FarmMark has been conducting a trial with Brisbane Valley Protein for the new fans designed and manufactured by SKOV in Denmark. As part of the trial, two existing sheds had the end walls replaced and new fans inserted. The existing fans were replaced with variable speed fans and on/off fans. Results to date have demonstrated both an improvement in tunnel pressure, reduction in maintenance and significant reduction in energy consumption. For further details on the fan specifications and performance improvements, please contact a FarmMark representative.
