Model WJFE 300 MODULAR


Produced by: CRISTANINI - ITALY



A fire that develops inside any infrastructure (whether fixed or mobile platforms) requires a delicate and dangerous intervention, not only for the operator, but also for the safety of the infrastructure.

The WJFE 300 High Pressure System makes such a situation considerably less dangerous, by allowing the operator to rapidly operate from the outside of the place where the fire developed.

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. 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.
