Standard Features: The refrigeration system of this product comes pre-wired and ready to plug into a 115V/60Hz/1Ph outlet with a NEMA 5-15P plug. It features a full-length air duct system that ensures optimal distribution of cold air. The condenser and evaporator coils have a large capacity and are corrosion-resistant. The system also has a time-initiated and temperature-terminated auto defrost cycle for seamless operation. The fan motors are electronically commutated (ECM), which allows for rapid cooling with less energy consumption. The condensate drain pan is self-maintaining and energy-efficient, requiring no external drains or electric heaters. The condenser fan motor supports compressor ventilation and condenser coil cleaning and has an auto-reverse feature. The refrigeration system uses the environmentally friendly Blizzard R290 refrigerant, which has zero Ozone Depletion Potential (ODP) and a low Global Warming Potential (GWP). The cabinet construction includes four height adjustable screw legs and 2.5" thick high density polyurethane insulation. The interior and exterior are made of heavy-duty white coated steel, and the interior floor is made of stainless steel with rounded corners and a detachable drain plug for easy cleaning. The lighting system consists of shielded LED bar lighting with an on/off switch, providing bright illumination with low heat output. The doors have black PVC frames, high strength die-cast handles, and a self-closing feature with an adjustable torsion system for a secure seal. The double glass panes on the doors reflect UV rays for efficient cooling. The doors also have snap-in magnetic door gaskets for easy cleaning and replacement. The shelving system includes height adjustable stainless steel clips and epoxy coated steel wire shelves with airflow guards. The temperature control is managed by a multi-function digital controller with an easy to read LED display. It also has an audible overheat protection alarm for the compressor and condenser coil. The factory preset temperature is 35°F, but it can be adjusted within a range of 33°F to 54°F. Optional features include additional shelving, swivel casters with locks, height-adjustable and interchangeable legs, and a wine rack (only applicable to certain models).
