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. Crude processing, storage and marine loading create Zone 1 areas. An explosion proof 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. 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 |
|---|---|---|
| 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 | Dumai Refinery, Riau: Refinery process units, Crude and product tank farms, Marine loading jetties | Classified by the site operator |

A short profile of the site and the kinds of classified area that matter for portable equipment.

Fortune Indonesia reports the unit has been operating since 1971 and spans Dumai and Sungai Pakning, with products including LPG, jet fuel, diesel and green coke.
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.
All six of Indonesia's oil refineries are run by Pertamina, and together they supplied only about half of national fuel demand, which is why upgrade programmes cover the largest units including Dumai.
Indonesia's Refinery Development Master Plan aims to raise national crude processing capacity towards two million barrels a day, with the biggest existing refineries to be upgraded and new ones built at Tuban and Bontang.
Dumai lies about 188 km from Pekanbaru and is connected to the Trans-Sumatra Highway and toll road; Pinang Kampai Airport has daily domestic flights to Jakarta, Pekanbaru, Medan and Batam.
“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 Dumai Refinery, Riau. Across Dumai's process units, tank farms and jetties, explosion-proof is everyday shorthand. Flameproof Ex d serves fixed equipment, whereas a handheld carried between units relies on intrinsic safety. Products such as LPG and jet fuel are classified by the operator, who decides the accepted concept.
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 yet. The IS-04Z1 is pre-launch and its certification is still in progress ahead of a Q4 2026 launch. No unit goes into a classified area before the certificate covering it exists. The datasheet, the certification schedule and safe-area evaluation units are available now.
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.
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 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.
