KTL-SD • Rectangular ducts

Rectangular duct, length 2,4 m, in KTL coating steel (15µm). The duct is protected against the cement screed thanks to KTL coating.

• Ventichape

• These channels are used to establish a connection between the auxiliary collector (galvanized duct) and the main collector
• The channel consists of one piece and is laser-welded, which guarantees complete airtightness
• The rectangular channel of 200 x 60 x 2400 mm is almost the equivalent of a spiral duct of diameter 125 and can therefore handle flow rates of up to 150 m³/h (speed of ± 3.5 m/s)
• The rectangular channel of 200 x 80 x 2400 mm is almost the equivalent of a spiral duct of diameter 150 and can therefore handle flow rates of up to 225 m³ / h (speed of ± 3.5 m / s)

• Rectangular duct in KTL coating steel (15µm); the duct is protected against the cement screed thanks to KTL coating (Maximum load 80 kg/cm²)
