Climate
Hot, humid equatorial conditions on the East Kalimantan coast.
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. Liquefaction, storage and loading create Zone 1 areas. An explosion proof smartphone distributor in Bontang LNG (Badak LNG), East Kalimantan would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Bontang LNG (Badak LNG), East Kalimantan has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Protection concept | Flameproof (Ex d) or intrinsic safety (Ex i) | Intrinsic safety, level ib |
| Zone suitability | Zone 1 gas and Zone 21 dust | Design target for Zone 1 and 21 |
| Certificate | Number, issuing body and schedule of conditions | In progress; not issued |
| Where it applies | Bontang LNG (Badak LNG), East Kalimantan: Gas pipelines, Loading jetties, LNG liquefaction trains | 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.
The companies on site and the hazardous-area types a handset is likely to meet there.
Hot, humid equatorial conditions on the East Kalimantan coast.
The company was established in 1974 and the first train was completed on 5 July 1977.
Bontang grew from a village into an industrial city after Badak LNG was founded in 1974 and Pupuk Kaltim three years later, and it became an autonomous city in 1999.
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.
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.
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In Bontang LNG (Badak LNG), East Kalimantan. Around liquefaction trains and storage tanks, explosion-proof is a casual term. Flameproof Ex d enclosures suit fixed equipment, while a handheld carried along pipework or tanks relies on intrinsic safety. Methane and LPG areas are classified by the operator, which determines the accepted concept for each place.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Bontang LNG (Badak LNG), East Kalimantan 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.
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.
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.
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is 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.
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 Bontang LNG (Badak LNG), East Kalimantan.
Yes. The same city hosts a large fertiliser complex making ammonia and urea, plus coal mining operations nearby. That gives gas, toxic-gas and dust risks within a short distance, so check which area type and which operator rules apply to your task.
Bontang has a private airport run by Badak NGL and the Loktuan seaport, but many visitors route through Balikpapan or Samarinda and travel by road. Plan extra time for customs clearance and for gate checks on electronic devices.
It can, because idle trains may be under different isolation and permit rules, and reactivation brings contractor crews back. Requirements follow the operator's current classification, so ask PT Badak NGL which areas are live. Confirm with the site operator before planning any trial.
