Gas Extinguishing Systems |
||
Our fire extinguishing systems protect against fire and flames quickly and reliably. But using water, foam or powder extinguishing systems is not permissible when highly sensitive systems and areas have to be protected. The negative impact of the extinguishing agent on the protected objects is too great. |
||
Gases that displace oxygen |
||
Carbon dioxide: The most common of all quenching gases, it displaces atmospheric oxygen from the fire area and thereby smothers the flames quickly and reliably. CO2 is available quickly at competitive prices. Next to the high-pressure version that is frequently found, where CO2 is stored in one or several cylinders (up to 50 kg), a low-pressure CO2 system is suitable for larger protected objects. It consists of just a single container with space for several tons of carbon dioxide. |
||
Argon: As an inert gas of the 8th main group, argon has all of the properties required to lower the atmospheric oxygen level in the fire area and reliably smother the flames. In contrast to CO2, there is no risk of argon breaking down at elevated temperatures. This makes argon suitable even for use with extreme combustion processes, e.g. metal fires. |
||
Nitrogen: As the main component of air, nitrogen is neither toxic nor harmful to the environment. The atmospheric oxygen is lowered by releasing the quenching gas stored in pressurised cylinders into the protection zone, smothering the fire. Nitrogen is also used frequently for inerting process sections. Here the air within the system is enriched with nitrogen so that the risk of fire is excluded from the outset. |
||
Quenching gases with a chemical effect |
||
NOVEC1230® and FM200®: The extinguishing action of the NOVEC1230® and FM200® quenching gases is based on intervention in the combustion process. Compared to an inert gas fire extinguishing system that smothers the flames, the required extinguishing agent concentration is much lower for the same level of protection. Especially for larger protected objects, the space required for the extinguishing agent container is therefore significantly reduced. NOVEC1230® and FM200® are very popular thanks to their outstanding extinguishing action and low impact on the environment. |
