ExxonMobil
ExxonMobil states it owns and operates a 592,000-barrel-per-day refinery integrated with its chemical plant, with three cogeneration facilities producing around 440 MW.
Singapore's crude refining is run by ExxonMobil, Singapore Refining Company and Aster, with facilities on Jurong Island and Pulau Bukom. Process units, tank farms and jetties create Zone 1 and Zone 2 areas. Distribution partners for Singapore refineries are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Singapore refineries has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Singapore refineries: Jetties, Utility and cogeneration areas, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Singapore Refinery. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Singapore Petroleum Company holds a 50% interest in SRC, whose refinery can process 290,000 barrels of crude per day; Chevron holds the other 50%.
Pulau Bukom has been home to Singapore's first oil refinery since 1961, and Aster's Bukom complex continues to refine crude alongside ethylene production.
The organisation includes dedicated functions for process safety, reliability and maintenance, and procurement and warehouse, which are the usual contacts for contractors and equipment suppliers.
The refinery's published rules state that mobile phones and other electrical or electronic equipment must not be used in the process plant area or other classified hazardous areas.
Jurong Rock Caverns store crude oil, condensate, naphtha and gasoil underground nearby, supporting feedstock flexibility for refiners on Jurong Island.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Singapore refineries. Refinery sites on Jurong Island and Bukom are hot, humid and exposed to sea breezes, and jetty work adds spray and rain. IP68 sealing is designed in for the IS-04Z1 and suits it. That is a dust and water rating, not explosion protection, which depends on Ex certification now in progress.
A distributor for Singapore refineries would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
Likely candidates are refinery process units, crude and product storage, jetties, utility and cogeneration areas. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Singapore refineries.
One refinery on Jurong Island publishes a ban on mobile phones and other electrical or electronic equipment in its process plant and classified hazardous areas. Devices certified for the zone may be allowed only with prior approval, so ask your sponsor before the visit.
Typically a visitor pass at the island checkpoint, a plant security pass, an indemnity form, security screening, declaration of electronic equipment and an escort by a named sponsor for the whole visit. Allow extra time at the gate and arrive with approved paperwork.
Hydrogen is a Group IIC gas, so any unit handling it can call for IIC equipment, whereas many fuels fall in IIA or IIB. The IS-04Z1 target marking includes IIC but is not yet issued. Ask the refinery which units hold hydrogen.
