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 Refrigeration GDM-23-HC~TSL01 Description
The True GDM-23-HC~TSL01 one-section glass door merchandiser is hinged on the left, so it opens on the right. Customers can see into the cabinet through its double-paned, thermal-insulated door since it is made of glass. It features a 12-inch-long extruded handle that enables the door to open smoothly. When staff are loading product into the cabinet, cold air is not lost because the door closes on its own. The removable magnetic door gaskets also keep cold air from escaping.
The black laminated vinyl exterior will not peel or chip since it is both durable and permanent, and its coloration hides dents and scratches. A white aluminum liner brightened by LED lights enables customers to see the stored items. Durable and quick cleaning, its stainless steel interior floor features a built-in drain for leaks or spills. The True GDM-23-HC~TSL01 LH one-section glass door merchandiser has high-density, foamed-in-place polyurethane insulation that gives the cabinet structure and keeps cold air inside. To support the unit on uneven floors, its black powder-coated steel frame rail resists corrosion and comes with leg levelers.
Reducing energy use and extending the unit's life, the condensing coil is kept clean using a reverse condensing fan motor. When the compressor is started, the fan operates in reverse for 20 seconds to rid the coil of dirt and debris. Along with this feature, routine preventative maintenance ensures the unit maintains proper product temperatures.
