Roxell has launched a new tunnel fan for poultry housing, with variable speeds to cope with changing weather conditions.
The Oxsano is made from fibreglass so it doesn’t rust and offers high energy efficiency, the company said. The fan has an aerodynamic design and with an airflow of 30 300 CFM and an efficiency ratio of 20 CFM/watt.
Variable speed is made possible by the speed controller in the motor. “A very effective way to cool a chicken’s body is to move air,” said Frank Hartmann, marketing manager at Roxell. “In a house, you create that optimal ‘wind chill effect’ with high-capacity tunnel fans. But there is also an increasing awareness of the energy costs of ventilation. For an energy-conscious poultry farmer, variable speed ventilation is therefore a logical next step. An engine that adjusts the speed to the required load will consume much less energy.”
