Enagás owns Spain's gas transmission network and the regasification plants at Barcelona, Cartagena and Huelva, and holds interests in the Bilbao and Sagunto terminals. This page is for the HSE, operations and telecoms staff at those plants and along the pipeline network who need an explosion proof mobile phone in Spain that works from the jetty to a compressor hall. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.

Enagás is a different kind of operator from a refiner. Its hazardous areas are mostly methane, which is gas group IIA and relatively hard to ignite, spread across a national network instead of a single site. Three of its terminals are wholly owned, at Barcelona, Cartagena and Huelva, and it also holds the El Musel plant at Gijón and interests in the BBG terminal in Bilbao and the Saggas terminal at Sagunto. Between the terminals sit compression stations, pressure regulating and metering stations, and three underground storage facilities: Serrablo in Huesca, Yela in Guadalajara and Gaviota, an offshore field off the Bizkaia coast. Enagás also acts as technical system manager for the Spanish gas system. At a terminal the busy classified areas are the ship berth, the cryogenic tanks, the vaporisers and the send-out lines. Many open-air gas areas are Zone 2, with Zone 1 where a release is expected in normal operation, such as vents and sampling points.
A gas transmission operator spends its time between sites, so the handset has to be useful at a terminal, on a pipeline route and in a car. The conditions below shape that.
Methane is IIA, but odorant systems, nitrogen and sampling lines each have their own considerations. The IS-04Z1 is targeted at II 2 G Ex ib IIC T4, which covers the gas groups an operator is likely to meet. The temperature class still has to be read against each classification drawing.
Metering and regulating stations are often visited by one person, a long way from help. Four-constellation GNSS gives a position that can be shared with the control centre, and the 4G and Wi-Fi radios keep the call link up where coverage allows.
A carrier arrives to a schedule, and the people on the jetty, in the tank area and in the control building are all in contact for the duration. One device that works across those boundaries removes a swap each time.
Barcelona, Cartagena, Huelva, Gijón and the Bizkaia coast are all marine environments. IP68 sealing is meant for that rather than for an office.
During a ship discharge an operator walks the berth, the arms and the tank area. Readings, photographs and a call to the control room come from one device carried inside the classified area.
A technician at a compression station moves between a turbine hall and an outdoor skid. A managed handset carries the maintenance instructions and records the visit, and the camera can be controlled by site policy.
Wellhead and surface plant work at a storage site follows a planned programme with contractors. Enrolled handsets let the site manage which applications are available during the job.
Equipment suitable for Zone 1 may be used in Zone 2, so one handset covers both. Operators often prefer to issue a single device for the whole site rather than map each pocket of Zone 1 to a different phone.
Operators of this size normally run supplier qualification and technical review, and some publish tender conditions. We have not verified a specific Enagás route for handsets, so ask Enagás procurement and the plant's HSE team what they require.
It is an offshore installation, so access, transport and communications are planned for a specific set of conditions. The IS-04Z1 has not been tested for it and nothing on this page claims that it has. Any offshore trial would need its own approvals.
No. It is a communications and data device. Personal gas detection is a separate piece of equipment and a handset does not substitute for it.
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.
