Door count, glass specification and condensation control
The glass door is the part shoppers touch and the part that most often causes complaints, so specify it deliberately. Confirm whether the door is heated or fitted with an anti-condensation arrangement, because a frozen cabinet in a humid store will fog or sweat without it. Ask about the frame material and how the glass is cleaned, since cleaning chemicals and repeated wiping affect the coating over time. Door count follows the range and the aisle: fewer, wider doors expose more cold air each time they open, while more doors hold temperature better during trading but add frame area and reduce the usable width inside. Confirm the hinge side and whether doors self-close. Check the gasket material and how it is replaced, because a tired gasket shows up first as frost along the frame. Door arrangement, glass specification and anti-condensation measures are confirmed per model and per store conditions.
