Perforated Ducts<\/p>\n

[\/vc_column_text][vc_column_text text_lead=”yes” uncode_shortcode_id=”435513″]<\/p>\n

One of the best air diffusion products on the open market.<\/strong>
SPIROJET<\/strong> is a modern and easy-to-use product. Manufactured in one-meter modules using green SPIROPACK<\/strong> technology, it ensures optimal indoor comfort and perfect temperature uniformity throughout the space.
Its high induction capacity prevents heat stratification. The modules are connected using the newly patented TWIN-LOCK<\/strong> collars, which require no welding.
Thanks to its highly competitive unit cost, exceptional induction rate, and high-quality components, SPIROJET perforated ducts<\/strong> rank among the best air diffusion products currently available on the market.<\/p>\n

SPIROJET perforated ducts are composed of a series of one-meter modules, each comparable to a traditional high-induction diffuser.<\/strong>
The diffusion element is the perforation itself, which can be applied to any module regardless of the duct diameter.
The air exiting the holes induces ambient air at a rate generally 30 times higher than the volume of supply air.
By increasing the outlet velocity through the holes, it is possible to boost induction\u2014often exceeding 50 air changes per hour (ACH)\u2014although this may reduce the diffuser\u2019s performance.
The diameter and number of holes applied to each SPIROJET module determine both its air throw capacity and its operating characteristics.<\/p>\n

Under normal operating conditions, the ambient air induced by the perforations ensures continuous ventilation of the duct\u2019s outer surface, effectively preventing condensation formation.[\/vc_column_text][\/vc_tab][vc_tab gutter_size=”2″ column_padding=”2″ title=”Perforation calculation” tab_id=”1563288676458-2-4″ slug=”calcolo-delle-forature”][vc_column_text uncode_shortcode_id=”187041″]<\/p>\n

The perforation layout of SPIROJET ducts is custom-calculated for each system using one of the most advanced CFD (Computational Fluid Dynamics) models available on the market, further enhanced by over thirty years of experience gained through the development of MIX-IND\u00ae technology.<\/strong><\/p>\n
