Commercial Grills also known as Commercial Griddles are a staple for most food service operations. Commercial Griddles or Commercial Grills are offered in gas and electric units. There are two types of Commercial Gas Griddles: manual and thermostatically controlled. A manual controlled commercial griddle has a control for the flame only. This type of griddle is not the preferred griddle when cooking temperature sensitive foods. A thermostatically controlled griddle gives the operator the ability to control the surface temperature. Electric griddles always have a thermostatically controlled surface. Thickness of the grill surface and the depths (front to back) of the griddles will vary from manufacturer to manufacturer. The thicker the surface plate the more heat retention the griddle has. Commercial Grill Manufacturers offered within this group are: Accutemp, APW, Cadco, Equipex, Imperial, Rankin, and Star.
