Steam Cooking

Convection cooking in pressure-less steaming compartments will steam cook fresh foods or will steam defrost and cook frozen foods providing the maximum color, flavor and nutritional value with the least expenditure of energy and labor. The pressure- less steaming compartments on the VHX series, allows the operator to open and close the door anytime during a cooking cycle. The steam supply will shut off when the door is opened, then re-start when the door is closed.
