Propokan Pro System – Technical Solution

The smoke extraction and ventilation ducts system is designed to transmit smoke, hot gas and flame from the sector to the sector, and bring fresh air to the fire sector. For this reason, it is necessary to provide fire protection of these systems for the safety of life and of course the protection of facilities and property.

European and domestic standards (SRPS) EN 1366-1 and (SRPS) EN 1366-9 aim to prescribe the minimum requirements that it intends to:   

  • Limitation of smoke spread through the duct system in the building during a fire  
  • Limitation of fire spread through duct systems in a building during a fire
  • Enabling the fresh air supply to the object during the evacuation   
  • Enabling the air duct system in the building to provide an additional purpose for smoke control    

Propokan system for fire protection of ventilation and smoke extraction ducts intended for supply and for the evacuation of smoke, ensures the maintenance of their integrity and cross-section within the fire sector, in order to allow maximum smoke flow that can be driven from the point of fire.

Propokan system offers consultants, designers, and contractors an effective way of protecting smoke extraction and ventilation ducts. Provides fire resistance of 120 minutes using locally produced galvanized ducts (rectangular and circular cross-section) protected by fire protection coating. The system has been tested in ILAC and MRA accredited laboratory FIRES in accordance with international standards EN 1366-1, EN 1366-9 and EN 13501-4 and application in the territory of Republic Serbia is approved by the competent Ministry.

PROPOKAN protection with intumescent coatings offers numerous advantages compared to other fire protection systems, and it is especially important that it is an environmentally friendly system based on materials that do not pollute but protect the HCFC environment. The application of this fire protection system provides standardized construction and installation of smoke ducts according to DW 144, provides protection of duct hangers on which there is a load that is not achieved with other protection systems. The most important thing in case of fire is for the ducts to keep their own INTEGRITY and STABILITY in order to enable the smooth flow of smoke, and thus justify its function, which is fully achieved by this protection system. Fireprotected, intumescent coatings are water-soluble, their application is fast and safe for people and the environment, and the protection results are extremely effective. Unlike other fire protection systems, this system achieves more effective results in a much shorter time and with the saving of space and financial resources. PROPOKAN SYSTEM of protection guarantees 120 minutes of protection in case of fire. It saves space because it does not reduce the level of the garage, nor does it burden the construction of the ducts, and thus does not increase the square footage of protection. It is more visually attractive because RAL is possible, ie it is possible to apply the final paint of the investor's choice. This protection system saves work time, which is 60 to 70% shorter than other protection systems. And last but not least, the price of this protection system is lower than other fire protection systems.
