Why this single door commercial upright freezer earns its place
The KOLDBOX KXF400SS is a single-door upright freezer built for kitchens that need genuine full-height frozen storage but don't have the width or the demand for a double-door unit. At 595mm wide, 640mm deep and 1850mm tall, it fits the same footprint as a standard fridge but delivers a dedicated freezer alongside it.
Gross capacity is 326 litres across 5 fixed position shelves, cooled by a static system and rated Energy Class A at 210 kWh a year — a strong efficiency figure for a full-height single-door freezer, and worth noting against models running Class D or E at this size. Refrigerant is R290, and it runs on a 13amp supply, so it drops in on a standard socket rather than needing dedicated wiring. Climate Class 4 certification means it's built to hold temperature reliably in a working kitchen, not just a cool store.
The cabinet is stainless steel on the exterior with a white, easy-clean ABS interior, and the door is reversible so hinge side can match the kitchen layout. An integrated door lock is fitted as standard, and a replaceable door gasket covers the main wear point over the unit's life. Rear rollers and front feet make positioning and levelling straightforward, and low-impact branding keeps it looking like kitchen equipment rather than a retail display.
