Large multi-product site
Reduc makes more than 40 products and has a stated capacity of 239,000 barrels a day.
Duque de Caxias is an industrial municipality on Guanabara Bay about 17 km from downtown Rio de Janeiro. It hosts the Petrobras Duque de Caxias refinery (Reduc), which started up in 1961, so refining and gas-processing units create Zone 1 areas. Distribution partners for Duque de Caxias are being identified ahead of the Q4 2026 launch of the IS-04Z1.
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.
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.
| Check | What to look for | IS-04Z1 today |
|---|---|---|
| Ingress protection | IP65 to IP68 sealing | IP68 design |
| Drop and shock | A stated drop height onto concrete | Specification on request |
| Explosion protection | A separate certificate and marking | In progress; not issued |
| Where it applies | Duque de Caxias: Loading and dispatch areas, Biofuel (SAF and renewable diesel) processing, Refinery process units | Classified by the site operator |

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.
The companies on site and the hazardous-area types a handset is likely to meet there.
Reduc makes more than 40 products and has a stated capacity of 239,000 barrels a day.
Petrobras plans US$4.6 billion for Reduc in 2026-2030, with maintenance shutdowns of the coking and hydrotreating units scheduled in 2026.
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.
Reduc sells about 55 different products, the most of any Petrobras refinery, from diesel, jet fuel and asphalt to LPG, paraffins, lubricants, coke and sulphur, so many hazardous product streams are handled on site.
Petrobras has installed a reverse osmosis system supplied by SETA to treat and reuse refinery effluents, an example of the water-management projects that run alongside normal operations.
Reduc began operating in 1961 near Rio de Janeiro, one of the early refineries built after Petrobras was created in 1953 with a legal monopoly.
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Duque de Caxias. Urban setting does not remove dust, rain, humidity and coastal salt from the working day on Guanabara Bay. IP68 gives strong ingress protection for outdoor refinery use. It is not an explosion-protection rating, and the Ex marking remains what Petrobras checks at the gate.
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Duque de Caxias 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 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.
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are 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.
