Half-door reach-in freezers are cold storage units that can be opened from one or both sides. These units are a convenient way to store and retrieve items, as they are easier to reach than full-sized freezers. Half-door reach-in freezers are made from materials ranging from stainless steel to plastic. Most are made from stainless steel due to its durability and corrosion resistance. The doors are usually made from transparent plastic or glass for easy visibility. Solid doors on reach-in freezers provide excellent protection against heat, cold, dust, and other contaminants. Solid doors usually have a solid metal frame, and the panels are usually high-quality plastic with excellent insulation properties. Some reach-in freezers have glass windows on the door, so you can see the unit's contents, while others have metal or plastic grates that allow you to view the contents but keep heat and cold in the unit. Half-door freezers typically have more insulation than standard models, which makes them the more energy-efficient option.
