How can the Cold Air Drain move so much air, yet use so little fuel?
The octagonal wind tunnel design, over 85-90% efficient propellers, and customized frost protection system designs for optimal placement allows for the Cold Air Drain to obtain maximum efficiency.
Do you add heat to the units or do they just move air?
The Cold Air Drain moves air with propellers through the wind tunnel housing.
Does the Cold Air Drain® blow up or down?
The Cold Air Drain pulls in the coldest air from along the ground and thrusts it upwards.
When the cold air is sent up does it fall back down?
No. The cold air is mixed with the warmer, lighter air from above allowing it to continue rising. Ultimately, the cold air is dispersed into the upper inversion layer and will not fall back down.
Is the Cold Air Drain a traditional wind machine?
No. The Cold Air Drain is designed to work in low areas where cold air accumulates. Please see the Cold Air Drain vs Wind Machine section.
Will the Cold Air Drain work for row crops?
The Cold Air Drain® generally protects crops of 12-18 in or higher.
Can the Cold Air Drain be used with other types of frost protection?
Yes. The Cold Air Drain can be used alone or with heaters, wind machines, and sprinklers. Please contact a Jackrabbit representative to determine the best frost protection plan for your site.
Who has Cold Air Drain units protecting their crops? Where are these units located?
The Cold Air Drain protects a wide variety of crops that range from small, local farms all the way to international commercial enterprises
How do I know if the Cold Air Drain will work for me?
Jackrabbit conducts a Computerized Frost Analysis to recommend a customized system design. See the Contact Section at the end of this page for more information.
How can I tell if my unit is working?
Temperatures in lower, frost-prone areas will be more similar to higher, non-frost areas when the Cold Air Drain is operating. Crop yields will be more consistent throughout the protected area.
