The invention provides for a means to improve chilling capacities of draught beer dispense systems. This invention is comprised of a refrigeratio n condensing unit and a heat exchanger that is added to existing draft beverag e delivery systems so that coolant in the system may be cooled prior to its return to t he main refrigeration unit. Generally beverages are stored in containers that are ke pt in remote walk-in refrigerators. Drinks may be dispensed at a location several hundred feet away from the storage container. The beverage trunk line used to transport t he beverage to the dispensing tap is generally made up of a multi-line insulate d construction that contains two central cooling liquid lines that will bring a cold glycol/water mixture, or ice water to the tap and back in a closed loop to maintain the beverage's temperature. The refrigeration system that cools the cold glycol/water mixture, or ice water may at times be overburdened due to high ambient temperatures, high inlet beverage temperatures, high demand of beverages or additional beverage cooling heat exchange units added to the system.
