1. A pan chiller system comprising: a refrigeration package having a condensing unit, a heat exchanger and a pump for circulating a chilled liquid coolant such that the coolant remains in its liquid state during operation of said system; a pan chiller unit in fluid communication with said refrigeration package and having an outer housing and a food well received within the outer housing;a plurality of hollow divider bars arranged within said food well and an opening is defined between adjacent divider bars, wherein each divider bar is configured for directly receiving the liquid coolant chilled and circulated by said refrigeration package, each divider bar includes an internal rib segmenting said divider bar into an upper channel vertically displaced from a lower channel, said upper and lower channels are longitudinally encircled and defined by walls of said divider bar and said internal rib along a flow path of said coolant;an edge of each said internal rib includes a cutout constructed and arranged at an end of said divider bars for receiving said coolant and for enabling flow between said upper and lower channels, said cutout encircled and defined by walls of said divider bars; andsaid divider bar walls enclosing said upper and lower channels, having a first surface being in direct contact with the coolant, and an outer shell opposite said first surface, being configured for directly supporting a food pan. 2. A pan chiller system for a pan chiller unit for circulating a chilled liquid coolant, the system being configured such that the coolant remains liquid during operation of the system, the pan chiller unit having an outer housing, and a food well received within the outer housing, including: a plurality of hollow divider bars configured for directly receiving the chilled liquid coolant being circulated by the pan chiller system and arranged generally parallel to each other within the food well and an opening is defined between adjacent hollow divider bars, wherein each hollow divider bar includes: a top portion;a fin vertically extending from the top portion;a hollow bar longitudinal axis;said fin extending along a fin longitudinal axis parallel to the hollow bar longitudinal axis; andsaid fin creating shoulders on the top portion on both opposite sides of said fin along the fin longitudinal axis, wherein said fin extends generally vertically toward a top periphery of said food well, and is centrally located on said top portion;spaced apart walls;an upper channel;a lower channel; andan internal rib extending between and connecting the spaced apart walls to create said upper channel and said lower channel through which the chilled liquid coolant flows and is in direct contact with an interior surface of said spaced apart walls, an end of the upper channel including a coolant flow opening and an end of the lower channel including a coolant flow opening, the internal rib including an upper surface and a lower surface, wherein the chilled liquid coolant flowing through the upper channel is in direct contact with the upper surface of the internal rib, and the chilled liquid coolant flowing through the lower channel is in direct contact with the lower surface of the internal rib; andwherein the chilled liquid coolant flows through the upper channel and the lower channel of each of said hollow divide bars before leaving each of said hollow divider bars. 3. A pan chiller system comprising: a housing within a food well, the food well formed in part by a first hollow divider bar and a second hollow divider bar arranged generally parallel to and spaced apart from the first hollow divider bar to provide a food pan receiving opening between the first hollow divider bar and the second hollow divider bar,wherein the first hollow divider bar includes a first internal rib extending between and connecting spaced apart walls of the first hollow divider bar to divide the first hollow divider bar into a first upper channel for flowing chilled liquid coolant and a first lower channel for flowing chilled liquid coolant, wherein the first internal rib includes an upper surface and a lower surface, wherein chilled liquid coolant flowing through the first upper channel is in direct contact with the upper surface of the first internal rib, chilled liquid coolant flowing through the first lower channel is in direct contact with the lower surface of the first internal rib; wherein the chilled liquid coolant flows through the first upper channel and the first lower channel before leaving the first hollow divider bar;wherein the second hollow divider bar includes a second internal rib extending between and connecting spaced apart walls of the second hollow divider bar to divide the second hollow divider bar into a second upper channel for flowing chilled liquid coolant and a second lower channel for flowing chilled liquid coolant, wherein the second internal rib includes an upper surface and a lower surface, wherein chilled liquid coolant flowing through the second upper channel is in direct contact with the upper surface of the second internal rib, chilled liquid coolant flowing through the second lower channel is in direct contact with the lower surface of the second internal rib; and wherein the chilled liquid coolant flows through the second upper channel and the second lower channel before leaving the second hollow divider bar. 4. The pan chiller system of claim 3, further comprising: a flow connection between the first hollow divider bar and the second hollow divider bar for flowing chilled liquid coolant from the first hollow divider bar to the second hollow divider bar. 5. The pan chiller system of claim 4 wherein the flow connection runs from the first upper channel to the second lower channel. 6. The pan chiller system of claim 4 wherein: an end of the first upper channel includes a coolant flow opening and an end of the first lower channel includes a coolant flow opening;an end of the second upper channel includes a coolant flow opening and an end of the second lower channel includes a coolant flow opening. 7. The pan chiller system of claim 6 wherein chilled liquid coolant flows into the coolant flow opening of the first lower channel, along the first lower channel, up into the first upper channel, along the first upper channel, out through the coolant flow opening of the first upper channel, along the flow connection and into the coolant flow opening of the second lower channel, along the second lower channel, up into the second upper channel, along the second upper channel and out through the coolant flow opening of the second upper channel. 8. The pan chiller system of claim 3 wherein chilled liquid coolant flows in one direction along the first hollow divider bar through the first lower channel and in an opposite direction along the first hollow divider bar through the first upper channel. 9. The pan chiller system of claim 8 wherein chilled liquid coolant flows in one direction along the second hollow divider bar through the second lower channel and in an opposite direction along the second hollow divider bar through the second upper channel. 10. The pan chiller system of claim 3 wherein: the first hollow divider bars includes a first fin extending vertically upward and along a longitudinal axis of the first hollow divider bar to create shoulders on both opposite sides of the first fin;the second hollow divider bars includes a second fin extending vertically upward and along a longitudinal axis of the second hollow divider bar to create shoulders on both opposite sides of the second fin.
