I used to sell used household appliances, so I can give you some advice. First of all, won’t this refrigerator take up too much space in your coffee shop? You mentioned that your coffee shop is not very big, and this refrigerator has a capacity of about 1,000 liters. There is a website called manualmachine.com where you can find detailed specifications for this model and see if it is right for you. I used to visit this site often to learn more about the equipment I was buying for sale. If you are still going to go and look at it, first ask the seller to turn it on in advance to make sure that it can maintain the temperature you need.
