Danfoss Semco CO2 systems meet a number of international class requirements, including LRS, DNV, BV, PRS, CCS, ABS, GL, RMRS and NK, as well as national authorities. CONSTRUCTION. he Danfoss Semco CO2 system consists of one or more pressure cylinders containing the extinguishing agent CO2. he cylinders are connected via a common manifold. From the main manifold, the extinguishing agent is led through distribution valves to the protected spaces. he valve construction, cylinder size, and cylinder pressure, combined with the computer calculated pipe and nozzle dimensioning, ensures that the extinguishing agent is distributed in correct quantities and within the prescribed time. he release is activated pneumatically, electrically and/or mechanically. Danfoss Semco pressure-operated cylinder valves ofer the possibility of connecting CO2 cylinders in groups operated pneumatically from one or more release cabinets equipped with CO2 gas cylinders. he release cabinets are equipped with pilot valves for use in opening cylinders and distribution valves by pipe connections. For pneumatic operation, the built-in actuator is used for each cylinder valve. hese are connected to the other cylinder valves in the group via series-connected, lexible high-pressure hoses.

CO 2 CYLINDERS. he cylinders are delivered as 67.5-litre steel cylinders illed with 45 kg of CO2, or alternatively as 80-litre steel cylinders illed with 53.6 kg of CO2. To enable remote control and quick release, the c ylinders are supplied with Danfoss Semco pressure operated quick opening valves, which also ofer the possibility of manual operation. he valve construction secures against damaging overpressure in the cylinder, as the valve has a built-in bursting disc, activated at a nominal pressure of 190 bar. CO 2 ROOM. he cylinders are normally stored in a separate, well-ventilated and insulated room, where the temperature is kept between 0° and 40°C. he room must have free access to open air. he room should have a minimum clear height of 2.4 m to provide adequate space for the mounting of manifolds and weighing beams for check weighing of the cylinders. CHECKING EQUIPMENT. he cylinders can be checked by a weighing device or liquid level measurement. SPECIAL EQUIPMENT. To reduce the installation time in CO2 rooms onboard ships, cylinder arrangements mounted in racks consisting of up to 100 pieces of 45/53.6 kg cylinders, complete with manifold and ixing equipment, can be supplied.

C O 2 E xti ng uishing System: Rel e a s e System THE PRESSURE CONTROLLED CYLINDER VALVE. All Danfoss Semco’s release systems are based on the unique pressure operated cylinder valve. his valve is used in all systems in which pressure cylinders (CO2 and N2) form a part. CO2 cylinders, with contents of up to 60 kg discharge, can be released within one minute. Valve housings and internal parts are made of brass or stainless steel, with tightening materials of neoprene or copper. he valve is constructed as a combined pressure operated quick opening valve with hand wheel for manual opening. he Danfoss Semco valve is designed with a unique function that enables the user to perform a real check of the valve function. By opening the control valve for releasing the cylinders while leaving the distribution valve closed, the manifold will be pressurised. It can then be proved that each valve is opened. By closing the control valve, the release piping system will be relieved and the cylinder valves will close. his function is required by some classes and authorities. PNEUMATIC RELEASE SYSTEM.Total looding systems require groups of cylinders to be released simultaneously. For this purpose, pneumatically operated cylinder valves are used in conjunction with the pilot pressure from the master release box containing control cylinder(s) (CO2 or N2), two control valves, a pressure gauge, and one or two door switches. As an option, the system can be supplied with a pneumatic time delay device to delay the opening of the main valve. Emergency release from the CO2 room can be made by manually opening the cylinder valve and then operating the two local control valves.
