Commercial Under Counter Fridge Second Hand. This item is from a coffee shop that has closed down in their main counter. This unit has been serviced yearly and has no refrigerant leaks. It has had a controller changed this year due to workers spilling milk into it. The unit fully works at the time this has been given to me.It is a r134a refrigerant unit and the evaporator is in good condition. As seen in the photo their is some slight damage on the one shelf that the unit has.
