What Siber does
Siber (commercial brand: Siberzone) is a Barcelona-headquartered Spanish manufacturer of controlled mechanical ventilation (VMC — Ventilación Mecánica Controlada) systems for residential and tertiary applications. The company claims to be the first manufacturer of a complete ventilation system in Spain and operates under the Zehnder Group umbrella, a global indoor climate management leader. Its product portfolio centers on three core unit families — EVO (double-flow with heat recovery), ECO (hygro-regulating single-flow), and ONE (controlled-mechanical ventilation) — supplemented by specialized units including SIBERVENT MONOFÁSICO M402 III, HIGROVENT COMPACTA, INSUFLAIR HOME, VMC A4 II, and SIBER DF AIR 2.
The company addresses indoor air quality, humidity control, energy efficiency, radon gas mitigation, and regulatory compliance under Spanish building codes (CTE HS3, RITE 2007). Technical suitability is documented via the DIT 597R/23 certificate from the Instituto de Ciencias de la Construcción Eduardo Torroja. Siber supports specification by architects and developers through BIM-involved design tools, technical documentation, and the Siber Academy online training platform, and positions its products as compatible with Passivhaus, BREEAM, and WELL sustainability frameworks.
Siber operates a hybrid go-to-market: a direct-to-customer online store (Tienda) for hardware and accessories, paired with a national network of certified installers, authorized distributors, and zero-consumption distributors. Revenue is generated through hardware sales (VMC units, filters, ventilation networks), professional services (diagnosis and certification, installation support, commissioning, post-sale SAT technical support, Premium maintenance plans, warranty extensions), and recurring training revenue from the Siber Academy. Pricing is quote-based rather than publicly disclosed. Customer segments span single-family residential, multi-family residential, building rehabilitation, tertiary/commercial, garage ventilation, and radon gas — primarily serving Spanish SMB and mid-market projects, with a small hospitality and social-housing tail.
