It is a professional, single-door vertical cabinet fridge for commercial kitchens that need a 523Ltr storage option within the Williams Jade range. It offers an additional upright storage choice within a 727 mm-wide by 837 mm-deep footprint.

It is a silver Williams refrigerator with 1 door, sold as Smart UK SKU FD354 with manufacturer reference HJ500U-SS. These identifiers distinguish the 523Ltr Jade upright cabinet when ordering or arranging product support.

The cabinet has a capacity of 523Ltr and a net volume of 439Ltr. It has 3 shelves, with 2/1 GN compatibility and 6 trayslide positions, helping operators organise large-format chilled ingredients without confusing total cabinet capacity with usable net volume.

The HJ500U refrigerator operates from +1°C to +4°C for positive-temperature food storage. It uses R290 refrigerant with GWP 3, combining the required chilled range with a low-GWP hydrocarbon refrigerant.

Externally, the cabinet measures 1940 mm high, 727 mm wide and 837 mm deep. Its interior measures 1332 mm high, 567 mm wide and 660 mm deep, with a 567 mm door opening. The product weight is 129kg.

The full-length integral handle provides an easy grip, while the door closes automatically after access. A barrel lock supports controlled storage, and the magnetic balloon gasket forms a tight seal around the door to help maintain cabinet conditions.

The cabinet has a food-safe stainless-steel exterior and radiused internal corners that reduce awkward dirt traps and make wiping easier. Its removable racking system can be taken out for access, while anti-tilt trayslides support safer loading and unloading.

It uses 80 mm high-density polyurethane insulation with low GWP and zero ODP. Heavy-duty, non-marking swivel castors make repositioning easier, while brakes allow the cabinet to be secured once it is in its working position.

The cabinet uses a CoolSmart controller with electro-mechanical buttons and an IP55-rated display. This gives operators a durable, straightforward control interface suited to regular use in a busy commercial kitchen.

It is a 262W plug-in appliance for a 230V, 50Hz single-phase supply, with a plug fitted. The appliance also requires a 13A fuse, so the intended connection should be available at the installation position.

The refrigerator has Energy Rating: C, an Energy Efficiency Index of 48.56 and consumption of 1.77kWh per 24 hours, equivalent to 647kWh per year. It is climate class 5, with a 0.99A running current and 63 dBA operating noise.

An air-cooled condensing unit provides cabinet cooling. The HJ500U uses automatic off-cycle defrost, and the resulting water is vaporised using recycled heat from the compressor, reducing the need for routine manual disposal of defrost water.

Allow at least 500 mm above the cabinet for maintenance access and ventilation. Adequate airflow around the refrigeration equipment is important for efficient operation, so the 1940 mm cabinet height should be considered together with this overhead clearance when choosing the installation position.

Williams uses high-performance helium leak testing during production. This process is intended to detect very small leaks in the refrigeration circuit before the cabinet enters service, supporting dependable operation of the R290 cooling system.

The Williams Jade upright refrigerator includes a 2-year parts and labour warranty, giving commercial buyers defined support for covered faults during the warranty period.
