Ex-Proof Smartphone Distributor in Singapore Refinery
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. An Ex-proof smartphone distributor in Singapore refineries would carry the IS-04Z1 to these buyers once certification completes.

The term · Ex-proof
What “Ex-proof” means for a smartphone
“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 Singapore refineries. Process units, tank farms and jetties are described as Zone 1 and Zone 2 areas here. Hydrocarbon fuels usually fall in gas groups IIA or IIB, though hydrogen units can need IIC. The IS-04Z1 target marking is II 2 G Ex ib IIC T4, not yet issued, so the operator's drawings decide fit.

Distributing the IS-04Z1 in Singapore Refinery
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Singapore refineries yet and applications are reviewed company by company. Because a certified Ex device cannot be opened by an ordinary phone workshop without invalidating its certificate, SAMS looks for partners who can provide competent technical support and after-sales service locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Singapore refineries.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Singapore Refinery
Frequently asked questions
Can we buy an Ex-proof smartphone in Singapore Refinery today?
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.
What does an Ex-proof smartphone in Singapore Refinery cost?
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.
What Ex marking will the IS-04Z1 carry?
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.
Which areas at Singapore refineries would use it?
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.
How do I become a SAMS distributor for Singapore refineries?
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.
Can I use a phone inside a Singapore refinery?
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.
What does a refinery visit involve in practice?
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.
Do hydrogen units change the marking needed?
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.
