Orchard-Rite Wind Machine for Vineyard Frost Protection

Overview

Orchard-Rite wind machines are propeller-driven frost protection systems widely used in California and Pacific Northwest vineyards, orchards, and vegetable production. The machines mix warmer air above the inversion layer down into the frost-susceptible crop canopy. A single unit protects 10 to 20 acres depending on site topography and temperature differential. They are most effective in radiation frost events where an inversion layer exists. Automatic thermostat start allows unattended operation, which is critical for early morning frost events that occur without advance warning.
