Energy efficient controllable exhaust-units for agricultural use

In optimising the ventilator blade and motor while improving the control strategy, the project has succeeded in developing a ventilation system for piggeries generating energy savings of 46% compared with current products in the market. The additional investment in the newly developed system will be repaid in less than three years. The prototype developed has been transferred to commercial production at SKOV A/S and will be marketed in the second half of 2010. The blade will be produced by MultiWing and the custom-made motor control by Motron, both Danish companies. The project won the 2010 Elforsk prize for its ability to fast-track new knowledge into use. (Energi 10)
