The WJFE300 allows:
1. the opening of a small hole in fire stop or stainless steel walls by means of a special lance with a high pressure water jet and abrasive mix.
2. With the same lance, after the opening, the introduction in a room where the fire has developed of a fine mist water of high efficacy.
The water drops of the mist have a Ø of approx 10-20 μ (0,0003937 in – 0,0007874 in). This allows an extremely high surface of thermal exchange, thus lowering the temperature quickly.
This system highly reduces the damage that, normally, is created using useless large volumes of water.
