ISDR is an innovative and durable insulated piping system. This high quality solution is developed to satisfy the increasing demands concerning thermal insulation and noise levels in living areas for aero-technical installations with heat recovery.

• Installation with heat recovery.
• Easy to install by means of flexible rubber connections.
• Easy to shorten precisely with few rest waist.
• The flexible connections guarantee an air tightness of the highest level.
• Conical connection pieces for connection between any heat recovery unit with roof or wall passages.
• Sound attenuation through the wall of 14dB(A) for ISDR 200/170 and 20 dB(A) for ISDR
• 160/125 (according to DIN-EN-ISO 51235:1999)
• High thermal insulation value to prevent condensation
• A minimal amount of suspension clamps have to be used for mounting. Install a suspension clamp every 2 metres.

• Outer sheath made of Polyethylene (HDPE).
•  Inner sheath made of insulating Polyolefin foam, vapour-tight with closed cellular structure.

•  No risk of corrosion, mosses or mould thanks to the hydrophobic inner sheath.

•  Temperature range from -40°C to +95°C.

•  Thermal conductivity coefficient 0,040 W/mK

• Insulated bend ISDR BD90/45°
• Connection piece ISDR M
• Wall passage ISDR BLR
• K-flex tape for insulation of the connection to the unit and towards the roof pass-through.
• OBMC 160 clamp for duct mounting with an external diameter of 160 mm.
• OBMC 200 clamp for duct mounting with an external diameter of 200 mm.

 ISDR 200/170

Explanation:

ISDR = duct type

200 = diameter of outer sheath

170 = diameter of inner sheath
