The True TDD-4 90" model is a quality draft beer cooler that uses forced air cooling, which positively guides airflow to evenly cool the contents of the cabinet. This draft beer dispenser can hold up to 4 half barrel kegs in the refrigerated cabinet. Two 3-inch stainless steel, insulated beer columns are affixed to the top center of the unit's counter. Cold air is channelled directly into each column to reduce foaming and maximize draft beer profits. The TDD-4 also has galvanized interior walls and a 300 series stainless steel floor, making it easy to clean. This draft beer cooler from True is heavy duty and will last a long time in your commercial bar.
