The Limpet Plate Heater is a 1m x 1.2m microprocessor-controlled heating plate with two heating zones that are used to warm viscous products, such as syrups and fats, usually in plastic pails or small containers. Once the containers are in place, the unit can be covered with an insulated cover. It typically takes only a few hours for the product to achieve the necessary liquidity, so that the containers can be emptied with minimum waste.
