All NU-VU ovens feature our highly effective and patented V-Air® technology. This time-tested technology over 30 years old creates faster bake times than any convection oven because of the V-Air® perfect heat distribution throughout the oven...top-to-bottom, side-to-side, and front-to-back. With V-Air®, the baker does not have to turn sheet pans or open the oven doors during a bake cycle. This results V-Air® in better quality bakery products, and savings in labor and energy.
