Refrigeration units and door systems for refrigeration units are provided. A door system for a refrigeration unit includes an outer frame and at least two sliding doors having the same size. Each door can include inner, outer, upper and lower sides that can have side outer surfaces presenting a seal profile that permits each door to seal when in a closed position. Each door can include pins extending outward from side outer surfaces of the upper and lower sides. The door system can include two parallel running rails within the outer frame. Each rail can include an upper sliding groove in which the pins of the sliding door run when the sliding doors move to an open position and a plurality of seating grooves that open up to the upper sliding grooves and extend downward from the upper sliding grooves in which the sliding doors reside in a closed position.

1. A door system for a refrigeration unit comprising: an outer frame for holding sliding doors;at least two sliding doors having the same size, each door comprising: a frame with an inner side, an outer side, an upper side and a lower side and one or more slider guides on a top surface of the inner side, the slider guides serving as support for the other sliding door when the other sliding door is in an open position;the inner side, outer side, upper side and lower side having side outer surfaces that present a profile that permits each door to seal tightly when in a closed position;pins extending outward from a side outer surface of the upper side and a side outer surface of the lower side of the frame so that the ins extend in the same plane as the respective sliding door;two parallel running rails within the outer frame, the rails aligning with the upper and lower sides of the sliding doors, each rail comprising an upper sliding groove in which the pins of the sliding door run when the sliding doors are being moved to an open position and a plurality of seating grooves that open up to the upper sliding grooves and extend downward from the upper sliding grooves, the pins residing in the seating grooves when the sliding doors are in a closed position;the one or more slider guides being positioned on the frame of each sliding door to aid in preventing the pins of one of the sliding doors being opened from entering the respective seating grooves in which the pins of the other closed sliding door still reside; andthe sliding doors residing in the same plane when the sliding doors are in a closed position and the sliding doors residing in two parallel planes when one of the sliding doors is in an open position. 2. The door system according to claim 1, wherein each of the sliding doors comprises a window held within the frame. 3. The door system according to claim 2, wherein the window comprises a transparent glass. 4. The door system according to claim 1, wherein each of the sliding doors comprises a handle disposed on an upper surface of the outer side of the frame. 5. The door system according to claim 1, wherein the frame of each of the sliding doors comprises a metal. 6. The door system according to claim 1, wherein each of the seating grooves in each of the rails is slanted toward a center of the rails. 7. The door system according to claim 6, wherein two of the seating grooves are on one side of the center of the respective rail and two of the seating grooves are on an opposite side of the center of the respective rail with each of the seating grooves slanted toward a center of the respective rail. 8. The door system according to claim 6, wherein each rail comprises two rail end pieces with each rail end piece having a slanted seating groove therein with the slanted seating groove slanted toward the center of the respective rail. 9. The door system according to claim 8, wherein each rail comprises a rail center piece that has two seating grooves slanted toward each other, the placement of the rail center piece within the respective rail aligns the slanted seating grooves within the rail center piece so that the slanted seating groove are slanted toward the center of the respective rail. 10. The door system according to claim 9, wherein each rail comprises two middle rail pieces with one middle rail piece between one rail end piece and the rail center piece and the other middle rail piece between the other rail end piece and the rail center piece, the middle rail pieces providing linear guide surfaces on which the sliding doors run when moving to an open position. 11. A door system for a refrigeration unit comprising: an outer frame for holding sliding doors;at least two sliding doors having the same size, each door comprising: a frame with an inner side, an outer side, an upper side and a lower side;the inner side, outer side, upper side and lower side having side outer surfaces that present a seal profile that permits each door to seal tightly when in a closed position;pins extending outward from the side outer surface of the upper side and the side outer surface of the lower side of the door so that the pins extend in the same plane as the respective sliding door;two parallel running rails within the outer frame, the rails aligning with the upper and lower sides of the sliding doors, each rail comprising an upper sliding groove in which the pins of the sliding door run when the sliding doors are being moved to an open position and a plurality of seating grooves that open up to the upper sliding grooves and extend downward from the upper sliding grooves, the pins residing in the seating grooves when the sliding doors are in a closed position; andthe sliding doors residing in the same plane when the sliding doors are in a closed position and the sliding doors residing in parallel planes when one of the sliding doors is in an open position; one or more slider guides being positioned on the frame of each sliding door to aid in preventing the pins of one of the sliding doors being opened from entering the respective seating grooves in which the pins of the other closed sliding door still reside. 12. The door system according to claim 11, wherein each of the sliding doors comprises a window to permit an interior portion of the refrigeration unit to be viewed. 13. The door system according to claim 11, wherein the one or more slider guides position on a top surface of the inner side of the frame, the one or more slider guides serving as support for the other sliding door when the other sliding door is in an open position. 14. The door system according to claim 11, wherein each of the sliding doors comprises a handle disposed on an upper surface of the outer side of the door. 15. The door system according to claim 11, wherein each of the seating grooves in each of the rails is slanted toward a center of the rails. 16. The door system according to claim 15, wherein two of the seating grooves are on one side of the center of the respective rail and two of the seating grooves are on an opposite side of the center of the respective rail with each of the seating grooves slanted toward a center of the respective rail. 17. The door system according to claim 15, wherein each rail comprises two rail end pieces with each rail end piece having a slanted seating groove therein with the slanted seating groove slanted toward the center of the respective rail. 18. The door system according to claim 17, wherein each rail comprises a rail center piece that has two seating grooves slanted toward each other, the placement of the rail center piece within the respective rail aligns the slanted seating grooves within the rail center piece so that the slanted seating groove are slanted toward the center of the respective rail. 19.
