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-23F-HST-HC~TSL01 Description
The True GDM-23F-HST-HC~TSL01 one-section display freezer has a black powder-coated exterior made of cold-rolled steel. Its interior is lined with white aluminum and has a stainless steel floor. To keep temperatures at -10 degrees Fahrenheit, this unit uses R290 hydrocarbon refrigerant and is foamed with polyurethane insulation. Its door is made of triple-pane, thermal-insulated glass and closes by itself. Opening from the left, this door features hinges on its right, opposite a 12-inch-long door handle that supplies a comfortable grip. Magnetic gaskets snap into the door frame for an airtight seal.
This freezer display case has four PVC-coated wire shelves that can be adjusted in 1⁄2-inch increments to accommodate most products. LED lighting brightens the interior, and an illuminated exterior sign panel attracts customers. If internal temperatures drop below 0 degrees Fahrenheit for longer than 30 minutes, the door locks and an alarm notifies the staff. A backup battery power supply keeps the door locked if power is cut off from the unit.
Since the True GDM-23F-HST-HC~TSL01 freezer merchandiser has a bottom-mounted condenser, it can be serviced with little difficulty. Its capillary tube system is self-contained, so it does not need extra external tubing, and its condenser and evaporator fan motors are electronically commutated to consistently move air. This unit has an automatic defrost system that starts at a set time and stops when a certain temperature on the evaporator coils is reached. These coils are coated with epoxy to resist corrosion.
