Abstract
A pan chiller system eschews traditional methods of strapping refrigeration tubing upon an inner liner and obtaining temperature readings from a suction line. The disclosed embodiments overcome shortfalls in the related art by, inter alia, by artfully using a thermal retention assembly that retains refrigeration tubing in the middle of an inner liner. An inner liner may be filled with glycerin or similar products with the glycerin filling a temperature control bulb to obtain accurate temperature readings and avoiding the use of a suction line for such purposes. The disclosed embodiments may also include an air movement system moving cold air at the bottom of the pan and moving air upon the outer sides of the glycerin well and over the top of the well.
