The TurboChef HHC2020 VNTLSS countertop conveyor oven has a 20-inch chamber for cooking pizza, sandwiches, and cookies. Its top and bottom air impingements are controlled independently by the user, and the recirculating impingement airflow system has variable speeds to heat a variety of product. Idle mode goes into effect when the oven is not in use to conserve energy. To ensure the components are running properly, self-diagnostics are built into the unit. For durability, the interior and exterior are constructed of stainless steel, and the covers and panels are cool to the touch to protect the user from burns. Using software, the conveyor belt can be fed through the right or left side. This TurboChef HHC2020 VNTLSS conveyor oven comes with two 6-inch extensions for the conveyor.
