MegaFans which were a joint design with NASA comprise fans of up to 10 blade design with diameters up to 24 feet in diameter and they are used to cool large premises in the summer and more evenly dissipate the heat in the winter. The magazine 'Energy Efficiency NoW' recently ran an editorial on the MegaFans entitled 'Efficiency in the workplace is a breeze', written by ACP&D Limited's Managing Director, Clive Pimlott. Below are the three pages of the article that appeared. The whole publication is available for download on the right hand side of this page.
