Williams HB4USSHC Boronia 4 Door Stainless Steel Solid Door

Williams HB4USSHC Boronia 4 Solid Door Underbench Fridge – Stainless Steel

The Williams HB4USSHC Boronia is an Australian-made, self-contained underbench refrigerator offering 760 litres of cold storage across four solid stainless steel doors. Engineered specifically for the demands of busy commercial kitchens, the unit maintains a consistent +1°C to +4°C temperature range even during the continual door opening and closing that accompanies active service and stock replenishment.

Running on environmentally friendly R290 natural refrigerant and rated for a 40°C ambient environment (Climate Class 4 Tropical), the Boronia is designed to perform reliably on the line. The forced-air refrigeration system is housed in a removable cassette for straightforward servicing, while features such as auto defrost with waste heat recovery, front-breathing ventilation, and a CoolSmart electronic controller with digital LED display make this a practical, energy-efficient choice for any high-volume venue.

Key Benefits

• Worktop-height design integrates cold storage directly on the kitchen line without consuming valuable floor space beyond the bench footprint.
• Four-door configuration provides high-capacity access across 760 litres, reducing traffic at each door section during busy service periods.
• Rated for 40°C ambient environments, so performance stays consistent in hot kitchen conditions without compromising food-safe temperatures.
• R290 natural refrigerant delivers lower environmental impact and reduced running costs compared to traditional synthetic refrigerants.
• Removable refrigeration cassette allows the entire refrigeration system to be extracted quickly, minimising downtime during servicing or maintenance.
• Auto defrost using a waste heat recovery vaporiser eliminates manual defrost tasks and improves overall energy efficiency.
• Two adjustable plastic-coated shelves per door section give staff flexibility to accommodate different container sizes and stock layouts.
• Front-breathing ventilation means the unit can be installed flush against walls or adjacent equipment without requiring rear clearance.
• Australian-made construction with 304 stainless steel and anti-corrosive evaporator coil coating supports long-term durability in demanding kitchen environments.
