The invention provides for a means to improve chilling capacities of draught beer dispense systems. The invention is comprised of a container of eutectic material that is designed to solidify at a temperature that is close to the desired serving temperature of the beverage that is being chilled. Generally beverages are stored in containers that are kept 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 the beverage to the dispensing tap is generally made up of a multi- line insulated construction that contains two central cooling liquid lines that will bring a cold glycol/water mixture, refrigerant or ice water to the tap and back in a closed loop to maintain the beverage's temperature. A eutectic material designed to freeze at a temperature close to the desired temperature of the cooling liquid is placed in the closed loop to as a reserve source of cooling capacity. Eutectic material is set in a tank of coolant and allowed to freeze. The container is made of a configuration and material that enhances heat transfer between the eutectic material and system coolant. The tank plasced in contact with the coolant in it's delivery and return loop. The tank of eutectic material may also be incorporated in a heat exchanger designed to give a final cooling boost to the beverage in close proximity to the dispensing tap. The volume of eutectic material may also be located in the volume of coolant that is part of the refrigerating device that forms the original source of the coolant.
