Ownership has changed
Petrobras has sold some refineries (for example RLAM in Bahia and Reman in Manaus), so procurement rules differ by owner.
Petrobras' REPLAN refinery at Paulinia, Sao Paulo, is the largest in Brazil at 434,000 barrels per day, and the 208,000 b/d REPAR refinery at Araucaria, Parana, is another major site in the 2024-28 plan. Petrobras operates about ten refineries in Brazil, including Replan at Paulinia (415,000 barrels a day), Revap at Sao Jose dos Campos and Reduc at Duque de Caxias, each with classified process, storage and loading areas. If you are specifying a rugged smartphone for Brazilian refineries, this page covers the markings, the approvals and the current certification status of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Brazilian refineries: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
Current position: certification in progress, nothing issued, launch targeted for Q4 2026. 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 |
|---|---|---|
| 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 | Brazilian refineries: Hydrotreater and hydrogen units, Flare and wastewater areas, Refinery process units | Classified by the site operator |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Brazil Refineries. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
A short profile of the site and the kinds of classified area that matter for portable equipment.
Petrobras has sold some refineries (for example RLAM in Bahia and Reman in Manaus), so procurement rules differ by owner.
Refineries sit in the south-east, south, north-east and elsewhere, so logistics differ by site.
At the Gabriel Passos refinery (Regap) in Betim, Minas Gerais, capacity of 166,000 b/d is being raised by 25,000 b/d with start-up planned for 2027, and sustainable aviation fuel production is being introduced.
The Abreu e Lima refinery in Ipojuca, Pernambuco, is being expanded with a new production line to refine heavy crude from the pre-salt region.
Of eight refineries once offered for sale, only two were sold (Mataripe and the Manaus refinery), and Petrobras later resumed investing in the rest of its refining park.
The same plan allocates 2.1 billion dollars to remove logistics bottlenecks, including expanding and optimising terminals and transport infrastructure that serve the refineries.
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 Brazilian refineries. Climate varies with location across the grouping, from the humid coast to inland sites. Dust, rain and heat all occur. IP68 gives a robust ingress rating, though it does not make a handset explosion-protected. The Ex marking is what the operator inspects, so keep it legible and intact.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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, crude and product tank farms, loading racks and jetties, hydrotreater and hydrogen units. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
Refinery contractors typically check Ex certification marking, temperature class and gas group against the area classification, plus local radio approval. The detail varies by site and contractor, so confirm the requirement with the refinery safety group and your contractor induction pack.
Often. During shutdowns and revamps, work shifts between live and isolated units, and permits define which areas are gas-tested. Many sites keep the same Ex requirement for the whole fence line to avoid errors, so confirm with the operator and the turnaround contractor.
Maintenance shutdowns are a natural point, because large contractor workforces enter classified areas, and Reduc has shutdowns scheduled in 2026. Plan MDM enrolment and charging well before mobilisation. Confirm timing and rules with the site operator, as schedules change.
