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.

Rugged 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. State operator MERO finished expanding the Transalpine pipeline at the end of 2024, delivering up to 8 million tonnes of oil a year, with the central oil depot at Nelahozeves as a key storage point. A rugged smartphone distributor in Czech Republic would carry the IS-04Z1 to these buyers once certification completes.

More about Czech Republic that matters for portable equipment
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.
Czech Republic: industry on the ground
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.
Czech Republic: industry on the ground
The country has two refineries, both owned by Česká rafinérská, including the Litvínov refinery, so Litvínov and Kralupy are the best-known flammable-liquid processing sites.
The term · rugged
What “rugged” means for a smartphone
A rugged phone is built to survive water, dust, drops and rough handling, usually rated by an IP code and a drop specification. Ruggedness is an environmental property: it says nothing about whether a phone may be used where flammable gas or dust is present. That is decided by explosion-protection certification and marking.
The IS-04Z1 combines both: an IP68 sealed rugged build and a design for Zone 1 and Zone 21 (marking target Ex ib IIC T4). The explosion-protection certificates are in progress and none has been issued.
In Czech Republic. Czech plants face cold winter rounds on tank farms and the wash-down regime of chemical plants. IP68 sealing and a rugged build, including low temperature and humidity, are designed for that. The certified ambient range is stated on the datasheet once the certificate fixes it. IP68 is not explosion protection, which comes from the ATEX certificate.
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 a rugged 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 a rugged smartphone in Czech Republic cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
How rugged is the IS-04Z1?
It is designed to IP68 sealing, with glove-friendly controls. Ruggedness is not explosion protection: that depends on the certificates, which are in progress.
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.
Are Czech refineries covered by ATEX rules for handheld devices?
The Czech Republic is an EU member, so ATEX Directive 2014/34/EU applies to equipment and employers zone workplaces under Directive 1999/92/EC. Refineries such as Litvínov typically also have internal device approval and permit-to-work procedures, so ask the HSE office before bringing phones in.
What language should Czech site documents be in?
Czech is the usual site language, and ATEX user instructions are typically expected in the local language of the destination. A Czech-language instruction sheet with the certificate pack often speeds up acceptance. Ask the operator whether it also accepts English documentation for contractors.
Why does the issuing notified body matter to Czech buyers?
FTZÚ in Ostrava-Radvanice is notified body 1026, and Czech engineers recognise it on an Ex certificate, so buyers often ask which body issued one before anything else. The certificate number, issuing body and marking string will be published for checking. No certificate exists yet, as certification is in progress.
