Combination Steam Ovens are a unique style of convection oven that steams, poaches, roasts, broils, bakes and rethermalizes. Combination Ovens combine three great modes of cooking in one oven – steam, hot air, and a combination of both. The Combi mode eliminates the need for basting roasts, reduces shrinkage while giving perfect browning and is ideal for baking hard crusted breads. Roasting in Combi oven mode reduces shrinkage 20% to 30% (and food cost) yielding a juicier product.
