Czech Republic: infrastructure
The Ingolstadt-Kralupy-Litvínov pipeline can bring crude oil from Germany and can be connected to the Transalpine pipeline, so crude arrives through pipeline terminals rather than seaports.

Ex-Proof Smartphone Distributor in Czech Republic
The IS-04Z1 is an intrinsically safe Android handset designed for Zone 1 and Zone 21, built for Czech refineries, chemical plants, tank farms and coke ovens rather than for a catalogue. Gas use was 9.4 billion cubic metres in 2021 and 7.1 billion in 2023, so gas distribution and industrial gas burners remain widespread across Czech industry. Distribution partners for Czech Republic are being identified ahead of the Q4 2026 launch of the IS-04Z1.

WhereCzech Republic
Short answer. Czech Republic has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

Field notes · Czech Republic
More about Czech Republic that matters for portable equipment
Czech Republic: infrastructure
The Gazela pipeline connects Czech gas supply through Germany at Brandov or Rozvadov and through Slovakia at Lanžhot, so compressor and metering stations sit near the borders.
Czech Republic: infrastructure
In 2022 electricity production was 78.8 TWh, of which 53.6% came from fossil fuels, mostly lignite, and 40.95% from nuclear, so coal-handling plants and power stations are typical dust and gas sites.
Czech Republic: rules and approvals
ATEX equipment is split into Group I for mining and Group II for surface industries, which matters in a country with coal mining as well as refining and chemicals.
The term · Ex-proof
What “Ex-proof” means for a smartphone
“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 Czech Republic. A marking check at a Czech plant would read the certificate number, the issuing body and the complete marking string, which will be published so they can be checked. The target is II 2 G Ex ib IIC T4, with Zone 21 dust in the same programme, which matters at a fertiliser or coking site where powder and gas areas are close.
The route · distribution
Distributing the IS-04Z1 in Czech Republic
SAMS is appointing authorised distributors ahead of the Q4 2026 launch. No territory has been granted for Czech Republic 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 Czech Republic.
- 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 · Czech Republic
Frequently asked questions
Can we buy an Ex-proof smartphone in Czech Republic today?
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.
What does an Ex-proof smartphone in Czech Republic cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
What Ex marking will the IS-04Z1 carry?
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.
Which sites in Czech Republic does this cover?
The market guide for Czech Republic covers Litvínov and Záluží, Kralupy nad Vltavou, Neratovice, Valašské Meziříčí, among others. Site-level pages are linked below.
How do I become a SAMS distributor for Czech Republic?
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 Czech Republic.
Do Czech mines need different Ex equipment from refineries?
Yes. ATEX separates Group I equipment for mining from Group II for surface industries, and methane and coal dust conditions underground differ from refinery gas and vapour. Check the Group marking on any device against the area and the mine operator's own approval process.
How do pipeline terminals in the Czech Republic affect device planning?
Crude arrives by pipeline from Germany and Italy, with storage at depots such as Nelahozeves, so many classified areas are at pumping and storage sites rather than ports. Terminal operators run their own induction and device registration, so schedule approvals early for shutdown work.
Must the instructions be in Czech?
Czech law expects the instructions in Czech, so the manual, safe-use guidance and declaration of conformity are planned in Czech alongside English, with a Czech interface on Android 16. That is planned into the launch rather than translated afterwards. Certification is in progress. Check requirements with your safety officer.
