Standard Features: Refrigeration System The refrigeration system is designed with front air breathing for flexible installation. R290 models also include a full-length air duct system. The system comes pre-wired and ready to plug into a 115V/60Hz/1Ph power source with a NEMA 5-15P plug. It features a large capacity, corrosion-resistant condenser and evaporator coils. The defrost cycle is time-initiated and temperature-terminated, with a defrost heater included. Pressure relief devices allow for easy access to the cabinet interior when reopening doors. The self-maintaining, energy-efficient condensate drain pan requires no external drains or electric heaters. R404A models use PSC evaporator fan motors, while R290 models use electronically commutated (ECM) fan motors. The high-performance condenser fan motors ensure efficient compressor ventilation. R290 models also have auto-reverse condenser fan motors for condenser coil cleaning. The bottom-mounted, self-contained and retractable condensing unit uses environmentally friendly refrigerants, such as R404A with zero Ozone Depletion Potential (ODP) and R290 with zero ODP and low Global Warming Potential (GWP). The R290 condensing units are replaceable and do not require on-site brazing. Alternative refrigerant options are available upon request. Cabinet Construction The cabinet is constructed with a galvanized steel bottom and rear. It is equipped with four 5" swivel casters, with locks on the front set for stability. The worktop is made of high-quality 16-gauge stainless steel. The cabinet is insulated with 2.5" thick high-density polyurethane insulation. The interior and exterior are made of heavy-duty stainless steel with rounded corners for a safe workspace. Doors The doors feature high-strength recessed handles and are made of heavy-duty stainless steel. They are insulated with 2.5" thick high-density polyurethane insulation. Frame heaters prevent moisture build-up on the exterior. Pre-installed door locks ensure the security of your items. The doors are self-closing with an adjustable torsion system for a tight seal. The snap-in magnetic door gaskets make cleaning and replacement easy. Shelving The shelving includes height-adjustable stainless steel clips. Each section comes with two epoxy-coated, steel wire shelves. Temperature Control The unit is equipped with a multi-function digital controller with an
