Nor-Lake AdvantEDGE NLBB69, 69-inch 2 Solid Door Back Bar Refrigerator W/Free Flowing Air System

Behind every talented bartender is a reliable bar cooler. Bar coolers are the workhorses that work quietly behind the scenes to keep beer, wine, cocktail ingredients and other items chilled at their ideal temperatures.

But how do these coolers work? What should you look for when buying one, and which models are the best?

One of the workhorses of any restaurant is the refrigeration system that restaurant owners put in place. A competent system is integral to the freshness of your food, and customers come in for the freshest food available, so it's worth putting in the investment into commercial refrigerators versus the kind made for the home.
