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 explains what to look for in an ATEX and IECEx cell phone for Sweden, and where the IS-04Z1 stands against that list today.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for Sweden: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
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. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

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 classified areas, operators and sites below are the ones covered in the SAMS Sweden market guide.
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.
ATEX is the European legal framework for equipment used in explosive atmospheres (Directive 2014/34/EU). IECEx is the international certification scheme built on the IEC 60079 standards. Buyers outside Europe often ask for both: an IECEx certificate is the technical evidence most national regimes build on, while ATEX is the legal route into the European market.
For the IS-04Z1 both routes are in progress with TÜV in Germany and neither certificate has been issued. The marking target is II 2 G Ex ib IIC T4: equipment Group II (surface industry), Category 2 (Zone 1 gas), protection concept ib (intrinsic safety), gas group IIC and temperature class T4.
In Sweden. A Swedish procurement or HSE reviewer at Preem, Borealis or the pulp mills would expect ATEX evidence under the EU framework, with ambient range given particular attention. A dual ATEX and IECEx route helps international contractors and EPCs working at Stenungsund or the northern steel and mining sites. No certificate has been issued for the IS-04Z1.
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
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.
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.
Not yet. Both routes are in progress with TÜV in Germany and no certificate has been issued. Any listing that says otherwise is wrong.
The market guide for Sweden covers Lysekil, Gothenburg river bank, Stenungsund, Nynäshamn, among others. Site-level pages are linked below.
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
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.
