Why this supermarket freezer earns its place
The ST501 is a glass-lid chest freezer built for frozen retail display, letting customers see the product through the lid before they reach in. It holds 430 litres of net volume from a 491-litre gross cabinet, in a white finish with a white painted-steel interior — a straightforward format for merchandising bagged and boxed frozen lines at the point of sale.
It runs -24 to -14 °C through static cooling with a mechanical controller and manual defrost, so build a periodic defrost into your routine to keep it working efficiently. It carries an energy class D rating with an energy efficiency index of 42%, drawing 952.6 kWh a year — about £238 a year at 25p/kWh, depending on your tariff, ambient and lid use. Noise is rated at 45 dB and it is built to climate class 4.
The cabinet measures 1550 × 720 × 878 mm externally and ships packed at 1640 × 750 × 1000 mm, with a gross weight of 88 kg (78 kg net). It runs from a standard 13 A supply at 220-240 V with an input power of 191 W, and uses R290 refrigerant with a 110 g charge.
