Crude supply
The project includes a single point mooring for very large crude carriers and two one-million-barrel crude tanks at Lawe-Lawe.
Balikpapan in East Kalimantan is the site of Pertamina's Refinery Unit V, operated by PT Kilang Pertamina Balikpapan. Oil drilling began at Balikpapan on 10 February 1897, a date now used as the city's anniversary, and the Dutch company BPM made the town its headquarters in 1907, so petroleum has shaped the place for well over a century. An intrinsically safe smartphone distributor in Balikpapan, East Kalimantan would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Balikpapan, 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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Level of protection | ia, ib or ic matched to the zone | ib, for Zone 1 |
| Entity parameters | Uo, Io and Po within the device limits | Published with the certificate |
| Accessories | Chargers and cases certified with the device | Defined at certification |
| Where it applies | Balikpapan, East Kalimantan: Crude and product storage, Marine crude mooring and tanks, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Balikpapan. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Who operates there and which kinds of classified area a handset would meet, from the SAMS site research.
The project includes a single point mooring for very large crude carriers and two one-million-barrel crude tanks at Lawe-Lawe.
Hot, humid equatorial conditions with rain through the year.
The Balikpapan and Lawe-Lawe Refinery Development Master Plan raised crude capacity from 260 to 360 thousand barrels a day and added a 90 thousand barrel a day residue catalytic cracking unit.
The refinery operator says it relies on technical staff with decades of petroleum-processing experience and works within Pertamina Group standards, so contractor induction typically follows Pertamina procedures.
The city has the largest economy in Kalimantan by GDP and is served by Sultan Aji Muhammad Sulaiman Sepinggan Airport, with Semayang as its main seaport, the second busiest in East Kalimantan.
Balikpapan is a seaport city on the east coast of Borneo and the financial centre of Kalimantan, with about 757,000 residents in 2023, making it the second most populous city in East Kalimantan.
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Balikpapan, East Kalimantan. With a new residual cracking unit and a naphtha unit being added, there will be commissioning walk-downs and startups across the refinery. A handheld intended for intrinsic safety could carry checklists and photos through those rounds. That use depends on certification and on Pertamina's acceptance.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Balikpapan, 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.
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, residual fluid catalytic cracking unit, crude and product storage, marine crude mooring and tanks. 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 Balikpapan, East Kalimantan.
Refinery Unit V is run by PT Kilang Pertamina Balikpapan, part of the Pertamina group. Contractors and suppliers normally register through Pertamina's vendor processes and follow the site's own permit and induction rules, so confirm the current route with the plant.
Yes. The upgrade added a residue catalytic cracking unit and raised capacity by 100 thousand barrels a day beside the existing units, so area classification drawings can differ between revamped and legacy sections. Ask for the current hazardous-area drawings for the unit you will work in.
Possibly, because new units bring new classified areas and contractor equipment rules. The operator sets the requirements for each phase. Ask Pertamina or its contractors for current device approval procedures and do not assume earlier approvals cover new areas. Confirm with the site operator.
