DEC Flexible Ducting Systems
ALUDEC®


ALUDEC® ducts are flexible, strong laminate ducts for various purposes.

The ducts consist of several layers of aluminium and polyester, with a spiral enclosed between the layer. The duct can be attached to round and oval connection parts without any problems. The fire resistance of the ALUDEC® ducts has been tested in several countries, according to current international standards. For specific information about the various ducts consult the product information page.

Applications in practice:
ALUDEC® AA3 & ALUDEC® 245:
  • General air supply systems, without special demands.
  • Air conditioning systems, without special demands.

    ALUDEC® 112:
  • Air supply systems, where a higher temperature resistance is required.
  • Air conditioning systems, where a higher temperature resistance is required.
