What are the essential things to check out before purchasing a display freezer?
 

Hey folks,
I'm so happy to announce that I've decided to start an Ice Cream Shop in my home town. It's a tempting business for both kids and adults. Thereby, we can get more sales and revenue. But we have to beat many competitors to scoop out our brand in the ice cream business. Having a display freezer is essential to display a variety of Ice Cream. So that customers, especially kids, get attracted when they visit the shop. I've hired a food equipment company to know the price range and features. I need advice from forum members here who have experience in purchasing a commercial display freezer.
