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

Ex-Proof Mobile Phone Distributor 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. An Ex-proof mobile phone distributor in Brazilian refineries would carry the IS-04Z1 to these buyers once certification completes.

WhereBrazil Refineries
Short answer. Brazilian refineries 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.

Brazilian refineries: projects and investment
Revamp projects are under way at the Presidente Bernardes (RPBC), Paulinia (Replan) and Duque de Caxias (Reduc) refineries, with hydroprocessing units planned at Revap and Refap.
Brazilian refineries: projects and investment
Under the Strategic Plan 2024-28+ Petrobras budgets 16.7 billion US dollars across refining, transport and marketing, with 9 billion dollars earmarked for refining, which implies a long pipeline of shutdown and revamp work.
Brazilian refineries: who works there
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.
Brazilian refineries: infrastructure
Regap has a photovoltaic plant of 13,300 kW with about 20,000 solar panels, the first at a Petrobras refinery, and Petrobras plans 55.5 MW of solar capacity across its refining sites.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“Ex-proof” is shorthand for equipment carrying an explosion-protection marking (the Ex mark) that matches the area it enters. The marking states the protection concept, gas or dust group and temperature class, and it must be backed by a certificate issued by a recognised body, so a phone described as Ex-proof should come with a certificate number you can check.
The IS-04Z1 is designed to carry the marking II 2 G Ex ib IIC T4. That is a target: certification is in progress, no certificate has been issued, and SAMS will publish the certificate numbers when they exist.
In Brazilian refineries. A marking check at a hydrotreater or hydrogen unit differs from one at a product tank farm, since gas group and temperature class follow the product. Reviewers compare the label with the site's classification drawings. The IS-04Z1 marking target II 2 G Ex ib IIC T4 is not a certificate.
The route · distribution
Distributing the IS-04Z1 in Brazil Refineries
Distribution of the IS-04Z1 is by authorised partners only, and SAMS has not yet granted a territory for Brazilian refineries. Each application is reviewed on its merits. Because opening a certified Ex handset in an ordinary workshop invalidates its certificate, the partner must be able to support and service the device locally.
What SAMS looks for in a partner
- Operator relationships
- Existing supplier registrations or a clear route to them with the main operators and contractors in Brazilian refineries.
- Ex-competent staff
- People who understand zone classification, markings and the conditions of a certificate.
And equally important
- Local-language support
- Documentation, training and helpdesk in the languages the workforce uses.
- Service capability
- Spares, battery replacement and repair routed through SAMS-approved channels.
Questions · Brazil Refineries
Frequently asked questions
Can we buy an Ex-proof mobile phone 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 Ex-proof mobile phone 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.
What Ex marking will the IS-04Z1 carry?
The marking target is II 2 G Ex ib IIC T4. It becomes a marking only when the certificate is issued; until then it is a design target.
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.
How do I become a SAMS distributor for Brazilian refineries?
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 Brazilian refineries.
What zone classifications typically apply inside a refinery process unit?
Process units, pump areas, tank farms, loading racks and sample points commonly contain Zone 1 or Zone 2 gas areas, often gas group IIA or IIB with hydrogen areas in IIC. The refinery's area classification drawings are the authority, so request them before specifying handheld devices.
Which Brazilian refineries are the busiest for new project work?
Current plans point to Replan, Repar, Regap, Reduc, RPBC and Abreu e Lima, with revamps, hydroprocessing and sustainable fuels projects announced. Timelines can shift, so treat them as indicative and confirm scope and schedule with the operator or its main contractors.
Do all Brazilian refineries buy in the same way?
No. Petrobras has sold some refineries, for example RLAM in Bahia and Reman in Manaus, so procurement rules differ by owner. Purchasing is usually through registered-supplier processes. Confirm equipment approval and documentation requirements with the site operator and its HSE team.
