Vari-D System


Among our patents, Vari-D stands out to allow energy efficiency of ventilation systems and can be used with all DHI METAL, DHI TEXTILE or DHI PLASTIC diffusers. We are attentive to the environmental impact of our products and through this new technology it is possible to manage both the air flow and the pressure of the ventilation unit, guaranteeing a reduction in the energy absorption of the fans up to 80% and thus reducing costs management.

Duct dimensioning


For all customers, technicians and designers who need to verify the correct diameter size for their project, we offer our DHI diffuser sizing calculator. For your convenience, from the button below you can directly access the program, which is therefore useful for your preliminary design phase.
Our technical office is always available for further information and support for the final sizing of our ducts.
