BorsodChem's Kazincbarcika complex produces MDI, TDI and PVC at industrial scale, while Budapest is home to two of Hungary's major pharmaceutical manufacturers, Richter Gedeon and Egis, both working with solvents in active ingredient production. This page is for the HSE, maintenance and engineering teams at those plants who need to know what an explosion proof mobile phone for Hungary has to offer, and what it cannot yet claim: the IS-04Z1 is designed for Zone 1 and Zone 21, and certification is in progress. The IS-04Z1 is designed around intrinsic safety rather than a flameproof enclosure.
Launching Q4 2026 · ATEX programme in progress
Kazincbarcika, in Borsod county, is the main production site of BorsodChem, a producer of isocyanates (MDI and TDI), PVC and chlor-alkali products. Process chemistry there runs from chlorine and hydrogen through nitration and aniline-type intermediates to polymer powder, so the plant carries gas, vapour and dust hazards side by side. The pharmaceutical picture is different in kind: Richter Gedeon works in Budapest and Dorog, Egis in Budapest and Körmend, and active ingredient synthesis there depends on organic solvents that are charged, distilled, recovered and stored. The classified areas are smaller than a refinery's but more numerous and more varied.
A BorsodChem PVC bagging hall and a Richter or Egis powder suite are dust areas; the reactors beside them are gas areas. The IS-04Z1 design target covers Zone 1 and Zone 21, so a technician does not swap equipment to cross the boundary.
Chlor-alkali hydrogen is IIC, while most plant solvents are IIA or IIB. The marking target is II 2 G Ex ib IIC T4, so the group does not limit where the unit can go, but the temperature class should be checked against solvents with low autoignition temperatures such as carbon disulphide.
Chlorine, phosgene-type chemistry and isocyanates are toxic before they are flammable. A handset does not replace a personal gas detector or the plant's toxic-gas alarms; it sits alongside them for calls, photographs and permits.
Pharmaceutical areas are washed down and cleaned to procedure. IP68 sealing is designed to tolerate wiping and washdown, though a cleaning agent should always be checked against the housing material with SAMS before it enters a validated cleaning procedure.
A 50 MP camera and four-constellation GNSS record a defect, a tag and a position. In regulated pharmaceutical work, how records are held and signed is set by the operator's own quality system, and the handset is managed from the existing MDM console.
Operators on the isocyanate and PVC units walk long routes between reactors, compressors and dryers. A handset that logs readings, photographs a leak and calls the control room replaces a radio and a clipboard, and reduces trips back to a safe area.
A fitter changing a pump seal or a valve on a solvent line works under a permit and often inside a Zone 1 or Zone 2 room. The handset opens the work order, records the isolation and photographs the finished job without leaving the classified space.
Contractor crews on a plant change work arrive with their own paperwork. Android Enterprise policy lets the operator issue enrolled devices for the task, restrict them to approved applications and wipe them when the crew leaves.
Continuous chemical plants such as Kazincbarcika run through planned shutdowns, when contractor numbers rise and device control becomes a daily task. Pharmaceutical sites work differently: production runs in campaigns and batches, with scheduled maintenance between them, and changes to equipment are controlled through the operator's quality system. We have not verified any named supplier-registration scheme for either BorsodChem, Richter Gedeon or Egis, so none is described here. Ask each company's procurement, HSE and quality teams for their approval route, the documents they need and any site induction. Expect questions on the ATEX certificate and marking, Hungarian-language instructions, temperature class, cleaning compatibility and how repairs are controlled.
No. The device is pre-launch and certification, including ATEX, is still in progress ahead of the Q4 2026 launch. Until the certificate exists, no unit should enter a classified area.
No. Each operator runs its own procurement, HSE and quality review, even where two sites are in the same city, so each decision stands alone.
The Ex marking addresses ignition, not toxicity. Toxic-gas detection and respiratory protection remain separate controls, and the handset is not a substitute for either.
That depends on the cleanroom grade and the operator's procedures. The IS-04Z1 is designed for classified areas rather than for controlled-environment suites, so confirm surface, cleaning and entry rules with the site's quality team before planning use.
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 Hungary. 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.
