Standard Features: The refrigeration system of this product includes a time-initiated and temperature-terminated auto defrost heater. It also has large capacity, corrosion-resistant condenser and evaporator coils. The unit comes pre-wired and ready to plug, with a 115V/60Hz/1Ph power supply. The pressure relief devices allow for smooth access to the cabinet interior when re-opening the doors. The airflow guard ensures optimal circulation of cold air, and the R290 models include a full-length air duct system. The self-maintaining, energy-efficient condensate drain pan requires no external drains or electric heaters. The R404A models have PSC evaporator fan motors, while the R290 models have electronically commutated (ECM) fan motors. The high-performance condenser fan motors ensure efficient compressor ventilation, and the R290 models use auto-reverse condenser fan motors that also support condenser coil cleaning. The bottom-mounted, self-contained, and retractable condensing unit uses environmentally friendly refrigerants with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). The cabinet construction features galvanized steel top, bottom, and rear, with 2.5" thick high-density polyurethane insulation. The deeper cabinet interior provides more storage options. The unit is equipped with six 5" swivel casters with locks on the front set and three front leg stabilizers. The interior and exterior are made of heavy-duty stainless steel with rounded corners for a hazard-free workspace. The lighting system consists of energy-efficient silicone coated and shatter-proof LED lights that provide bright, high color illumination with low heat output. The doors have high-strength, recessed handles and are made of heavy-duty stainless steel. They also have 2.5" thick high-density polyurethane insulation and frame heaters to prevent exterior moisture build-up. The pre-installed door locks ensure the safety of your items. The doors are self-closing with an adjustable torsion system for a positive seal, and the snap-in magnetic door gasket makes cleaning and replacement easy. The shelving system includes height-adjustable stainless steel clips and three epoxy coated, steel wire shelves per section. The temperature control is managed by a multi-function digital controller with an easy-to-read LED display. The factory preset temperature is -4°F, and the temperature setting range is from -10°F to 54°F. The R290 models also include an audible over
