Frost fans play a vital role in protecting valuable crops from frost damage. To help growers maximize their investment, we’ve compiled answers to the most common questions about selecting frost fan systems.
There are two main types of frost fans used for crop protection:
The key differentiators are the power source (electric vs engine-driven) and whether the fans are stationary or portable. Both types are designed to circulate warm air and disrupt temperature inversions to prevent frost settling on crops.
So in summary, growers can choose between electric grid/generator-powered fans or portable engine-driven fans based on their specific power availability, crop layout, noise considerations, and desired coverage area per fan unit.
Diesel, gasoline, propane, liquid petroleum gas, natural gas, or electricity.
Although some manufacturers did not list the coverage area of their fans, but based on the data available, the range of coverage is from 4 hectares (Agrofrost Wind Machines) to 9 hectares (AGI Electric Frost Fan). For more details, see frost fans ranked by coverage area.
Only four manufacturers posted noise levels. The reported noise levels range from as low as 48 dB (Aria Antibrina) up to 66 dB (Jackrabbit Cold Air Drain). For further detail, see the frost fans ranked by noise level.
