The unit is a boilerless, self-cleaning, combi oven designed for steaming and convection cooking either separately, sequentially or combined. The combi oven has live-steamsystem that generates steam directly into the cooking chamber, for faster heating and reheating without requiring a stand-by mode. An award winning Multi-Eco system simultaneously pre-heats incoming water and cools outgoing condensate to reduce energy and water consumption. The oven fits 20 full size sheet pans or 40 steam table pans.
