Pre-insulated fittings and ducts

ISOL is the program of pre-insulated channels and fittings, intended for both indoor (anti-condensation system) and outdoor (transport and maintenance of air temperature) use.

The system consists of an internal and an external spiral channel with an insulating rock wool mattress in between.

The nominal diameters always refer to the internal channel, regardless of the thickness of the insulation, which can be:

  • Insulation 25, with a thickness of 25 mm, ideal for anti-condensation systems.
  • Insulation 50, with a thickness of 50 mm, for the best insulating capacity.

The joint system is a nipple, with a SPIRO®system seal in EPDM rubber.

The standard diameters range from nominal 100 mm to 900 mm (always intended as internal diameter), for non-standard diameters, consult our technical-commercial office.
Executions in AISI 304 and 316 STAINLESS STEEL, COPPER, ALUZINK and PRE-PAINTED SHEET are available on request.
