Straight ducts, length 2,000 mm

Straight metal fire protection duct BKI, 2,000 mm length, for encapsulation of fire loads with active flame retardation.

Application area:

The fire protection duct BKI is suitable for cables, flammable pipes and non-flammable pipes with flammable synthetic rubber insulation. The duct can be guided through fire-resistant solid and light dividing walls and even act as a cable platform. It is specially designed for installation in escape and rescue routes.

Field of Application:

Permissible filling of the BKI fire protection duct in rectangular cross-section shape:
- All cables and cable support systems, optionally with cable support structures
- Closed piping systems (at least normally flammable) ≤ DN 100 for drinking water, heating and cooling systems each with a maximum operating temperature of ≤ 80 °C
- Flammable pipes (at least normal flammability) and non-flammable pipes with flame-retardant insulation - insulation thickness ≤ 25 mm
- Copper pipes ≤ DN 80 with flame-retardant insulation - insulation thickness ≤ 25 mm

Advantages:

The innovative intumescent inside the duct expands in the event of a fire and actively stops the fire from spreading
Low space requirement thanks to much thinner wall thickness compared to conventional ducts
Fast and easy application thanks to pluggable and self-sealing components
Easy installation including directly on ceilings and walls
Dust-free and clean assembly
Quick and easy retrofitting possible
Retains its shape and is easy to access and maintain
Low tare weight

Advice:

Please observe the respective proof of use before installation and fit according to specifications!

The total permissible weight with direct placement of cables and pipes is 34 kg/m.
