The system that defies the void
NASA had to keep the air inside a sealed space capsule clean.
Inspired by that technology, Sub-Zero built the same idea into your refrigerator.
Ripening fruit releases ethylene—a gas that makes everything near it ripen faster.
In a sealed fridge, it builds up, and your food ages before its time.
Every twenty minutes, Sub-Zero draws the air through, cleans it, and returns it.
The ethylene is gone before it can do harm, so each thing keeps to its own pace.
On the left, an apple after seven months in a sub-zero—wrinkled, but still whole. On the right, one after two months—still firm. Freshness preserved. Most apples don’t last a fraction of this. The difference is in the air.
The same cycle takes the odor with it. Nothing borrows another’s scent.
Open the door, and it is clean.
