Addressing Challenges in Railway Vehicle HVAC Systems with AirDIV’s Textile Air Ducts

In the realm of railway vehicle engineering, the challenges posed by HVAC (Heating, Ventilation, and Air Conditioning) systems are substantial and multifaceted. For decades, engineers have grappled with issues such as excessive weight, cumbersome installation processes, uneven air distribution, prohibitive costs, and spatial constraints within vehicles. These challenges not only impede efficiency but also inflate operational costs and compromise passenger comfort.

Enter AirDIV, a pioneering provider of textile HVAC ducts tailored for rail vehicles, including trains, trams, and metros.

The Problems of Traditional Rigid Air Ducts:

Heavy Vehicle: Conventional air duct systems contribute substantial weight to rail vehicles, impacting performance and fuel efficiency.

Slow Installation: Tedious assembly processes translate to increased labor costs and prolonged vehicle manufacturing.

Uneven Air Distribution: Inconsistent airflow within passenger saloons and cabins diminishes comfort and efficiency.
