Pipelines
The Ruwais refinery connects to three jetties on the Gulf and a pipeline network of more than 1,600 km across the emirate for distributing fuels.
ADNOC's Ruwais complex in Abu Dhabi's Al Dhannah area is the biggest refinery in the Middle East, with Ruwais Refinery East rated at over 922,000 barrels a day and Ruwais Refinery West at up to 417,000. Process units, tank farms and jetties are classified areas. If you are specifying an ATEX and IECEx smartphone for UAE refineries, 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 UAE refineries: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Marking | II 2 G Ex ib IIC T4 on the rating plate | Design target; not yet marked |
| EU-type examination certificate | Notified body number and certificate ID | In progress with TÜV; not issued |
| IECEx certificate of conformity | Number listed on the IECEx online register | In progress; not issued |
| Where it applies | UAE refineries: Refinery process units, Tank farms, Loading jetties and gantries | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in UAE Refineries. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The companies on site and the hazardous-area types a handset is likely to meet there.
The Ruwais refinery connects to three jetties on the Gulf and a pipeline network of more than 1,600 km across the emirate for distributing fuels.
ADNOC's older Abu Dhabi Refinery on Umm Al Nar Island, which processed up to 85,000 barrels a day, was shut in 2022 as ADNOC focused its downstream strategy on Ruwais.
A condensate splitter typically yields about half naphtha, 30 per cent jet fuel and 10 per cent gas oil, so light, easily ignited products dominate the process units.
UAE phones need type approval from the federal Telecommunications and Digital Government Regulatory Authority, and refinery operators add their own approval rules for portable devices.
Ruwais Refinery West opened in 2014 with 417,000 barrels a day and contains a very large residue catalytic cracking unit that upgrades about 127,000 barrels a day of heavy residue into middle distillates.
ENOC opened its first oil refinery in 1999 at 120,000 barrels a day for about 1.5 billion dirhams, so Dubai's refining is much younger than Abu Dhabi's.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In UAE refineries. ADNOC's refining operations at Ruwais and Umm Al Nar are the main buyers here, so a reviewer would look for certificate numbers, markings and schedules of conditions for devices in process units and tank farms. A dual ATEX and IECEx route also helps turnaround contractors from abroad. The IS-04Z1 certificates are in progress.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Likely candidates are refinery process units, tank farms, loading jetties and gantries, product 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.
No. ADNOC runs the Ruwais complex in Abu Dhabi, but Dubai's Jebel Ali refinery is run by ENOC Processing Company, a subsidiary of the Dubai government's energy group, and smaller plants operate at Fujairah. Each operator has its own supplier and equipment-approval process.
That depends on the project owner. ADNOC, ENOC and the Fujairah operators run separate procurement and HSE processes, so there is no single approval. Ask the client or main contractor which operator's standards apply, and check current requirements directly with that operator.
It groups ADNOC's Ruwais complex, the largest, and a smaller refinery at Umm Al Nar in Abu Dhabi. Current operating status of individual units has not been checked here. Ask ADNOC refining which units are active, and which areas your team will actually enter.
