How It Works

This building is all about performance and providing the best environment for your crop.  It's called the Air Envelope because it wraps your crop in an envelope of air.  The air is climate controlled and in constant circulation, which reduces hot spots and greatly extends storage life.

The industry's only Fully Vented Air Envelope system

Our heated air is calibrated to be one degree warmer than the potato pile with a ducted air distribution system to keep air moving over every square inch of the envelope cavity, including the walls and roof.  This is especially important in places that deal with extreme temperature swings.

Our Vent Design

The competition does not have a fully vented envelope, so return air takes the path of least resistance, leaving large areas of your building unvented and prone to condensation.  Not good!

The Competition

Solid Return Air Decks

Walk on our return air decks and you will feel how they are solid and easy to clean, with a built-in drain to make the job much easier.  The competitors' air decks rarely include a drain, sometimes just a vent, making them difficult to clean and prone to rust.
