Frequently Asked Questions

LNG plants require explosion proof lighting certified for gas group IIC, which covers methane (the primary component of LNG) as well as hydrogen and acetylene — the most challenging gas groups for hazardous area equipment. Gas group IIC is a higher requirement than IIA and IIB, and not all explosion proof luminaires are certified for IIC. Raytec SPARTAN LED luminaires supplied by AJV Tech carry IECEx and ATEX certification for gas group IIC and are specified across QatarEnergy, ADNOC, and other LNG operator facilities.

In areas where ambient temperatures can fall significantly below zero — such as near LNG cold boxes, liquefaction trains, and LNG storage tank bunds — explosion proof fixtures must be rated for cryogenic temperature operation. Standard explosion proof luminaires are typically rated for operation down to -20°C or -40°C, and specific LNG applications may require confirmation of the lower operating temperature. AJV Tech can advise on Raytec SPARTAN model selection for LNG areas with extreme low-temperature requirements.

Lux level requirements for LNG plant working areas depend on the task type and operator standards, but typically range from 50 lux for general area access and walkways to 200-500 lux for instrumentation and valve platforms, and up to 500-1000 lux for control room exteriors and high-activity maintenance areas. QatarEnergy, ADNOC LNG, and other operators have specific lighting design standards. AJV Tech provides photometric lighting design services to verify lux compliance for LNG plant installations.

Yes. AJV Tech supplies IECEx and ATEX certified explosion proof lighting to QatarEnergy LNG facilities in Ras Laffan, including Raytec SPARTAN gas group IIC luminaires for fixed Zone 1 and Zone 2 installations, and Atexor portable lighting systems for shutdown and maintenance operations. Products are supplied with complete IECEx documentation for QatarEnergy technical submittals. UAE stock allows rapid delivery to Qatar for shutdown mobilisation requirements.

Ramfan ATEX/IECEx certified explosion proof blowers are used during LNG and gas processing plant shutdowns for confined space ventilation, vessel purging, and gas clearance prior to hot work. The blowers provide high-volume airflow in Zone 1 classified environments and are suitable for use in LNG plant areas certified for gas group IIC. AJV Tech can supply combined shutdown lighting (Atexor) and ventilation (Ramfan) packages for LNG and gas processing turnarounds.
