Climate
Hot, humid Gulf coastal climate; outdoor equipment should resist heat and salt air.
Outside Abu Dhabi, the Jebel Ali refinery in Dubai is run by ENOC Processing Company, a subsidiary of ENOC, the Dubai government's energy group established in 1993. Process units, tank farms and jetties are classified areas. This page explains what to look for in an Ex-proof mobile phone for UAE refineries, and where the IS-04Z1 stands against that list today.
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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. 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 |
|---|---|---|
| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |
| Temperature class | T-class below the ignition temperature of the gas | T4, 135 °C (target) |
| 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.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Hot, humid Gulf coastal climate; outdoor equipment should resist heat and salt air.
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.
One published refinery list gives the Jebel Ali refinery a capacity of 140,000 barrels a day, showing that it is a mid-sized plant compared with the Ruwais complex.
ADNOC's Ruwais Refinery East can process up to 922,000 barrels a day of crude and condensate, the largest refinery in the Middle East, and is closely integrated with other plants in the Ruwais industrial area.
The same list shows smaller Fujairah plants of 80,000, 7,500 and 70,000 barrels a day, so refining sites are scattered across the east coast as well as the Gulf.
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.
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In UAE refineries. A marking check at a refinery would compare each unit's zone, gas group and temperature class with the device marking. Process units, tank farms and loading jetties handle different products. The IS-04Z1 target is II 2 G Ex ib IIC T4, still in progress; ADNOC decides what it accepts.
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 marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
