Combidec 2300

Combidec 2300 ducts are solid, very flexible, extremely strong laminate ducts for different ranges of application. The base of the Combidec series is an aluminum/polyester laminate duct with an outer jacket of copolymer. The ducts can be attached easily to round and oval connection parts without any problems.

The fire resistancy of the Combidec 2300 ducts have been tested in several countries, according to current international standards. Because of the “sandwich construction”, the different layers of polyester and aluminium are overlapping each other completely. In case of fire, the system is able to function longer. The outer jacket is wear resistant and steam tight.

the advantages compared to pvc ducting

  • higher temperature resistancy
  • less smoke development in case of fire

the advantages compared to aluminium laminated ducting

  • higher tear resistancy
  • better mechanical protection against external influences
  • better resistance to local loads

application

  • steam return lines
  • applications where good mechanical strength is required
  • good to use in devices
  • to use in devices for mechanical ventilation
