Overview

Williams HO4USSBA Opal 4 Door Underbench Fridge

The Williams HO4USSBA Opal is an Australian-made four-door underbench refrigerator delivering 670 litres of cold storage at worktop height, purpose-built for the demands of busy commercial kitchens. Maintaining a consistent +1°C to +4°C temperature range with a CoolSmart electronic thermostat and fan-assisted cooling, it keeps ingredients at safe serving temperatures throughout the most intense service periods.

Constructed from 304 stainless steel and rated for tropical Climate Class 4 operation up to 43°C ambient, this prep counter fridge is designed to perform in hot kitchen environments without compromise. The unit includes gastronorm pan compatibility on the top surface, self-closing solid doors, and a removable cassette-style forced-air refrigeration system that simplifies routine servicing and maintenance.
