include?

The generator is converted using two ATEX-certified protective components, an air intake shutoff valve and a stainless steel exhaust spark arrestor, and an ATEX certificate is then issued for that specific SINTAQA unit, not for a generator type. Product certificates for both components come with it.

Conceptual. The final Zone 2 scope follows the site's hazardous-area classification and client requirements.

Are all generators Zone 2 certified?

No. SINTAQA 1,250 kVA generator units can be converted for Zone 2 applications using the required certified safety components and project-specific modifications. Certification and documentation are prepared for the converted unit in accordance with the applicable project and client requirements. Standard fleet units are not delivered as Zone 2 by default; conversion is project-specific. Certified SINTAQA units have already operated on client sites. Ask for the unit-specific documentation before mobilisation.

What does the site operator need to confirm?

The hazardous-area classification of the generator location, the gas group and temperature class required, and any company-specific requirements. Other measures the classification may call for, such as gas detection or requirements for cable entries and fuel equipment, are agreed per project.

  • Hazardous-area classification drawing showing the generator location
  • Gas group and temperature class required at that location
  • Required load, voltage and frequency, and whether the load is inside or outside the zone
  • Operator standards and permit requirements (for example ADNOC group company requirements)
  • Fuel tank location and refuelling arrangements

The ATEX framework is set out in Directive 2014/34/EU; area classification for gas atmospheres follows IEC 60079-10-1.

Zone 2 generators: FAQ

What is a Zone 2 generator?

A generator adapted to operate in a Zone 2 hazardous area, where an explosive gas atmosphere is not expected in normal operation and would only be present briefly. The adaptations stop the engine from becoming an ignition source: an air intake shutoff valve prevents runaway if gas is drawn in, and an exhaust spark arrestor stops hot particles leaving the exhaust.

Are all SINTAQA generators Zone 2 certified?

No. SINTAQA 1,250 kVA generator units can be converted for Zone 2 applications using the required certified safety components and project-specific modifications. Certification and documentation are prepared for the converted unit in accordance with the applicable project and client requirements. Standard fleet units are not delivered as Zone 2 by default; conversion is project-specific. Certified SINTAQA units have already operated on client sites.

Can a Zone 2 generator be used in Zone 1?

No. Zone 1 is a higher-risk classification, where an explosive atmosphere is likely in normal operation, and needs a different level of protection. The Zone 2 package described here is for Zone 2 locations only.

What documents come with a Zone 2 rental generator?

ATEX product certificates for the fitted protective components and the ATEX certificate issued for the specific converted unit. Additional documents required by the site operator, for example for a permit to work, are agreed at the enquiry stage.

Are the generators approved by ADNOC?

ADNOC-approved generator units are available for applicable ADNOC projects. ADNOC-approved fuel-tank configurations are available. ADNOC-approved components are used where required by project specifications. The air intake shutoff valves and spark arrestors used for Zone 2 conversion are ATEX- and ADNOC-approved components. Separately, sINTAQA is registered as a vendor with ADNOC.
