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, 2.5" thick high density polyurethane insulation, and a heavy-duty black coated steel exterior with a white coated steel interior. The interior floor is made of stainless steel with rounded corners and a detachable drain plug for easy cleaning. The product also features shielded LED bar lighting with an on/off switch for bright, high color illumination at a lower heat output. The doors have black PVC frames, high strength die-cast handles, and a self-closing mechanism with an adjustable torsion system for a positive seal. The double glass panes on the doors reflect UV rays for efficient cooling, and the magnetic door gaskets are snap-in for easy cleaning and replacement. The shelving includes height adjustable stainless steel clips and epoxy coated, steel wire shelves with airflow guards. The temperature control is 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, 5" or 3" swivel casters with locks, height-adjustable and interchangeable legs, and a wine rack (only applicable to certain models).
