Standard Features: Refrigeration System The refrigeration system comes pre-wired and ready to plug into a 115V/60Hz/1Ph outlet with a NEMA 5-15P plug. It features a large capacity, corrosion-resistant condenser and evaporator coils. The full-length air duct system and airflow guard ensure optimal circulation of cold air. The system also has a time-initiated and temperature-terminated auto defrost cycle for seamless operation. Pressure relief devices allow for smooth access to the cabinet interior when reopening doors. The system utilizes electronically commutated (ECM) fan motors for rapid cooling with less energy consumption. The self-maintaining, energy-efficient condensate drain pan requires no external drains or electric heaters. The high-performance, auto-reverse condenser fan motor supports compressor ventilation and condenser coil cleaning. Please refer to the owner's manual for full maintenance instructions. The top-mounted, self-contained, and fully detachable Blizzard R290 condensing unit uses environmentally friendly, EPA-compliant R290 refrigerant with zero Ozone Depletion Potential (ODP) and three Global Warming Potential (GWP). The Blizzard R290 unit is easily replaceable and requires no on-site brazing. Cabinet Construction The cabinet is constructed with galvanized steel on the top, bottom, and rear. It is equipped with four 5" swivel casters, with locks on the front set, for easy mobility. The cabinet features 2.5" thick high-density polyurethane insulation. The interior and exterior are made of heavy-duty stainless steel with rounded corners for a hazard-free workspace. Lighting The cabinet is equipped with shielded LED bar lighting, which can be turned on or off using the switch. The LED lighting provides bright, high-color illumination while emitting lower heat output. Doors The doors have matte finish aluminum frames and high-strength, die-cast door handles. Frame heaters prevent exterior moisture build-up. The doors are self-closing with an adjustable torsion system for a positive seal. The low emissivity double glass panes reflect UV rays for efficient cooling. The snap-in magnetic door gaskets make cleaning and replacement an easy process. Pre-installed door locks are included to keep your items safe from theft (excluding models ESGRH2 and ESGRH4). Shelving The shelving includes height-adjustable stainless steel clips. Each section comes with four epoxy-coated, steel wire
