co2-qlSEM-SAFE® by Danfoss Low-Pressure CO2 Fire Fighting System 

 

The SEM-SAFE® low-pressure COsystems from Danfoss are intended for use where large machinery and cargo spaces require protection with carbon dioxide. The advantage of the low-pressure system is that one single tank replaces a large number of CO2 cylinders with an approximate saving of 50% in weight. The tank, main valves, distribution valves, refrigerators, and associated controls are supplied prewired and ready assembled on a common steel frame.

The quantity of carbon dioxide is shown directly by an electronic gauge indicating the actual tons of CO2 in the tank. The gauge unit is fitted with alarm contacts for warning at low CO2 contents in the tank. Recharging after use is made directly from a truck.
For large vessels the installation cost of a SEM-SAFE® low-pressure CO2 system is considerably lower compared to the installation costs of a high-pressure CO2 system. The system is designed to meet the requirements of the appropriate classification societies to which the vessel is being built.

Tank

The tank is constructed as a steel pressure vessel in accordance with the classification society requirements. The tank is equipped with two safety valves, which are fitted to a three way  hangeover valve, thus one safety valve is connected to the vessel if the other one is out of operation. The tank unit is supplied complete and ready for use, installed on a rectangular steel framework and held in position by thermally insulated supports. The tank is insulated with non-flammable polyurethane foam protected by an aluminium cover.
