The SEM-SAFE® low-pressure CO2 systems are intended for use where large machinery spaces and cargo spaces require fire protection with carbon dioxide. The advantage of the SEM-SAFE® low-pressure CO2 system is that one single tanke 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 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.
