How many acres do the units cover, what are the dimensions of the units, and how much do the units weigh?

Gas engine, tractor PTO, electric motor, and temperature controlled auto-start are available power options. The Power Options page provides additional information about available power options.
What size tractor do I need for the PTO model?
The #925 requires a minimum 10HP at 540 RPM, the #1550 a minimum 15HP at 540 RPM, and the #3510 a minimum 35HP at 540 RPM.
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. Please see the About the Product page for information about how the Cold Air Drain® works.
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. Please see the About the Product page for information about how the Cold Air Drain® works.
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. Please see the About the Product page for additional information about how the Cold Air Drain® works.
