Fire Fighting
We inspect, service, test and repair all manufacturers and classifications of fire extinguishers and are also equipped to meet your entire exit and egress lighting needs. Our Team is capable to work in different Fire Extinguishers Systems:
· Powder extinguishing systems
· Foam extinguishing systems
· Gas extinguishing systems
· Water extinguishing systems
· Wet-Pipe Systems
· Anti-freeze Systems
· Dry-Pipe Systems
· Pre-action Systems
· Deluge Systems
Water extinguishing Systems
Water is mainly used for fighting fire classification A fires (glowing substances).The extinguishing effect of water is mainly based on its heat binding capability. The cooling effect of water disturbs the prerequisites of a thermal reaction and hinders further processing of inflammable substances, so that the formation of inflammable gases and vapors is interrupted. Thus, water extinguishes by cooling.
Ex : Deluge System, is of high pressure type system and consists mainly of the spray cages with their high velocity nozzles, the pneum. actuator system, the deluge valve sets and the water pressure tank.
Foam extinguishing system
Extinguishing foam is a highly effective mixture of water, foaming agent and air. The air foam utilizes different extinguishing effects: cooling, suffocating, separating, covering, restraining and displacing - each one alone or together with others they provide a quick extinguishing success. Film forming foam compounds were developed for fighting fire classification A and B fires. In fire classification A high extinguishing efficiency is achieved with the combination of the cooling effect of water and a high net effect of the AFFF part. In case of liquid fires a very thin sliding film is formed on the burning liquid, which gives the foam excellent flow properties and protects the combustion area from further oxygen supply.
Gas extinguishing systems
The extinguishing effect of argon, nitrogen and carbon dioxide is achieved by displacing atmospheric oxygen. This is called the suffocation effect, which occurs if the value necessary for combustion falls below the specific limit value.
Powder extinguishing system
Extinguishing powders are highly effective and fast extinguish ants. The sudden extinguishing effect of the powder cloud is caused by the suffocation effect and the, so called, autocatalytic effect, a chemical intervention into the combustion process. The formation of melting layers on glowing incendiary matters prevents the diffusion of atmospheric oxygen and the heat-up of immediate fire surroundings. Re-inflammations are not possible. Extinguishing powders mainly consist of non-poisonous inorganic salts mixed with waterproofing and pouring agents.
