History
The company was established in 1974 and the first train was completed on 5 July 1977.
Bontang hosts the Badak LNG plant, owned by Pertamina and run by PT Badak NGL. It has eight liquefaction trains with a design capacity of 22.5 million tonnes a year, though only a few are in service. Liquefaction, storage and loading create Zone 1 areas. If you are specifying an industrial mobile phone for Bontang LNG (Badak LNG), East Kalimantan, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Bontang LNG (Badak LNG), East Kalimantan: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP rating for dust and water | IP68 design |
| Fleet management | EMM and MDM support | Android 16 with EMM and MDM |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Bontang LNG (Badak LNG), East Kalimantan: LNG liquefaction trains, LNG and LPG storage tanks, Gas pipelines | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Bontang LNG. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
The company was established in 1974 and the first train was completed on 5 July 1977.
Declining feed gas has cut output since 2001. Reporting in 2025 put only two trains in operation, with reactivation of Train F targeted for October 2028 as new gas arrives.
Bontang has a tropical rainforest climate with warm, stable temperatures and abundant rain, a drier period from about May to September and a wetter one from November to May.
Coal mining company PT Indominco, owned by Banpu and active since 1977, extracts up to 11 million tonnes a year, so Bontang combines gas liquefaction, ammonia and coal dust hazards in one small city.
Bontang sits on the Makassar Strait coast of East Kalimantan and has only 160 sq km of land, of which about 32 percent of its administrative area is dry land, so industrial sites sit close to the sea and town.
Bontang Industrial Technology College (STTIB) is the city's best known higher education institution, supplying local technicians for the gas, fertiliser and coal industries.
“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 Bontang LNG (Badak LNG), East Kalimantan. Output has been reduced for years and only a few trains run, so the workforce and device fleet are shaped by that. Reactivation plans would bring contractors back. MDM or EMM enrolment, safe-area charging and reliable site connectivity should be planned for before any rollout.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
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.
Likely candidates are lng liquefaction trains, lng and lpg storage tanks, gas pipelines, loading jetties. 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 main ones are LNG and natural-gas processing areas, ammonia and urea plants, and coal handling with combustible dust. Each operator classifies its own plant, so ask Badak LNG, Pupuk Kaltim or the mine for its zone drawings before bringing handheld devices on site.
Yes. A tropical rainforest climate with frequent heavy rain, warm stable temperatures and sea air tends to stress seals, connectors and chargers. Typically users specify good ingress protection and keep spare batteries and cleaning routines, subject to the plant's rules.
Jetties and coastal areas expose devices to heat, humidity and salt air. Check the rated temperature range, seals and charging contacts. Charge only in safe areas. Water and dust protection does not replace explosion protection. Confirm site practice with the operator.
