What Protronix s.r.o. does

Protronix s.r.o. is a Czech private limited company (s.r.o.) founded in 2001 and headquartered in Chrudim, Czech Republic, with 11 employees. The company specializes in custom development and manufacturing of industrial electronics, regulation, and control systems based on single-chip microcontrollers (microprocessors) sourced from manufacturers including Atmel, Microchip, Cypress, Temic, and Renesas. Its service offering spans full-cycle custom development — analysis, hardware design, embedded C/C++ software design, prototype production, testing, and certification support — alongside contract manufacturing of electronics from single pieces through medium and large batches using SMT and THT component mounting with lead-free soldering. Manufacturing capabilities include a QUADRA LASER placement machine rated at 2500-3000 components per hour, hot air reflow ovens, cabling and cable harness assembly, and CNC engraving. The company holds ISO 9001:2009 certification and products comply with EU Low Voltage Directive and EMC standards.

The company operates two distinct business lines. The first is a B2B custom development and manufacturing service targeting industrial electronics manufacturers, HVAC companies, and wellness/recreation equipment makers, with sales handled via website inquiry forms, direct phone contacts, and email. Named contacts include CEO Miloš Žáček, Head of Technical Martin Kučera, and Marketing lead Anna Žáčková. The second line is a standardized air quality sensor product portfolio — including CO2, humidity, VOC, combined, duct, and dangerous gas sensors — sold through a dedicated e-commerce storefront at cidla.cz. The company maintains a multilingual website in Czech, English, German, and Russian, indicating a regional European go-to-market posture.

The revenue model blends professional services (custom development), one-time contract manufacturing, and hardware product sales (sensors). Pricing is quote-based and not publicly disclosed. The company offers a 36-month extended warranty on products and utilizes EU development subsidies for select projects. No external investors, funding rounds, acquisitions, or parent company structure are documented; ownership is concentrated with the founding management team. The company is ISO 9001:2009 certified and positions itself as a 'pure Czech' (domestic) manufacturer with vertical integration from design through production.
