Big Dutchman’s CombiTunnel ventilation is a strategic combination of wall inlets and tunnel doors. This ensures steady control of climate and environmental conditions for your birds. CombiTunnel ventilation works best in regions that have large fluctuations in temperature (hot humid summers and cool winters).
Side mode uses wall inlets during cooler weather, while tunnel mode kicks in during hot sticky periods. You can control both systems with ViperTouch, which automatically switches between the two ventilation systems as needed.
