The term · industrial

What “industrial” means for a smartphone

“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.

The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.

In Dumai Refinery, Riau. The unit spans two sites, so a device fleet may need consistent MDM or EMM enrolment across both, with a charging point in a safe area at each. Contractors working on products such as green coke and LPG may also need access. Check network coverage per site.

Questions · Dumai Refinery

Frequently asked questions

Can we buy an industrial smartphone in Dumai 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 industrial smartphone in Dumai Refinery cost?

No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.

Is the IS-04Z1 an industrial phone as well as an Ex phone?

Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.

Which areas at Dumai Refinery, Riau would use it?

Likely candidates are refinery process units, crude and product tank farms, marine loading jetties. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.

Is intrinsically safe the same as explosion proof?

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.

Does green coke at Dumai create a dust hazard for electronics?

Green coke is a petroleum-coke product, and fine carbon dust can be combustible and conductive. Where it is handled, sites may classify combustible-dust zones, so ask the operator whether your handset needs a dust-rated device and how often it must be cleaned.

Is Dumai reachable for equipment shipments?

Dumai is a coastal port city in Riau Province, so sea freight is practical, and many visitors fly to Pekanbaru and continue by road. Plan for customs clearance in Indonesia and a site gate check, and confirm lead times with your freight agent.

Is Dumai's humidity a problem for a handset?

Equatorial heat and rain through the year affect battery performance and seals, so check the rated operating range and charging arrangements. Charge only in safe areas. Rain protection does not equal explosion protection. Confirm the permitted device list with the operator.
