What Sintra does

Sintra S.r.l. - Società Benefit is an Italian manufacturer of perforated metal ducts and air-treatment systems, headquartered in Fontaneto D'Agogna (Novara), with subsidiaries in Bry-sur-Marne, France (SINTRA FRANCE S.A.S.) and the United States (SINTRA USA, established 2019). The company is privately held, controlled by ZAMBOS HOLDING S.R.L., and has 11-50 employees. It became a Benefit Corporation on 20 May 2021.

The core offering is built on founder Marco Zambolin's 1981 MIX-IND patent, which displaces traditional diffusion with ambient air pulsion: perforated ducts (PULSORI/DLP) generate a pressure field along their axis that moves the entire air mass, yielding temperature homogeneity within ±1°C regardless of building height, destratification above 40m, throw distances up to 100m, and up to 80% fan-energy reduction via the QPE variable-airflow system. The second product line, SPIROJET, uses SPIROPACK-manufactured metal ducts with patented TWIN-LOCK weld-free collars and is sold via an online configurator on the open market. Supporting technologies include VARIWIND (cold-air barrier at industrial doors), VARIBOOST, VARITRAP, BIMODULAIR and VARIPULSE. Sintra holds ISO 9001, ISO 50001 and IQNET certifications.

Sintra operates an enterprise sales motion in which custom MIX-IND systems are co-designed via a free Assisted Design service (environmental diagnostics, risk analysis, performance analysis); revenue derives from hardware sales of patented duct systems and adjacent professional services, supported by free three-tier training programs, self-training videos, and case-study content. Customers span automotive (PSA Group for 30+ years, Fiat, Iveco), swimming pools (Yves Blanc, Gussago), restaurants (Eataly Bari, Autogrill Villoresi Est), and broader industrial/commercial facilities, with 15,000+ systems installed across its European and North American footprint.

Core offering

Sintra designs, manufactures, and sells perforated metal duct systems for ambient air pulsion and supply air diffusion. The company offers two main product lines: the proprietary MIX-IND® (PULSORI®) system for high-performance air pulsion, and the SPIROJET open-market perforated duct line. Both lines are used to provide uniform climate control and destratification in industrial, commercial, and sports facilities, and the company also provides free assisted design services for project specification.

Product overview

Sintra is a leading European manufacturer of perforated metal ducts for ambient air pulsion and supply air diffusion. The company offers two main technology lines: (1) MIX-IND® patented systems (PULSORI®) for high-performance air pulsion with superior energy efficiency and comfort, incorporating QPE technologies for next-generation applications; and (2) SPIROJET perforated ducts for air diffusion using SPIROPACK technology, available on the open market. Both product lines share the TWIN-LOCK collar connection system. Sintra also offers VARIWIND external air barriers for cold air infiltration control. The portfolio ranges from industrial applications (automotive, warehouses) to commercial settings (swimming pools, restaurants, shopping centers).

Products and services

• MIX-IND® Perforated Duct Systems Patented perforated duct system for ambient air pulsion that creates a pressure field along its axis to set the entire ambient air mass in motion, delivering temperature homogeneity within ±1°C regardless of building height, complete destratification for buildings over 40m, and up to 100m throw distance. Designed for industrial, commercial, and sports facilities.
• SPIROJET Perforated Ducts Modern perforated duct system manufactured in one-meter modules using SPIROPACK technology, offering high induction rates (30:1 ambient to supply air ratio), modular assembly via patented TWIN-LOCK collars without welding, and competitive pricing for open-market air diffusion applications.
• VARIWIND External Air Barrier External cold air barrier system using untreated outdoor air to reduce cold air infiltration through industrial doors and loading docks without thermal energy consumption, featuring zinc-magnesium alloy construction.
• QPE (Quality Performance Efficiency) Systems Patented next-generation multifunction systems with high energy and comfort performance, enabling variable airflow from 20-100% without performance loss and up to 80% reduction in fan energy consumption.
• BIMODULAIR Super-Ventilation System Super-ventilation system for summer desuperheating producing 2,000,000 m3/h (50 vol/h) operating on solar energy, providing cooling without conventional refrigeration for large-volume industrial buildings.
• Assisted Design Service Free technical support service including environmental diagnostics, technical orientation, risk analysis, and performance analysis, supporting the sale and deployment of proprietary MIX-IND systems which require specialized design. Provided to engineering firms, HVAC contractors, and building owners.
• Technical Training Program Three-level free technical training program covering air pulsion technology principles, next-generation system design, and application techniques, held at company facilities with hands-on demonstrations to support market education and adoption of proprietary technologies.
