REMOTE DISPENSING
What IS AN AIR-COOLED DISPENSING SYSTEM?

Below are descriptions for air cooled systems designed to dispense short distances remotely from walk-in style keg coolers. Two types are utilized - double duct, and single duct. In both types of systems, cold air from the walk-in cooler is forced via a blower through the ducts to the dispense tower, and then returned to the cooler. A return is critical as the air must have a continuous cold air path back to cooler. Otherwise the cold air simply would not move.

A walk-in keg cooler that is used for food storage where the door is continuously opened directly impacts the performance of air-cooled systems due to air temperature fluctuations. The double duct air-cooled system cannot be more than 25 feet overall from walk-in to the dispense tower. Single duct no more than 15 feet. Sizing of the blower is determined by the distance from walk-in to dispense tower, and the number of bends in the shaft.

Double Duct Air Cooled System — Dispensing Up To 25 Feet

The double duct air cooled keg beer system is defined as two ducts with a blower for continuous air circulation. One duct is for the cold air supply from the walk-in-cooler to the point of dispense. The second duct is for the cool air to return from the point of dispense back to the walk-in cooler.

Usually, the double duct system is used in conjunction with a shaft box or double pedestal draft beer tower to insure proper return of air to the walk-in cooler.

Single Duct Air Cooled System — Dispensing Up To 15 Feet

Walk-in cooler air is blown through the smaller (inner) duct and returned to the cooler through the larger (outer) duct. Usually, an air separator kit and a baffle plate are required in the draft beer tower to insure proper air circulation. This type of a system is used with a single column beer tower.
