New CHALI brush duct system: VDE-compliant access in the middle of the room

The CHALI screed-flush brush duct system not only makes power and data cables disappear invisibly into the floor. Thanks to its special cover, it also ensures VDE-compliant electrical installation in the middle of the room. Der Bürstenkanal CHALI lässt Strom- und Datenkabel nicht nur unsichtbar im Boden verschwinden. Dank seiner Spezialabdeckung sorgt er auch mitten im Raum für eine VDE-konforme Elektroinstallation.

The new CHALI screed-flush brush duct allows power and data cables to disappear invisibly into the floor - and not just along walls and window fronts. With our flexible underfloor system, you can ensure VDE-compliant electrical installation in the middle of the room. This is made possible by the brush cover specially developed by us.

Maximum planning freedom for discreet power and data supply

CHALI gives you maximum freedom in room planning. We have developed the PUK cable outlet cover for our new brush duct. Because the brush outlet can be covered in just a few steps, you can install CHALI completely independently of the walkways in the middle of the room. No tripping hazards, no risk of accidents - the product is flush with the screed, barrier-free, and meets the highest safety standards. This has been confirmed by the independent testers of the VDE Institute with their test mark.
There are virtually no limits to your ideas for a discreet power supply in dry-cleaned rooms. Our new brush channel comes in a delivery length of 2 meters and can be extended indefinitely via connecting plates. You can cover it with carpet, linoleum, or wood. CHALI is loadable with an individual load of 2/3 kN and is therefore also ideally suited for office traffic loads.

Increased impact sound and reliable fire protection

Good impact sound insulation is essential in many buildings. That's why CHALI meets the strict requirements of the DIN 4109 test standard. The brush duct provides sound insulation of 53 dB on ceilings in office buildings and achieves sound insulation level II according to VDI 4100. Therefore, you receive a high-quality product with increased impact sound protection.
When developing a fire protection solution for the CHALI system, the standard Wichmann folding box was combined with PUK trusses. This makes CHALI a tested, high-quality fire protection system.

Freely combinable with existing PUK underfloor systems

The leveling feet, rubber sleeves, brushes, and other product components meet the usual high-quality standard of PUK. You can easily connect CHALI via empty pipes. Alternatively, connection to the existing screed-covered PUK underfloor system is possible.

Your advantages at a glance:

  •     VDE-compliant electrical installation in the middle of the room
