Sweden: projects and investment
Preem has announced plans, still in progress, to expand its refinery at Lysekil, which indicates continuing construction and maintenance work on the west coast.
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for refinery and cracker rounds on the west coast, mill and recovery boiler areas inland, and winter shifts in the north where a device is handled through two layers of glove. This page sets out how an Ex-proof mobile phone supply route to Sweden will work for the IS-04Z1, and what is and is not available before launch.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. An Ex-proof mobile phone for Sweden cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.
| Check | What to look for | IS-04Z1 today |

| Ex marking | Group, category, protection concept, gas group, temperature class | II 2 G Ex ib IIC T4 (target) |
| Gas group | IIA, IIB or IIC matched to the area drawing | IIC (target) |

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in Sweden. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
The main operators, industrial areas and sites that the SAMS Sweden market guide covers.
Preem has announced plans, still in progress, to expand its refinery at Lysekil, which indicates continuing construction and maintenance work on the west coast.
In 2023, 98% of Swedish electricity generation came from renewables and nuclear, and over 20% of generation was exported to the rest of Europe, so hydro and nuclear sites dominate electricity work.
Sweden had the EU's highest share of renewable energy for heating and cooling at 69% in 2022, so biomass boilers and district heating plants with combustible dust are common.
Preem sells fuels, heating oil and lubricating oils to companies and individuals in Sweden and Norway, and since 2026 its parent company has been part of VARO Energy, so site procedures may follow the new group.
“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 Sweden. A Swedish marking check reads II 2 G Ex ib IIC T4 for the refinery and cracker areas, with the hydrogen projects at the steelmakers in mind. In the mill sector, wood dust is a primary hazard, so Zone 21 evidence is read as closely as the gas marking, and the lower limit of the ambient range is checked.
Nothing can be bought for Sweden today: the IS-04Z1 is pre-launch, and SAMS will supply end users through authorised distributors once certificates exist. What a buyer can do now is take the specification, ask for the written certification schedule and arrange a safe-area evaluation, so that the right local channel contacts you at launch.
The technical specification, marking target and conditions of use, sent by email.
Which certificates are in progress, in what order, and what is still to be confirmed.
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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.
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
The market guide for Sweden covers Lysekil, Gothenburg river bank, Stenungsund, Nynäshamn, among others. Site-level pages are linked below.
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Sweden is an EU member, so ATEX Directive 2014/34/EU applies to equipment and Directive 1999/92/EC to zoning. Zone 1 and Zone 2 devices should carry CE and Ex markings. Refineries such as Lysekil typically add their own permit and device registration rules, so ask the HSE office.
Swedish is the working language but English is widely used at international industrial sites. ATEX instructions are typically expected in the language of the destination country, so confirm with the operator whether Swedish documents are needed. Bring the declaration of conformity and certificate.
A rugged build covers low temperature and thermal shock, but the certified ambient range is a certificate parameter, published with the datasheet. Certification is in progress. Check the lower limit against the coldest conditions at the mine or steelworks before specifying.
