Co2 Fire Extinguishing System Design Pdf
Want, to expedite your request? The function of dip tube is to deliver liquid carbon dioxide outside the bottle. Solenoid valve is normally in closed position. For better understanding have a look at the pressure- temperature relationship at different filling densities from the graph below.

NFPA Standard on Carbon Dioxide Extinguishing Systems
Figure below shows two time delay units, one for engine room and the other for purifier room. Now master valve is opened. See all of our publicly available Certifications and Approvals.
The time delay can be achieved in different ways. Head assembly mainly consist of a cylinder valve, which is operated by a pneumatic actuator and linkages as shown in the figure below. Therefore to safeguard against abnormally high pressures inside the bottle, a bursting disc is provided on the head assembly as shown in the figure above. This closes the pressure switch.

Fike Carbon Dioxide fire protection systems use intelligent, reliable and fast-acting control panels to quickly sense a fire before it can cause damage to property. Fixed carbon dioxide fire extinguishing systems should be kept in good working order and readily available for immediate use. Since carbon dioxide is a gas, there is no clean up associated with a system discharge. There are systems which can protect multiple spaces such as engine room and pump room together.
Head assembly consist of a pressure operated cylinder valve. Nearest coast guard can be contacted for getting assistance for the same.
Pressure gauge and pressure alarm in the mainfold. Your email address will not be published. At higher concentrations it is acutely toxic.
Only quantity of gas is different. Set pressure of relief valve is about bar. But the timer allows power supply to the solenoid only after seconds, the timing can be adjusted as required. Tell Us About Your Facility. As temperature increases, pressure also increases.
Fire Protection Systems Alarm and Detection Janus Fire Systems
This is more reliable since there is no electrical components involved. As soon as the specified time is reached, solenoid becomes energize and the solenoid valve will open. The pressure switch activates warning alarm for the leakage.
As soon as the release cabinet door is opened, a micro switch is activated. Another type of time delay unit uses an empty bottle fitted just before the head assembly. That means minimal interruption to your business. Function of the time delay unit is explained below. This field is for validation purposes and should be left unchanged.
But before engine room entry is made or space ventilated, it is recommended to obtain expert advice from shore. Click on the diagram to enlarge. Power source is always available for the unit. Leave a Reply Cancel reply Your email address will not be published.
It is an effective fire suppression agent applicable to a wide range of fire hazards. One more remote release cabinet is used, pdf snake crack which is located in a remote place such as fire control station.
