Fire Suppression / DetectionMedium

The Unitor CO2 System is a fixed total‑flood carbon dioxide fire suppression system designed to protect enclosed machinery spaces and meet SOLAS requirements. As a CO2 Fire Suppression, it is normally installed at the protected space, fire station or distributed fire-main system according to the listed extinguishing method. In that role, its primary purpose is to detect, control or extinguish fire using the approved portable or fixed firefighting arrangement. Portable extinguishers, water mist, CO2, foam, clean-agent and hose systems have different media and hazards, so operation and testing must follow the vessel fire plan. Capacity: variable. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Request a quote for this model.

Free of charge — we forward your request to qualified suppliers for Unitor (Wilhelmsen) equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
