Most versions come with solid or glass doors, but some come with both, with the glass doors on top and the solid doors on the bottom half of the unit. In certain circumstances, solid doors are the more energy efficient of the two options, due to better insulation. They’re also the most popular and, in most cases, the least expensive option.
When the door is locked, glass allows access into the reach-in cooler, allowing people to see what’s inside each segment before opening it. If the custom made refrigerator is frequently used, this could save money in the long term by reducing the amount of time the door is left open. It also allows kitchen workers to review stock levels without having to unlock the lock. A glass merchandiser can be used to showcase items to the public and is a great for selling bottles, cans, prepackaged treats, and other grab-and-go goods.
