CEMarked CEMarked Precision-manufactured power distribution, voltage regulation, and hazardous-area assemblies designed for strict continuous operations across Slovak industrial clusters.
Industrial infrastructure across Slovakia—from Bratislava’s automotive manufacturing corridors to the heavy chemical complexes of Košice and chemical processing in Šaľa—demands uncompromising explosion-proof switchgear that bridges European Directives with real-world operating longevity.
Slovakia enforces strict adherence to EU ATEX workplace legislation (Directive 1999/92/EC) through national transpositions. Our control panels strictly align with EN IEC 60079-0 (General Requirements), EN IEC 60079-1 (Flameproof Enclosures 'd'), and EN IEC 60079-7 (Increased Safety 'e'). Whether deployed in gas Zone 1/2 or combustible dust Zone 21/22, our assemblies withstand internal explosions without propagating flames to surrounding atmospheres.
Operating in Slovak continental weather involves winter drops down to -30°C. At cryogenic thresholds, ordinary flameproof flange joints experience micro-gapping, and synthetic seals turn brittle. We employ certified silicone sealing profiles, precision CNC-machined flame paths, low-temperature graded ductile iron or 316L stainless steel, and integrated internal anticondensation space heaters paired with ambient-sensing thermostats.
Driven by high-power drives and modern PLC/SCADA installations, electrical installations must eliminate harmonic cross-talk. Our hazardous-area panels integrate specialized DC smoothing reactors, high-efficiency isolation transformers, and RFI/EMC line suppression filters to ensure compliance with EN 61000-6-2/4, safeguarding digital communications across Slovak smart manufacturing facilities.
Our engineering capabilities cater to mission-critical applications across the main pillars of the Slovak Republic’s economy.
Bratislava, Trnava, and Žilina represent automotive innovation hubs. Solvents and volatile organic compounds (VOCs) create persistent Zone 1 and Zone 2 hazardous ambients. We supply Ex d/Ex de custom variable speed drive (VFD) panels, conveyor control stations, and ventilation monitoring enclosures engineered to resist aggressive paint solvents while maintaining IP66 ingress protection.
The Slovnaft refinery complex in Bratislava and surrounding chemical plants require heavy-duty flameproof power distribution switchboards and Motor Control Centers (MCC). We engineer pressurized (Ex p) and explosion-proof (Ex d) systems featuring gas group IIC certification, handling corrosive ambient H2S atmospheres and rigorous continuous loads.
Facilities like Duslo Šaľa generate fine, conductive, and combustible chemical powders. These require certified Ex tb/tc (dust ignition protection) combined with explosion-proof control apparatus. Our sealed electrical enclosures prevent hot internal components or arcing switch contacts from igniting ambient dust clouds during routine cycling.
Slovakia’s high-capacity pipeline transit routes and underground natural gas reservoirs (such as the Láb storage complex) mandate autonomous, remote-operable Ex d RTU (Remote Terminal Unit) panels and valve actuator controllers functioning under extreme outdoor conditions without maintenance intervention.
As Slovak industries implement the European Green Deal and embrace Industry 4.0 automation, equipment requirements for hazardous zones are experiencing a rapid structural shift.
Slovak plant operators increasingly favor hybrid solutions: robust Ex d flameproof enclosures housing high-power circuit breakers and inverters, combined with intrinsically safe (Ex i) terminal chambers. This allows process engineers to service field sensors and fieldbus communication links without executing full plant de-energization or obtaining hot-work permits.
With national decarbonization initiatives driving green hydrogen pilot plants alongside existing pipeline infrastructure, hazardous area ratings must upgrade from Group IIA/IIB to Group IIC (Hydrogen). Our research and engineering team fabricates specialized flamepath geometries designed to contain the ultra-high explosion pressures and low maximum experimental safe gaps (MESG) typical of hydrogen combustion.
Predictive maintenance is becoming standard across Central European manufacturing. Modern Slovak projects require flameproof control panels pre-integrated with intelligent thermal sensors, vibration analysis modules, and fiber-optic communication nodes that safely transmit critical asset health data out of Zone 1 zones into central cloud SCADA networks.

Decades of industrial power design experience underpin every unit that leaves our modern manufacturing facilities.
Backed by our group’s foundation in building PC, PLC, and SCADA-based control panels since 1990—specifically engineered for hazardous locations—we know that magnetics and enclosures must fit together seamlessly. We engineer every panel for optimal inrush capacity, clean terminations, compact footprints, and field-ready modularity.
Operating from our plant in Santej, Ahmedabad, we manage an end-to-end production flow. From winding, assembly, and metal enclosure fabrication to casting and computerized validation, our facilities support transformers from 50VA to 5000kVA, line and load reactors up to 2500A, and harmonic filtering up to 500HP for over 45 major industrial OEMs globally.
Every assembly is validated using automated test beds: computerized open-circuit and short-circuit testing panels, insulation resistance testing (Megger), Double Voltage Double Frequency (DVDF) induced overvoltage testing, milli-ohm winding resistance diagnostics, infrared thermal rise checks, and certified hydraulic pressure tests for explosion-proof vessels.
