CombiTunnel ventilation For the ideal climate in your poultry house at all times – no heat or cold stress, increased welfare, higher performance

How to prevent heat stress: ventilation in tunnel mode Tunnel ventilation is the most simple and, at the same time, the most efficient ventilation system to create high air speeds at bird level. A high air speed will significantly decrease the temperature that is perceived by the birds (use of the windchill effect). Even in case of high temperatures and high humidity, the birds are thus able to transfer excess heat to the surrounding air. When temperatures continue rising, our RainMaker 2 pad cooling system can be activated. This system cools the fresh air to a temperature where the Large tunnel...

CombiTunnel ventilation Combination of two different ventilation systems to create one intelligent climate solution The CombiTunnel ventilation system from Big Dutchman is a very successful ventilation system that has proven its worth over many years. It creates perfect climate conditions for poultry anywhere in the world so your production process is secure. unnel mode T T unnel mode is activated when outside temperatures are high. This creates a good cooling effect while consuming little energy. ide mode S S ide mode is activated when outside temperatures are low. Since the fresh air is not...

How to use the birds’ heat efficiently: ventilation in side mode Side ventilation is the most comfortable ventilation system for even temperatures in the entire barn. The fresh air enters the barn along its entire length at once, with the air jets filling the entire room. The birds then heat up the cold and humid fresh air, thus drying it. This is the only way of completely absorbing the water vapour produced by the birds through ventilation without With side ventilation, the fresh air flows along the ceiling, where it warms up before it slowly drops down. causing excessive air movement in the...

The ViperTouch climate computer controls the CombiTunnel ventilation system Our modern climate and production computer ViperTouch ensures that the temperature in your barn is ideal at all times. This is made possible by a future-proof software and the use of sensors that determine important parameters such as temperature, humidity, CO ² concentration, NH³ concentration and air pressure. The sensors measure and check changes in the air and are the basis of any computer-controlled climate system. Big Dutchman offers a wide variety of sensors suitable for livestock buildings. Below, you will find...
