SF50A-1, SF50B-1 - frost proof down to -30 °C
The innovative design of these devices combines all the features that can be found on modern extinguishing devices of this type. Namely, maximum functional benefit, simple service and low maintenance costs. The container and chassis form two separate units. In this way, welded connections on the pressure vessel are reduced to the bare minimum and any repair work is considerably simplified. The large base frame of the chassis serves as a ram protection for the container and as a carrying aid for transport over stairs and landings.
The extinguishing agent container is made of stainless steel and offers the best possible corrosion protection and a considerably longer service life than extinguishing agent containers with an interior coating. The adjusted pressure regulation guarantees a constant jet of extinguishing agent from the beginning to the end of the extinguishing.
Frost protected foam
The fire extinguishing agent foam is created from a water / foam agent mixture by adding air. In the case of fires involving solid substances (fire class A), the high network effect combined with the interruption of gas exchange and the cooling effect result in the excellent extinguishing properties.
Foam extinguishing agents work by covering the entire surface of flammable liquids with a vapor-tight foam blanket, which prevents the access of oxygen (sticking effect) and cools the surface (cooling effect).
Features
Fire class A, combustible solid materials
such as wood, car tires, textiles
Fire class B, flammable liquids
such as petrol, paint, oil
Electrical systems
SF50A-1 can be used up to 1.000 V, minimum distance 1 meter;
SF50B-1 use only in voltage-free systems.
Areas of application
Production and storage areas at risk of frost. If there is a high risk of fire or if there is a risk of fire spreading rapidly.
