Indirect carbon dioxide tube fire detecting systems, are automatic gaseous fire suppression systems, that use carbon dioxide as the fire extinguishing agent, this system is easy and simple to construct and easy to install.
The best advantage is that the carbon dioxide fire-detecting tube does not require any outer power supply and can work stand-alone, also with functions of fire detection, fire alarm, and fire suppression.
This fire prevention system, it is divided into direct or indirect types, The extinguishing agent normally is carbon dioxide or hfc-227ea, hereby we recommend the indirect type carbon dioxide fire detecting tube system.
