Founded in 1948 by World War II veteran Bob Trulaske, True refrigeration got its start creating bottle coolers out of downtown St. Louis warehouse, but the brand has grown into one of the largest players in the global commercial refrigeration market. Known for reliable and sanitary commercial refrigerators, the family-owned business primarily creates refrigerators out of its O'Fallon, Mo., headquarters.
True GDM-33-HC-LD 39 1/2" GDM Series Two Section Glass Door Merchandiser - (2) Sliding Doors, Black, 115v
True Refrigeration GDM-33-HC-LD Description
The True GDM-33-HC-LD two-section merchandiser features two sliding glass doors, each equipped with double-paned and thermal-insulated glass for enhanced energy efficiency and a 12-inch handle for quick access. Each of the two doors self-close, and each section has four shelves that are adjustable in 1⁄2-inch increments to create a customized storage and display. For each shelf, four chrome-plated clips provide stability, while LED lights enhance visibility.
This unit includes a laminated black vinyl exterior that resists chipping and peeling, along with a white aluminum interior liner and stainless steel floor that are durable. Cold air is retained in the True GDM-33-HC-LD glass door merchandiser with foamed-in-place polyurethane insulation that also gives rigidity to the cabinet. Temperatures are kept between 33 and 38 degrees, with an oversized refrigeration system and capillary tubes that monitor refrigerant flow. This unit's evaporator and condenser fan motors push out a consistent volume of air, so it produces less heat and uses less energy than other options. Operating in reverse for 20 seconds upon compressor start up, this unit has a reverse condensing fan motor. This automatic feature removes dust, debris, and dirt from the condensing coil, extending the unit's lifespan in a high-volume kitchen. To ensure the condensing coil is kept clean, users should perform routine preventative maintenance.
