Spread across regions
Refineries sit in the south-east, south, north-east and elsewhere, so logistics differ by site.

ATEX and IECEx Smartphone in Brazil Refineries
This is a regional grouping rather than a single site. 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. This page explains what to look for in an ATEX and IECEx smartphone for Brazilian refineries, and where the IS-04Z1 stands against that list today.

Turnaround cycles
Planned maintenance shutdowns bring large contractor workforces into classified areas; Reduc, for example, has shutdowns scheduled in 2026.

Brazilian refineries: projects and investment
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.
Brazilian refineries: who works there
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.
Brazilian refineries: who works there
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.
Brazilian refineries: logistics and access
The same plan allocates 2.1 billion dollars to remove logistics bottlenecks, including expanding and optimising terminals and transport infrastructure that serve the refineries.
The term · ATEX and IECEx
What “ATEX and IECEx” means for a smartphone
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Brazilian refineries. Across Petrobras refineries such as Replan, Revap and Reduc, an HSE reviewer will want certificate evidence tied to Brazil's Inmetro-accredited certification route. A dual ATEX and IECEx route is designed to help international engineering firms during projects. The IS-04Z1 has no certificate yet.

Specifying an ATEX and IECEx smartphone for Brazil Refineries
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · Brazil Refineries
Frequently asked questions
Can we buy an ATEX and IECEx smartphone in Brazil Refineries today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an ATEX and IECEx smartphone in Brazil Refineries cost?
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.
Is the IS-04Z1 ATEX and IECEx certified?
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
Which areas at Brazilian refineries would use it?
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.
Is intrinsically safe the same as explosion proof?
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.
How are devices usually approved for Petrobras refineries?
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.
Do refinery turnarounds change the device requirements?
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.
When is the best time to deploy handsets at a refinery?
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.
