CO2 Gas System:

Carbon Dioxide (CO2) is widely used in the fire industry as an extinguishing agent for total flooding and local application fire suppression systems.

Physically the CO2 is an electrically non-conductive, odourless and colourless gas, it is heavier than air and does not leave residuals upon discharge, these properties make it a perfect choice for the fire protection of highly valuable equipment.

Carbon Dioxide is then preferred to protect hazards in normally unoccupied areas, where the presence of personnel in the protected spaces is regulated by safety devices and procedures

 The Arka Sanat’s high pressure Carbon Dioxide extinguishing systems provide protection for a variety of industrial hazards, every system is manufactured according to client specifications and may assume various configurations depending on the features that are selected standard systems are made of cylinder assemblies, valves, actuators, a
manifold and discharge nozzles.

For each system, one or more cylinders are configured as pilot cylinders and therefore they are equipped with an actuator that provides local and remote valve opening.

The rest of the cylinders are configured as slave cylinders, hence they receive a pneumatic command from the pilots to open their own valve.

All cylinders are secured to a cylinder rack that may be a wall type, self-standing open type, or a self-standing closed cabinet

 High pressure CO2 system is a specialized fire extinguishing system designed to maintain the carbon dioxide supply at 21º C and 850 psig in strength alloy steel cylinders.

The cylinders contain the CO2 required to protect the largest single hazard.

On large hazards where several cylinders are required, a manifold is used to connect each cylinder by means of flexible hoses and check valves.

Cylinder valves control the CO2 flow to the hazard through properly sized pipe, terminating in nozzles that apply the CO2.

Flow rate is controlled by nozzle orifices as well as pipe sizes.

The cylinder master valves are electronically operated and the slave valves are pressure actuated.

 Standard cylinder assembly for CO2 is equipped with a cylinder, a siphon tube and a valve. They are available in two configurations: pilot and slave. The pilot configuration comes with a solenoid valve and is used to initiate a system discharge, meanwhile the slave cylinder is actuated pneumatically upon activation of the pilot cylinder

 The cylinders can be arranged to be bracketed to a wall or to be free standing when no wall is available.

Straps for single cylinder wall mounting installations are available from Arka Sanat.

Brackets for multiple wall mounted installations and frames for multiple cylinder free standing installations are normally supplied by the installer, and assembled on site
to suit the space available Double row, free standing arrangements have the advantage (particularly for systems using main and reserve cylinders, and for joint systems), that any cylinder can be removed for recharging without disturbing the others. However, this arrangement requires two aisles and considerably more space.

The double row, wall mounting arrangement is generally used when sufficient space is not available for a free standing arrangement or for a single row wall mounting
arrangement.

For marine applications, additional cylinder supports are required. Two straps or sets of retainers must be used.
