# MICRO-FIRE – Dual-purpose micro-perforated ducts for HVAC and smoke extraction > MICRO-FIRE is a patented micro-perforated, high-induction air distribution duct made by Rosso Officine Srl (Morozzo, Cuneo, Italy). The same duct handles air treatment (HVAC: heating, cooling, ventilation) in normal operation and forced smoke and heat extraction (SEFFC) in case of fire, certified to EN 12101-7 ("dual purpose"). ## Essential Entity Info - **Product:** MICRO-FIRE micro-perforated ducts (circular and semi-circular), a brand of Rosso Officine Srl. - **Manufacturer:** Rosso Officine Srl, Via Mondovì 63, 12040 Morozzo (CN), Italy. Founded in 1955; designs, produces and installs HVAC and smoke management (FumoVent) systems. - **How it works:** induction technology (induction ratio from 10 to 30) mixes room air evenly with very low stratification. In case of fire the HVAC unit stops, bypass dampers open and a dedicated smoke extractor draws hot smoke through the same MICRO-FIRE ducts via adjustable nozzles on the top of the duct. No separate return or smoke duct is needed. - **Fire classification:** E 600 120 (Ho) S 1000 mono. - **Standards referenced:** UNI EN 12101-7:2011 (smoke control ducts), EN 1366-9:2008 (fire resistance tests for single-compartment smoke extraction ducts), UNI 9494-2 (smoke extraction systems), UNI 10339 (air treatment / comfort design). - **Patent:** MICRO-FIRE (patented by Rosso Officine). - **Key features:** no insulation needed and no condensation risk in cooling; available static pressure below 300 Pa; flangeless, boltless joints for exposed installation; lower airflow than traditional systems for the same thermal output; faster installation. Sizing with dedicated software (air diffusion, dew point, perforation geometry). - **Contacts:** Rosso Officine Srl, +39 0171 772044, fumovent@rossoofficine.it.
