Jockey Box Cold Plate - 8" x 12" Single-Circuit AluminumThe 8" x 12" Single Circuit Cold Plate is the core cooling component for portable draught systems and jockey boxes. Constructed from high conductivity cast aluminum with an internal stainless steel beverage line, it uses ice to rapidly drop the temperature of beer or soda as it flows to the tap. This single circuit model is designed to chill one beverage line effectively, providing a consistent, ice cold pour even if the keg is at room temperature.
