HIGHLY INNOVATIVE TECHNICAL SOLUTIONS NOT SUBJECT TO FREE MARKET COMPETITION

The patented* MIX-IND® SYSTEMS consist of perforated ducts manufactured exactly like SPIROJET ducts, but designed using multiple patented* technologies that deliver significantly higher energy efficiency and comfort performance compared to even the most advanced traditional air diffusion systems. Although their unit cost is considerably higher than that of SPIROJET-type or similar perforated ducts, MIX-IND® perforated ducts often not only offer the highest performance available but can also reduce the total cost of the entire system. For the design of such systems, SINTRA offers an original technical support service that is both simple and highly effective, known as: ASSISTED DESIGN.

One of the best air diffusion products
Available on the Open Market

SPIROJET is a modern and user-friendly product. Manufactured in one-meter modules using VERDE SPIROPACK technology, it ensures optimal indoor comfort and uniform temperature distribution throughout the space. Its high induction rate prevents heat stratification. The modules are joined together using the new patented* TWIN-LOCK collars, which require no welding. Thanks to its highly competitive unit cost, exceptional induction performance, and high-quality components, SPIROJET perforated ducts are among the best air diffusion products currently available on the market.
