Investment programme
Petrobras plans US$4.6 billion for Reduc in 2026-2030, with maintenance shutdowns of the coking and hydrotreating units scheduled in 2026.
Duque de Caxias is an industrial municipality on Guanabara Bay about 17 km from downtown Rio de Janeiro. Reduc is listed among the Petrobras refineries receiving modernisation (revamp) projects in the company's refining investment portfolio, alongside Replan and the Presidente Bernardes refinery. An intrinsically safe mobile phone distributor in Duque de Caxias would carry the IS-04Z1 to these buyers once certification completes.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. Duque de Caxias 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. Operator approval runs on its own timeline. 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 |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Duque de Caxias. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.

Petrobras plans US$4.6 billion for Reduc in 2026-2030, with maintenance shutdowns of the coking and hydrotreating units scheduled in 2026.
The refinery sits in the dense Rio metropolitan area with road links to the city and airport.
The Reduc delayed coking unit started operating in July 2008 after an investment of about one billion dollars, converting heavy feedstock into diesel and naphtha and producing petroleum coke.
A natural-gas power unit of 63 MW has served the refinery since 1976, so the site generates part of its own electricity as well as processing fuels and lubricants.
The Duque de Caxias refinery (Reduc) has operated since 1961, ranks among Brazil's largest by crude capacity, and supplies about 80 percent of the country's lubricants while leading natural gas processing.
The Duque de Caxias refinery complex covers about 13 square kilometres beside Rodovia Washington Luis in the Campos Eliseos district, making it a very large industrial site inside the Rio de Janeiro metropolitan area.
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 Duque de Caxias. Maintenance shutdowns of the coking and hydrotreating units are scheduled in 2026, and shutdown walkdowns need handhelds that can safely enter process units. Intrinsic safety suits those inspections. The IS-04Z1 is designed for such use and is awaiting certification.
A distributor for Duque de Caxias 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.
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, tank farms and pipelines, loading and dispatch areas, biofuel (saf and renewable diesel) processing. 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 Duque de Caxias.
Typically choose a device with the right zone, gas group and temperature class, carry its certificate, and confirm local radio approval requirements. Many sites also require induction and an approved-equipment check at the gate, so allow time for that.
Lubricant plants and gas processing mean both flammable liquids and flammable gases can occur, sometimes with hydrocarbon vapours near ambient temperature. Ask the operator for the applicable gas groups; do not assume one device rating covers every unit.
Maintenance shutdowns of the coking and hydrotreating units are scheduled in 2026, which brings large contractor numbers into classified areas. Plan lead times early. Certification is in progress, so confirm schedules and requirements with the site operator and its HSE team.
