The Williams Jade upright refrigerator is intended for professional kitchens that need substantial chilled storage in a narrow cabinet footprint. Its 1-door, 595 mm-wide format suits sites where floor space is limited but an upright fridge with full-size GN compatibility is required.

The HJ300U-SA has a cabinet capacity of 335.5Ltr and a net volume of 244Ltr. Keeping those measured figures separate helps buyers compare the cabinet capacity with the usable chilled-storage volume rather than treating them as interchangeable figures.

The external dimensions are 1956 mm high, 595 mm wide and 684 mm deep. Internally it measures 1315 mm high, 445 mm wide and 477 mm deep. Allow at least 500 mm above the cabinet for maintenance and ventilation, and position it where the refrigeration equipment receives adequate airflow.

The high-temperature HJ300U cabinet operates from +1°C to +4°C and is Climate Class 5. This chilled range is intended for professional upright-refrigerator use, while the cabinet's air-cooled system manages refrigeration performance.

The cabinet has a foodsafe stainless steel exterior, aluminium interior and silver finish. Radiused internal base corners reduce dirt traps and make routine wiping easier, combining a durable commercial outer surface with a practical, easy-clean storage interior.

The refrigerator has 1 self-closing, barrel-locked door with a full-length integral easy-grab handle. A magnetic balloon gasket forms a complete seal around the closed door, supporting secure storage and limiting unnecessary loss of chilled air during service.

The refrigerator has 3 shelves, anti-tilt trayslides and a removable racking system. It supports full-size 1/1 GN storage, allowing operators to organise gastronorm containers while removing the rack assembly when the interior needs more thorough access.

Yes. It stands on heavy-duty, non-marking swivel castors, with brakes to secure the cabinet once positioned. This provides mobility for access and kitchen rearrangement while helping keep the refrigerator stable during normal use.

The cabinet uses precision-injected, high-density 80 mm polyurethane insulation with low GWP and zero ODP. Its CoolSmart controller has electro-mechanical buttons and an IP55-rated display, giving operators a robust control interface suited to a working commercial kitchen.

An air-cooled condensing unit handles refrigeration, while defrost water is vaporised using recycled compressor heat. High-performance helium leak testing is used during manufacture to check refrigerant-circuit integrity, reducing the need for a separate routine defrost-water disposal step.

The refrigerator uses a 230V plug supply and has a wattage of 262W. It uses R290 refrigerant with GWP 3, carries Energy Rating: C and has an energy-efficiency index of 47.7, with consumption figures of 1.32kWh/24hr and 482kWh/annum.

The refrigerator has a product weight of 91kg and includes a 2-year parts and labour warranty. The weight should be considered when planning delivery and positioning, even though the braked castors make later access and movement more manageable.
