Capacity
The Dumai crude unit is quoted at about 120,000 barrels per day within the 170,000 total; figures vary slightly by source.
Dumai, on the Riau coast of Sumatra, hosts Pertamina's Refinery Unit II, with Dumai and Sungai Pakning sites and a combined capacity reported at 170,000 barrels per day. Dumai is on the coast of Riau Province in Sumatra and supplies the island with gasoline, aviation fuel, diesel, kerosene and LPG, so it is a regional distribution hub as well as a processing site. An industrial smartphone distributor in Dumai Refinery, Riau would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Dumai Refinery, Riau 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.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Dumai Refinery. 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 Dumai crude unit is quoted at about 120,000 barrels per day within the 170,000 total; figures vary slightly by source.
Hot, humid equatorial conditions with rain through the year.
The Dumai refinery has operated since 1971, and the Putri Tujuh Dumai and Sungai Pakning refineries together have supplied fuel to Sumatra and contributed to regional development in Riau.
The refinery generates the power it needs from natural gas supplied by fields in South Sumatra and Jambi, including Grissik, Bentu and Jambi Merang, which cuts its fuel cost by about 40 percent.
Dumai's crude capacity is quoted at between roughly 127,000 and 170,000 barrels a day depending on the source, which places it among Indonesia's larger refineries.
Products include aviation turbine fuel, fuel oil, diesel, kerosene, solvents, LPG and green coke, so both flammable vapour and petroleum-coke dust may need consideration in area classification.
“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.
A distributor for Dumai Refinery, Riau would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
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.
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 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.
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 Dumai Refinery, Riau.
Dumai is Pertamina's Refinery Unit II and its Sungai Pakning site is managed with it. Contractors and equipment suppliers usually register through Pertamina vendor processes and the unit's own safety induction, so confirm current requirements with the refinery.
National plans to upgrade the biggest refineries mean new process areas and construction activity beside operating units. Contractors in new areas typically follow the project's hazardous-area drawings, so check the classification for your specific work front rather than assuming existing plant limits.
The unit covers Dumai and Sungai Pakning, and each site has its own areas and drawings. Rules for devices are set by Pertamina, but practical details may differ. Ask the operator for requirements covering both sites. Confirm with the site operator.
