Intrinsically Safe Smartphone in Cilacap Refinery

No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.

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.

The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.

Likely candidates are refinery process units, crude and product tank farms, marine loading facilities. 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.

The complex processes crude into gasoline, diesel, kerosene, aviation fuel and LPG, plus asphalt and petrochemicals. Flammable vapour from light products and pressurised LPG are the usual concerns, but the plant defines its zones, so ask for the current classification.

With more than 85,000 maintainable assets and an ongoing safety-critical-element review, the refinery is formalising what is classified and how it is maintained. That usually means device approvals and area classification records are checked closely, so bring documentation.

The climate is hot and humid with a heavy rainy season, so devices on tank farms and jetties meet rain often. Check sealing and charging arrangements. Rain protection is separate from explosion protection, so confirm the permitted device list with the operator.
