Frequently Asked Questions

Where is your product Manufactured?

Our HQ and manufacturing plant are both located in Italy. We also have offices in France, United Kingdom and the USA. Our goal is to open a manufacturing plant in the USA.

What equipment do you provide on projects utilizing MIX-IND®?

We provide insulated plenum sections, optionally with a fan and filter, and perforated ductwork. The plenums are used to connect our system to the air handling equipment. Our systems are compatible with AHUs, RTUs, FCUs, VAV boxes. It can also be installed independently with a fan & filter plenum. We remain vendor-agnostic and do not supply HVAC units or BAS/control systems.

Does this system work with Demand Control Ventilation?

This system is ideal for Demand Control Ventilation.

How does this compare with fabric duct solutions currently on the market?

Fabric duct requires higher airflow and produces minimal air induction in comparison, often leading to stratification. Unlike MIX-IND®, current fabric systems lack the mechanical capability to generate high-induction airflow.

How does MIX-IND® impact the overall design of other mechanical systems?

The impact varies based on project goals. For retrofits, we can design around existing equipment; for new construction, we are more than happy to offer recommendations on equipment sizing/selection and placement based on project-specific needs.

Do you work everywhere in North America?

Yes, we do.
