Refinery modernisation
The modernised refinery is ramping up towards about 405,000 barrels a day, and contractors were still completing final units into late 2025 and early 2026.
Sitra is an island on the east side of Bahrain Island whose northern part is an industrial area. It hosts the Bapco Sitra refinery, whose $7 billion modernisation was inaugurated in December 2024, and the GARMCO aluminium rolling mill, so refinery and heavy-industry hazardous areas are present. This page explains what to look for in an ATEX and IECEx mobile phone for Sitra, Bahrain, 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 Sitra, Bahrain: 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. Operator approval runs on its own timeline. 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 | Sitra, Bahrain: Refinery process units, Crude and product storage, Hydrogen and hydrocracking units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Sitra. 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.
The modernised refinery is ramping up towards about 405,000 barrels a day, and contractors were still completing final units into late 2025 and early 2026.
The northern part of the island is an industrial area, with oil storage in the south and a gas pipeline link to Saudi Arabia.
East Sitra City, a reclamation project off the eastern coast, increased the island's size by about 50 percent and hosts new residential development.
Construction work on an upgrade of Bapco's Sitra refinery started in March 2019, including a new resid hydrocracking unit planned to be operational by 2023.
Sitra handles Bahrain's whole petroleum output and hosts the Port of Sitra.
The first oil infrastructure on Sitra was built in 1934 by Bapco, including a draw bridge connecting the island to Bahrain Island.
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 Sitra, Bahrain. Contractors completing final units at the modernised Bapco Sitra refinery are likely to meet reviewers who ask for certificate evidence per handset, covering both the equipment and its stated limits. A dual ATEX and IECEx route is designed to ease that for international EPCs. For the IS-04Z1 no certificate exists yet; this is work in progress.
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.
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, crude and product storage, hydrogen and hydrocracking units, sulphur recovery units. 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.
Construction of a refinery upgrade began in March 2019 and included a new resid hydrocracking unit planned for operation by 2023. Confirm the current project and commissioning status with Bapco.
Mainly the Bapco refinery and storage reservoirs, with process units, tank farms and loading facilities, plus the port. The extrusion and other light industry may have limited zones. Ask each operator for its classification drawing.
It can, because hydrogen units sit in the most demanding gas group, so the marking must cover that group. Sitra has hydrogen and hydrocracking units. Ask the operator for the classification of each unit and compare it with the device label rather than assuming one marking fits the whole refinery.
