Hazardous Area Mobile Phone Distributor in Duque de Caxias
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. It hosts the Petrobras Duque de Caxias refinery (Reduc), which started up in 1961, so refining and gas-processing units create Zone 1 areas. A hazardous area mobile phone distributor in Duque de Caxias would carry the IS-04Z1 to these buyers once certification completes.

Duque de Caxias: industry on the ground
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.
Duque de Caxias: geography and layout
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.
Duque de Caxias: projects and investment
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.
Duque de Caxias: industry on the ground
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.
The term · hazardous area
What “hazardous area” means for a smartphone
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In Duque de Caxias. Reduc has refinery process units, tank farms and pipelines, loading and dispatch areas, and biofuel (SAF and renewable diesel) processing, with Petrobras as operator. Petrobras classifies the areas; SAMS does not. A multi-product site means more than one product and classification may sit side by side.

Questions · Duque de Caxias
Frequently asked questions
Can we buy a hazardous area mobile phone in Duque de Caxias today?
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.
What does a hazardous area mobile phone in Duque de Caxias 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.
Which hazardous areas is the IS-04Z1 designed for?
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
Which areas at Duque de Caxias would use it?
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.
How do I become a SAMS distributor for Duque de Caxias?
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.
How should I plan devices for a Rio de Janeiro refinery visit?
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.
What does the refinery's lubricant and gas role mean for hazard types?
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.
Will the 2026 shutdowns affect when I should order?
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.
