ADVANCED FROST PROTECTION

AGI’s electric frost fans provide efficient and reliable protection against damage caused by frost in a variety of environments and temperatures. The custom-designed open impeller ensures efficiency in protecting frost prone crops, irrespective of the surrounding landscape. Our frost fans offer a greener alternative in frost fan technology and boast a coverage area of 7 to 9 hectares per fan and the lowest running costs in the industry.

AGI frost fans are manufactured to order and transported to site in modular form, before being assembled by our experienced field technicians.
