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 of said plurality of hollow divider bars includes an internal rib segmenting said each divider bar into an upper channel vertically displaced from a lower channel, said upper and lower channels in said each divider bar are longitudinally encircled and defined by opposite inner walls of said each 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 of said coolant between said upper and lower channels, said cutout encircled and defined by said opposite inner walls; 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,wherein said internal rib is integrally attached to said opposite inner walls. 2. The pan chiller system of claim 1 wherein said pan chiller unit is located remotely from said refrigeration package, said food well has a pair of opposed sidewalls and each of said divider bars extends from one of said pair of sidewalls to another of said pair of sidewalls. 3. The pan chiller system of claim 1 wherein said internal rib is arranged generally parallel to a bottom wall of said food well, and extends along a longitudinal axis of each of said divider bars. 4. The pan chiller system of claim 1 wherein an outer perimeter of each of said divider bars includes an axially extending stepped groove. 5. The pan chiller system of claim 1 wherein each of said divider bars further includes a pair of endcaps constructed and arranged for covering a first end and a second, opposite end of said divider bars. 6. The pan chiller system of claim 5 wherein one of said endcaps defines a pair of openings each aligned with one of said upper and lower channel and being constructed and arranged for receiving a corresponding conduit. 7. The pan chiller system of claim 1 wherein each of said divider bars further includes a pair of endcaps, one of the endcaps of each pair of endcaps defining at least one opening aligned with one of said upper and lower channel and being constructed and arranged for receiving a corresponding conduit. 8. The pan chiller system of claim 1 wherein said upper channels of said plurality of hollow divider bars are connected to lower channels of an adjacent divider bar of said plurality of hollow divider bars by a connecting pipe. 9. The pan chiller system of claim 1 wherein each of said divider bars further includes a fin extending from a top portion of said divider bars and axially extending along said divider bars parallel to a longitudinal axis of said divider bars and creating shoulders on both opposite sides of said fin along the longitudinal axis. 10. The pan chiller system of claim 9 wherein said fin extends at least as high as a top periphery of said food well. 11. The pan chiller system of claim 9 wherein said fin is centrally located on said top portion. 12. The pan chiller system of claim 1 wherein said food well includes an outwardly extending upper peripheral wall dimensioned for maintaining food temperature within said pan chiller unit. 13. A pan chiller system for a pan chiller unit for circulating a chilled liquid coolant, the system being configured such that the coolant remains a liquid during operation of the system, the pan chiller unit having an outer housing, a food well received within the outer housing and an insulating material therebetween, including: a plurality of hollow divider bars configured for directly receiving the chilled liquid coolant and arranged generally parallel to each other within the food well and an opening is defined between adjacent divider bars, wherein each of said divider bars includes a fin vertically extending from a top portion of said divider bars and extending along a longitudinal axis of said divider bars parallel to the longitudinal axis of said divider bars and creating shoulders on both opposite sides of said fin along the longitudinal axis; andwherein said fin extends generally vertically toward a top periphery of said food well, and is centrally located on said top portion, and said fin is solid from a top portion of said fin to a bottom portion of said fin, the bottom portion transitioning into said shoulders dimensioned for accommodating lips of food pans, and wherein each divider bar of said plurality of hollow divider bars includes an internal rib segmenting said each divider bar into an upper channel vertically displaced from a lower channel, said upper and lower channels are longitudinally encircled and defined by opposite inner walls of said each divider bar and said internal rib along a flow path of said coolant, wherein said internal rib is integrally attached to said opposite inner walls; and wherein an edge of each said internal rib includes a cutout constructed and arranged at an end of said divider bar for receiving said coolant and for enabling flow of said coolant between said upper and lower channels, said cutout encircled and defined by said opposite inner walls. 14. The pan chiller system of claim 13 wherein said fin extends one inch from said divider bars' top portion. 15. A pan chiller system for a pan chiller unit having an outer housing, a food well received within the outer housing and an insulating material therebetween, including: a plurality of hollow divider bars arranged generally parallel to each other within the food well and an opening is defined between adjacent divider bars, wherein each divider bar of said plurality of hollow divider bars includes an internal rib dividing said each divider bar of said plurality of hollow divider bars into an upper channel vertically displaced from a lower channel, said each divider bar configured for directly receiving a coolant, are longitudinally encircled and defined by opposite inner walls of said each divider bar of said plurality of hollow divider bars and said internal rib along a flow path of said coolant, wherein said internal rib is integrally attached to said opposite inner walls, and an edge of each said internal rib has a cutout encircled and defined by said opposite inner walls for enabling flow of said coolant between said upper and lower channels and an outer perimeter of each of said divider bars includes an axially extending stepped groove for accommodating food pans while keeping the walls of said divider bar as close to walls of the food pans as possible for efficient energy transfer, and an upper surface of said divider bar is dimensioned for accommodating lips of the food pans on a top edge of said divider bar, and directly receives and supports the lips of the food pans, said divider bars having a narrower width at an upper end relative to a wider lower end, the base of said wider lower end wider than said axially stepped groove, and a fin vertically extending from a top portion of said divider bars and extending parallel to a longitudinal axis of said divider bars, wherein said coolant flows directly into said lower channel and exits through said upper channel; 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, and said divider bar walls, in each said divider bar, being continuously connected and integrally formed for defining inner hollow cavities of said upper and lower channels. 16. The pan chiller system of claim 15 wherein each of said divider bars further includes a pair of endcaps constructed and arranged for covering a first end and a second, opposite end of said divider bars, one of said endcaps defining a pair of openings constructed and arranged for receiving a corresponding conduit for delivering said coolant.
