Tunnel Inlet Door

Huabo tunnel inlet door systems can be designed for one or two story chicken houses.

Better air mixing in house
1. Cyclonic air movement generates desirable airflow at bird level throughout the poultry house.
2. No more dead zones at the side and end walls, which are typical of curtain sidewall or double door houses.
3. Insulates at least 8 times better than a curtain during winter.
4. During tunnel-assist mode, cold air is directed away from the birds until it has mixed with house air.
