Repsol runs five refining and chemical complexes in Spain: Cartagena, Tarragona, Puertollano and A Coruña, plus the Petronor refinery at Muskiz beside Bilbao. This page is for the HSE, instrumentation and procurement staff at those complexes, and for the contractors who work through them, deciding what an explosion proof mobile phone in Spain has to be before it goes past a Repsol gate. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · certification programme in progress
The five complexes share a refining core but they are not alike. Cartagena sits in the Escombreras valley, sharing a harbour and a road network with a gas terminal and other industry. Tarragona is a refinery and petrochemical site inside the largest chemical cluster in southern Europe. Puertollano is the inland one, in Castilla-La Mancha, a refinery and chemical complex with no sea berth and a very different logistics pattern. A Coruña is a refinery on the Galician coast, and Petronor at Muskiz works crude and products across the Bilbao estuary. In all five the classified areas are the familiar ones: hydrocarbon vapour around process units, tank farms and loading, hydrogen in the hydrotreating and reforming units, and flammable liquid and gas in the petrochemical plants. Repsol has also announced renewable hydrogen and advanced-fuel projects at several of its Spanish sites, and every new unit arrives with its own classification drawing.
Whether a phone may be carried at all is settled by the area classification. After that, a large refinery decides how well it copes. These are the conditions that matter most across Repsol's Spanish sites.
The target marking is II 2 G Ex ib IIC T4. The IIC group is the one that covers hydrogen, so a hydrotreater and a tank farm do not need different handsets. Your instrumentation engineer will still read the temperature class against the classification drawing for each unit.
A refinery turnaround brings hundreds of people from dozens of firms through the same gate. Android Enterprise and MDM enrolment lets the site, or the lead contractor, enrol handsets, push the permit and work-pack applications and withdraw them when the stop ends.
Cartagena and Tarragona run through long hot summers with little shade on the process areas. The certificate states the ambient range, and that range is the figure to compare with the conditions the plant actually reaches in August.
Moving from a tank farm to a loading gantry can mean a long walk with no safe place to charge. The 4,000 mAh battery is specified to cover a shift, and four-constellation GNSS places a photograph on the site map instead of in a description.
Cartagena, Tarragona, A Coruña and Muskiz all sit on the coast. IP68 sealing is aimed at salt, rain and wash-down rather than at office use.
During a parada an isolation point is photographed, tagged and signed off before the line is opened. A handset that does this inside the classified area keeps the record in the same system as the permit and removes the paper that leaves the site with the crew.
An operator at Tarragona or Muskiz walks tank gauges, valve lineups and loading arms in sequence. Photographs of a seeping flange, a position fix and a call to the control room come from one device carried inside the boundary.
An inspection firm working through pipe racks and vessels at Puertollano needs drawings, a camera and a way to reach the planner. Policy set in the console limits the device to the applications the complex has approved.
Large operators normally run an internal supplier qualification and an equipment review on top of the product certificate. We have not seen Repsol's requirements for this device, so ask the procurement and HSE team at the specific complex what they need from a supplier, and ask for it before an evaluation begins.
Refineries are mainly gas and vapour areas, so Zone 1 and Zone 2 dominate. Dust zones appear where solids are handled, such as catalyst, sulphur or polymer powder. Whether any given area needs a Zone 21 designation is a decision in the explosion protection document, not something a supplier can settle.
Almost never into a classified area. Ignition source control at refinery sites is strict, and equipment normally has to be on a register before it enters. Ask the permit issuer at the complex what the rules are before planning around a personal device.
No. It describes the conditions at Repsol's published Spanish sites and what the IS-04Z1 is designed for. It is not an endorsement, a partnership or a supply agreement, and the device is pre-launch with certification in progress.
Tell us the site, the zone and gas group, and roughly how many handsets. The SAMS team replies by email with the datasheet and the certification schedule for Spain. The IS-04Z1 is pre-launch and certification is in progress, so there is no list price yet; indicative pricing is issued in writing against a stated quantity and site.
Tell us the zone, gas group and operator. We will send the datasheet and the certification schedule for your market.
