Complement your choice of surface cooking options with the heavy-duty precision of a convection oven base. Hestan’s durable modular design works with any rangetop — from gas burners to charbroilers to French tops. Build a freestanding range or add to a custom suite. A two-speed high-efficiency convection fan ensures perfect heat circulation from 150º F to 650º F. Hestan’s innovative heat exchanger provides maximum heat transfer to the oven cavity. Meanwhile, the heavy-duty counterweighted door actually stays shut, keeping all that heat inside the oven.
