Standard Features: The refrigeration system of our product includes a full-length air duct system for R290 models. It comes pre-wired and ready to plug, with a 115V/60Hz/1Ph power supply and a NEMA 5-15P plug. The condenser and evaporator coils have a large capacity and are corrosion-resistant. Pressure relief devices allow for easy access to the cabinet interior when reopening doors. The self-maintaining condensate drain pan is energy-efficient and does not require external drains or electric heaters. Freezers have a time-initiated and temperature-terminated auto defrost heater, while refrigerators have air defrost. R404A models have PSC evaporator fan motors, while R290 models have electronically commutated (ECM) fan motors. R404A models have a removable and washable condenser coil air filter, while R290 models do not require one. The high-performance condenser fan motors ensure efficient compressor ventilation. R290 models use auto-reverse condenser fan motors that also support condenser coil cleaning. The condensing unit is side-mounted, self-contained, and retractable. It uses environmentally friendly refrigerants with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). The condensing units are replaceable and do not require on-site brazing. The cabinet construction features a galvanized steel bottom and rear, four swivel casters with locks, and a high-quality stainless steel worktop. The insulation is 2.5" thick high-density polyurethane. The interior and exterior are made of heavy-duty stainless steel with rounded corners for a hazard-free workspace. The lighting is energy-efficient silicone coated and shatter-proof LED lighting that provides bright, high color illumination with low heat output. The doors have high-strength recessed handles, heavy-duty stainless steel interior and exterior, 2.5" thick high-density polyurethane insulation, frame heaters to prevent exterior moisture build-up, pre-installed door locks for security, self-closing with adjustable torsion system for a positive seal, and snap-in magnetic door gaskets for easy cleaning and replacement. The shelving has height-adjustable stainless steel clips and two epoxy coated, steel wire shelves per section. The temperature control is a multi-function digital controller with an easy-to-read LED display. R290 models have an audible overheat protection alarm for the compressor and condenser coil.
