This machine has two zones, each zone is designated by the color of the bearings, black bearings for the front zone, and white bearings for the rear zone. It has a digital temperature readout with a mechanical temperature control. The roller grills come with NEMCO’s great roller grill features: grease seals and bearings for double protection against grease moving into the end panels and the chain, color-coded bearings to designate front and rear zones, and distributed-wattage elements that provide even temperatures across the entire roller. They are available with flat or slanted GripsIt rollers. The GripsIt coating features non-stick properties and a high-performance grip and abrasion-resistant additive.
