Double wall circular insulated spiral ducts are used to reduce possible heat dispersion in civil and industrial air-conditioning systems.
Their thermal insulation, anti-condensation and airtightness characteristics make these ducts particularly suitable for outside applications.
The duct is made of two concentric spiral pipes in galvanised sheet iron, with a gap insulated with high density mineral wool, 25 and 50 mm thick, perfectly separated from the air flow.
