Hazardous Area Mobile Phone in Cilacap Refinery

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.

Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.

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.
