◆Introduction:
FK-5-1-12 suppression agent is the most eco-friendly chemical clean agent available.
What is the Best Cleaner Fire Suppression System?
Several factors should be considered when evaluating which cleaning agent system to implement. You must consider the area or type of equipment to be protected, the amount of space required for the cleaner cylinder, and the location of the cylinder relative to the protected area or asset. As mentioned earlier, inert gases are less efficient and require more reagents than chemical reagents, so larger or more cylinders are required to protect the same space. Since the pressure of each cylinder and the inert gas flow more easily through the discharge line, the inert gas system can be located away from the protected space. The FK5112 fluid system needs to be closer to the protected area because the compressed liquid does not flow like an inert gas, so the distance between the cylinder and the discharge line needs to be shorter.
