RDMP upgrade
The Jakarta Post reported that the new residual fluid catalytic cracking unit was due to start in November 2025, with a naphtha unit following in mid-2026.
Balikpapan in East Kalimantan is the site of Pertamina's Refinery Unit V, operated by PT Kilang Pertamina Balikpapan. The RDMP upgrade is raising capacity from 260,000 towards 360,000 barrels per day, so process units and tank farms are Zone 1 areas. Distribution partners for Balikpapan, East Kalimantan are being identified ahead of the Q4 2026 launch of the IS-04Z1.
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. Operator approval runs on its own timeline. Certification status. Place facts reviewed October 2026.

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 Jakarta Post reported that the new residual fluid catalytic cracking unit was due to start in November 2025, with a naphtha unit following in mid-2026.
The project includes a single point mooring for very large crude carriers and two one-million-barrel crude tanks at Lawe-Lawe.
Indonesia's six large refineries are Cilacap, Balikpapan, Dumai, Musi, Balongan and Tuban, and the country imported about 787 thousand barrels a day of petroleum products in 2024, so reliability work at Balikpapan matters nationally.
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.
After the upgrade the refinery can make fuel to Euro 5 standard, and it sits alongside Cilacap as one of Indonesia's two largest refineries, so new process units stand beside older ones in the same complex.
Pertamina took over the area's oil operations from Shell in 1965, and the refinery is now run by PT Kilang Pertamina Balikpapan, formed in 2019 to operate Refinery Unit V on an operation and maintenance basis.
IECEx is the international scheme for certifying equipment used in explosive atmospheres. A certificate of conformity is issued by an accredited certification body against a specific edition of the IEC 60079 standards and carries a schedule of conditions of safe use. It is not a legal requirement in most countries on its own, but many national schemes accept it as the technical basis.
The IECEx certificate for the IS-04Z1 is in progress and has not been issued. The marking target is Ex ib IIC T4, the intrinsic safety concept for Zone 1 gas with the hardest gas group (IIC) and a 135 °C temperature class.
In Balikpapan, East Kalimantan. The RDMP upgrade brings contractors used to the IECEx scheme into a Pertamina site. A certificate of conformity and its schedule of conditions would be the shared reference. For the IS-04Z1 those documents are targets, not issued, so they cannot yet support any purchase.
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Balikpapan, East Kalimantan. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device 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.
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.
No. The IECEx certificate is in progress and has not been issued. SAMS will publish the number when it exists.
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.
