Most vehicle fires start in engine compartments and surrounding areas. A tested and certified fire suppression system in combination with efficient fire detection, is the best first response in case of an emergency. Dafo Forrex Fire Suppression Systems response rapidly to any increase in temperature. The Dafo system is developed to be used worldwide in both cold and hot climate and designed after the International guidelines SPCR 183 and Swedish guidelines SBF 127, which requires 3L extinguishing agent for 1 m3 protected space.
 
This means that we leave nothing to chance, safety first! The Dafo system is designed to perform even under severe conditions in harsh environments.
The liquid agent extinguishes fire and effectively prevents re-ignition. 
A low pressure system demanding modest space and that operates down to -50o C.

Recycling machines

Technological progress gives us a more and more exciting life, but also more and more electronic waste. Demands for environmentally friendly recycling solutions are growing increasingly important. When installing recycling plants, it is a big investment and above all a big favour to the environment.

A fire can be a disaster both for a company’s economy and the environment. Therefore we have developed a design for fire fighting systems, specializing in recycling constructions for electronic waste, tyres, biomass etc. These suppression systems consist of two independent parts, one automatic and one manual system.

We also offer well proven vehicle fire suppression systems for mobile crushers, which can be installed either at the manufacturer or after delivery.

All our fire suppression systems are designed, installed and maintained in accordance with the appropriate standards.

Emergency Generators

Many business operations rely on emergency generators to secure critical functions within their organization. It is easy to ignore the fact that, as these units are driven by combustible engines, they also constitute a significant fire hazard.

Dafo Forrex Fire Suppression Systems response rapidly to any increase in temperature. The Dafo system is developed to use worldwide in both cold and hot climate. It ensures maximum protection while being much more economical than previously available solutions like water sprinkler, dry chemical or CO2-systems.

Components for vehicle fire suppression system

The environment in a vehicle is very demanding. Temperature differences, vibration and a demanding electrical environment means that the fire suppression systems on the vehicles need to be extra durable. Most components of our fire suppression systems are developed by us and made only for vehicle use. Many of the parts are tested and approved against strict vehicle norms and standards before they are put into use.

Control unit

Our control unit, model CV-01, has a separate display panel that can be mounted on the dashboard. The panel is connected to an control unit which is stored enclosed in a separate connection box, to which remaining equipment is connected to. The design offers a very flexible solution that facilitates the assembly and provides a secure and reliable design. 

Control unit

The panel is easy to customize for multiple languages so the same equipment can be used in different markets. The panel is equipped with alarm diode, triggering pushbutton.

LEDs indicate operating status and monitoring functions. Furthermore, there pushbutton for testing the recovery of the fire suppression system and a push button for manual release of the system.

Dafo also have other types of control units for surface or flush mounting. See separate leaflet.

Detector

In case of fire, it is important to detect it as soon as possible for the fire suppression effort to succeed. The choice of the detector should be done with great care. Dafo provides several options for detection, depending on the environment in which they will be used:

Line detector

Detector

Dafos line detector is a robust thermal detector designed to withstand the automotive environment. There is a cable that detects the fire over its entire length. Detection occurs when the temperature is about 180 ° C (356 ° F). It is easy to both install and maintain, because it is part of a monitored circuit.

Other options for detecting are the BD-P detector or IR detector. A large variety of accessories are available to ease mounting.

Forrex agent tank

Dafo has developed a wet chemical named Forrex specialized to take on fire in vehicles. The FORREX agent tank is developed by Dafo and has a unique design with great advantages for vehicle protection.

The tank is provided with an internal piston that releases the extinguishant. It provides large flows and an even spray pattern. The system also works if the vehicle has turned over.

The design allows the optimal placement even in space-saving vehicles. The containers are available in standard sizes from 5 to 25 liters (1,3 to 6,6 US gal) and can also be multiplied.

Pipes and nozzles

Dafos DW2 nozzle is a direct spray nozzle that is placed around the hazardous areas and is a vital part in the cooling effect of the fire suppression system. It has a protective cap to prevent dust from entering the distribution system and is space efficient.

The nozzles can be installed directly on the pipe or screwed in clutches. Dafo also has other nozzles in our range like our new mist nozzle DM8 that is efficient to take on fires in narrow spaces.

We use stainless steel piping or hydraulic hoses for the distribution of the extinguishing agent.
