The Kelvinator Commercial KCHGM72F display freezer has locks on all three doors to prevent items from being tampered with or stolen. Its refrigeration system is mounted at the bottom for access when maintenance is needed and self-contained for quick installation upon arrival. To maintain a temperature range of -7.6 to -4 degrees Fahrenheit, this unit cools with R290 hydrocarbon—a natural refrigerant that is safe for the environment. The temperature can be adjusted with electronic controls and monitored on an external display. For corrosion resistance, the interior of the Kelvinator Commercial KCHGM72F three-section display freezer is made of white aluminum. The exterior is made of galvanized and black painted steel, providing both strength and a sleek look wherever it's used. To increase impulse purchases, the doors are made of glass for product visibility and the cabinet is brightened by LED lights. The doors self-close to prevent cold air from escaping and the 12 shelves are vinyl coated for protection.
