The Unitor CO₂ system is a total flooding system designed to suppress fires in machinery spaces of Category A, engine rooms, pump rooms and cargo holds. It has been supplied to hundreds of vessels and offshore installations worldwide.
- Options of manual or pressure operated cylinder top valves to quickly discharge the CO2 gas
- No requirement for electrical power, water or machinery to release the gas
- The system is equipped with alarm devices which will pre-warn the crew to evacuate the protected space
- A safe release delay function to ensure the safety of the crew
- Sequential release design provides optimised protection to the enclosed space
A cost effective solution
Designed for optimal system performance, keeping both installation and operational costs low:
- The system is available on rack modules to save installation time and cost
- Quick discharge reduces potential cost of damages
- Minimal and easy maintenance keeps operational costs low
The Unitor CO2 system can be complemented by the Unitor XFlow Local Application fire fighting system to provide total fire protection for engine rooms. Further, local systems for paint lockers and galley ducting are available, and smoke sampling systems for cargo holds can be incorporated in the CO2 system package.
Where can the system be used?
- Machinery spaces
- Cargo spaces including spaces for dangerous goods
- Two stroke main engines scavenge boxes
- Paint lockers and other flammable liquid lockers
- Galley exhaust duct
Tankers (oil and chemical)
The Unitor CO2 system consists of a high pressure cylinder bank with either manual or pressure operated cylinder top valves. The pressure operated valves are connected to manifolds using flexible, high pressure hoses. The cylinder bank, manifold and distribution valves are stored in a well-ventilated and insulated room.
From the main distribution valves, a piping system is used to distribute the gas to the discharge nozzles which are placed uniformly throughout the protected spaces. The top valves can be operated both pneumatically and manually.
Activation of the system
When releasing the system from the release cabinet, pilot gas immediately opens the distribution valves.
After a pre-set time delay, the cylinder valves open. When the cylinder valves open, the CO2 gas is discharged through the piping and nozzles into the protected space.
Rules and regulations for CO2 systems
The Unitor CO2 system is designed in accordance to SOLAS and IMO MODU Code. In addition, it is approved by all major classification societies. SOLAS, Chapter II-2, Part C, Reg. 10 FSS Code, Chapter 5 IBC Code IGC Code Classification societies rules and regulations Authorities rules and regulations Other standards (EN, ISO, DOT, etc)
The Unitor XFlow® water mist system gives you the opportunity to integrate local and full fire protection in a single system. The solution can be applied as a total flooding system, local application fire fighting system and for accommodation areas.
The Unitor Inergen® system is a fire extinguishing solution for enclosed spaces. Inergen® is a clean agent consisting of only atmospheric gases and can be applied on merchant marine and offshore structures.
The Unitor 1230 system has been industralised and adjusted for the offshore and maritime industry based on the Novec 1230 system. It is designed as a total flooding system for machinery spaces, pump rooms, compressor rooms and control rooms. The solution is particulary suited for rooms with sensitive equipment and vessels where space is limited.
The Unitor high expansion foam fire extinguishing system (Unitor high foam system) uses foam consisting of a synthetic foam concentrate, water and air, which is highly effective for machinery space applications. The system is designed as total flooding system for machinery spaces of Category A, cargo pump rooms and other enclosed spaces onboard vessels and offshore installations.
