Prince Castle food holding bins provide the capacity
required for large foodservice operations while performing at peak energy efficiency. Each unit features two
individually controlled holding chambers. New Reli-ATemp ™ infrared heater technology holds product
temperatures more consistent within the designated
holding time than other types of heating systems. This
exclusive heater design spreads the heat evenly over the
entire food holding area, eliminating edge drop off.
Food is kept at the desired serving temperature.
