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.
Duque de Caxias: infrastructure
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.
Duque de Caxias: background
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.
The term · industrial
What “industrial” means for a smartphone
“Industrial” describes a phone built for plant conditions: sealed, drop-resistant and manageable at fleet scale through Android Enterprise. It does not by itself mean the phone may enter a classified area. Only a device with a valid explosion-protection certificate and marking may do that.
The IS-04Z1 is designed to be both an industrial Android phone (IP68, 4,000 mAh battery, 50 MP camera, Android 16 with EMM and MDM support) and an intrinsically safe one. Its explosion-protection certificates are in progress and have not been issued.
In Duque de Caxias. The refinery is in the dense Rio metropolitan area with road links to the city and airport, so contractor fleets arrive easily and MDM enrolment, spares and charging are simple to organise. Charging stays in safe areas. Large shutdown workforces will need a managed fleet, not loose devices.
The route · distribution
Distributing the IS-04Z1 in Duque de Caxias
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.
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 Duque de Caxias.
- 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 · Duque de Caxias
Frequently asked questions
Can we buy an industrial mobile phone in Duque de Caxias today?
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.
What does an industrial mobile phone in Duque de Caxias cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Is the IS-04Z1 an industrial phone as well as an Ex phone?
Yes by design: IP68 sealing, a 4,000 mAh battery, a 50 MP camera and Android 16 with EMM and MDM support. The explosion-protection certificates are separate and still in progress.
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.
