Refining scale
ADNOC rates Ruwais Refinery East at over 922,000 barrels a day, making it the world's fourth-largest single-site refinery; Ruwais Refinery West, opened in 2014, is rated at up to 417,000 barrels a day.
Ruwais, in Al Dhannah on Abu Dhabi's western coast, hosts ADNOC's refining complex, the UAE's only natural gas liquids fractionation plant and the Borouge polyolefins plants. The TA'ZIZ chemicals zone is being developed alongside them, adding new classified areas. If you are specifying an intrinsically safe smartphone for Ruwais industrial complex, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Ruwais industrial complex: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Ruwais industrial complex: Refinery process units, NGL fractionation, Polyolefin plants | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Ruwais Petrochemical. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
ADNOC rates Ruwais Refinery East at over 922,000 barrels a day, making it the world's fourth-largest single-site refinery; Ruwais Refinery West, opened in 2014, is rated at up to 417,000 barrels a day.
TA'ZIZ plans 4.7 million tonnes a year of chemicals by the end of 2028; a dedicated chemicals port is scheduled for completion in the fourth quarter of 2026, and a 27-year utilities agreement with TAQA was announced in January 2026. These are plans, not completed facilities.
UAE mobile phones are type-approved by the Telecommunications and Digital Government Regulatory Authority, which has added advanced mobile location testing to mandatory phone tests.
The industrial and housing complex was planned in the 1970s around the Ruwais Refinery and inaugurated in 1982; a hydrocracker was added in 1985, so units span several decades.
The Ruwais Housing Complex covers 6 square km and sits 10 km from the plants, with its own shops, schools, banks, mosques and clinic, so most staff commute each day.
The housing complex has grown beyond oil and gas staff to include government workers on nearby projects such as the Barakah nuclear power plant.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Ruwais industrial complex. Rounds across refinery units, fractionation, polyolefin plants and jetties involve many Zone 1 stops, and a new chemicals zone adds commissioning walkdowns. A handheld intrinsically safe device lets inspectors record readings and photograph equipment on the spot, which the IS-04Z1 is designed to support.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Likely candidates are refinery process units, ngl fractionation, polyolefin plants, marine jetties and fuel pipelines. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Ruwais, or Al Dhannah, is 240 km west of Abu Dhabi city, so visiting teams normally travel by road for several hours or stay locally. The housing complex is 10 km from the plants, so plan daily transfer and gate times.
Mostly in the Ruwais Housing Complex, which covers about 6 square km and is 10 km from the industrial plants, with shops, schools and a clinic. Some government workers on nearby projects also live there, so gate and transport times can be busy.
Ruwais is hot and humid, and salt air affects outdoor equipment. The IS-04Z1 is designed to IP68 with a 4,000 mAh battery, but no heat or salt limits have been published. Ask for the datasheet and agree outdoor-use conditions with the operator.
