Gaseous fixed fire fighting system FK-RACK® we developed in-house and we manufacture it ourselves in our company.

It is a standalone, fully automatic, detection and fire fighting system designed for server racks 19" wide or wider. System FK-RACK® uses extinguishing agent HFC 236fa (hexafluoropropane) or HFC 227ea (heptafluorpropane). These substances are approved by relevant certification authorities with respect to the protection of environment. 

In addition, they comply with basic requirements of national as well as European legislation.

Function of the system FK-RACK:

The system FK-RACK® consists of fully equipped automatic system consisting of an all-in-one fire detection, control, evaluation and extinguishing unit. Larger server cabinets and side-by-side racks may be protected individually by additional auxiliary systems FK-RACK® formed only by detection, communication and extinguishing unit. This unit must always be connected to the FK-RACK® control unit. When fire is detected, all systems are actuated simultaneously. Life cycle of the system is 10 years from the manufacture date.


FM 200

Extinguishing agent is a colourless gas without odour. The extinguishing effect of FM200 is based on absorption of heat from the flames. It means that from the major part it is based on physical effects and from the minor part it acts on chemical basis.

HFC-236 FA

HFC-236 FA is a non-conductive, non-corrosive and non-flammable extinguishing agent with zero ODP value (i.e. it causes no damage the ozone layer). It is used in certified fire fighting systems named FK-KOMPLET®, which are designed and manufactured by our company.


  • easy installation and setup/commissioning
  • special highly sensitive detectors designed for switchboards
  • fast response to fire right inside the protected equipment 
  • does not cause damage data on data storage media
  • extinguishing agent is non-conductive and non-corrosive
  • may be used for extinguishing of electrical devices with rated voltage up to 1000 V



Assessment of the product conformance was performed by Strojírenský zkušební ústav, s. p. (Engineering Testing Institute) in compliance with the act No. 22/1997 Coll., based on the conformance assessment were issued the EC certificates of conformance No. E-31-00999-09 and E-31-01000-09. The system complies with requirements of the Directives of the European Parliament and of the Council No. 2006/95/EC and 2004/108/EC.
