Glass Door Upright Freezers provide ample storage with the added benefit of being able to see the product inside the freezer before opening the door. In a kitchen where the freezer is being constantly open and shut, glass door freezers have the advantage of staff being able to find the food before opening the door, saving on both energy and time. The high quality glass means that the freezer is extremely well insulated and holds temperature more efficiently. Most freezers come with built in LEDs to provide better lighting whilst saving on power. These freezers can also be used in front of house applications, grocery stores and supermarkets for self serve products like frozen foods, ice creams, frozen vegetables etc. All refrigeration products stocked by CFM Online only use government approved, ozone friendly r134a and r404a refrigerants.
