Preinsulated ducts

• Straight ducts with a length >= 900 mm are regarded as STRAIGHT CONNECTION PIPES.
• Straight ducts with length < 900 mm are regarded as FITTINGS.
• We produce the straight ducts in L sections=1500 mm.
• If you order a rectangle with a length exceeding 1500 mm, it will be produced in sections of 1500 mm + the resulting rest.
• It is possible to produce a duct longer than 1500 mm.
• All ducts have stiffening “riffles”.
• The ducts are ended with “fixed” mounting frames.
• There is a possibility to produce a loose frame : designation “PSL”.
