A revolutionary automatic gas extinguishing system, intended for protecting small enclosed spaces in which computers, servers, electrical equipment, etc. are housed. The maximum volume of the enclosed space is 0.50 m3

Nowadays there is electronic equipment everywhere. It is important to take on board the fact that many fires break out through short circuits, and that they often occur at just the moment when nobody is present. Simply installing the Proteng ELECTRO in the compartment will avert such situations. This is a fully automatic system and it is easy to install.

The entire working principle is based on an 18 mm diameter polyamide hose that is 100 cm in length and is filled under pressure with the effective extinguishing agent FM-200, which is called Heptafluoropropane. At a normal temperature there is a constant 5 bar pressure. There is 250 g of the extinguishing agent in the hose. When the hose is heated during a fire, the pressure rises to 15 bar at a temperature of 100 °C. The system activates at 120 °C. The polyamide hose wall section that has become soft will burst exactly at the point with the highest thermal load, which will then release the extinguishing gas into the compartment. The gas reliably and effectively extinguishes the fire at its source. There is no damage to electrical components during extinguishing. The whole system is fully automatic, requires no control and activates immediately if a fire starts. This system protects you personally and your property 24/7.

The suitability for purpose of this installation is shown by the fact that our Proteng Electro system  is installed in nuclear power stations (e.g. Mochovce and Jaslovské Bohunice, Slovakia – Kalininskaja, Russia) – and in places where there is the highest level of emphasis on safety. This  system is installed in gas installations, electrical switchgear, and computer servers cabinets (e.g. the Johan Desmet Insurance Company's servers, Belgium), computers, domestic distribution cabinets, various other electrical installations, etc.

The advantages of the Proteng ELECTRO system

  • An unbelievably simple principle
  • Outstanding simplicity and flexibility of installation
  • Fires are reliably and effectively extinguished at their source
  • Self-activating, without need for any operation
  • No side effects
