Tunnel ventilation that actually performs in tropical climates

Fan static pressure, pad sizing and inlet placement for hot-humid regions where minimum ventilation isn't enough.

By HatchMatch Group Editorial Desk

In short

In hot-humid regions tunnel ventilation has to do real cooling, not just air exchange. That means fans rated at full static pressure with the pads wet, properly sized cooling pads (typically 10 cm thick, 0. 7 m² per 1000 m³/h), and inlets positioned for end-to-end laminar flow.

Get the pad sizing wrong and your wind-chill effect collapses on the hottest days — exactly when you need it.
