Williams Opal HO4USSHC / HO4RSS - 4 Door Stainless Steel Undercounter Fridge 2401mm 670L
Spanning 2401mm with four solid doors and 670 litres of 1/1 GN-compatible storage, the Williams Opal HO4USSHC is the biggest fridge in the Opal foodservice counter range and the one to pick when a whole section of the kitchen needs cold storage under one continuous stainless steel bench. It holds +1°C to +4°C in rooms up to 40°C, runs on R290 hydrocarbon refrigerant and is tested at 3.1 kWh per 24 hours. Front breathing means no drain and no side clearance. Choose the self-contained HO4USSHC (10 amp plug) or the HO4RSS remote cabinet, which is 2219mm wide and supplied without a condensing unit for your own refrigeration plant. Designed and built by Williams in Australia.

Good to know before you buy:
- Refrigeration option: the self-contained HO4USSHC is complete and plugs in. The HO4RSS remote is the same cabinet without a condensing unit: your refrigeration mechanic sizes, supplies and installs the condensing unit, pipework and controls (solenoids are not fitted or supplied). Williams can advise on sizing. We supply the equipment only.
- Power: a standard 10 amp outlet for either version.
- Access: this is a 2.4 m long, 190 kg cabinet. It is delivered by tailgate truck to the front of your premises, so measure every doorway, corridor and corner on the way to its final position before you order. Standard delivery does not include carrying it inside.
- Airflow: keep the front grille clear. The self-contained model needs no side or rear clearance.
- Options: drawer sets in place of any door, pass-through doors, cylindrical locks, extra shelves, a stainless rear and underside, or 150mm legs instead of castors. Ask us for a price.
Compare similar models:
- Williams HO4USSBA / HO4RSSBA: the same four-door fridge with a blown-air well for 10 x 1/3 GN pans
- Williams LO4RSS: four-door freezer, remote only
- Williams HO3USSHC / HO3RSS: three doors, 510 litres, 1910mm wide
- Williams Emerald HE3USS / HE3RSS: 800mm deep three-door fridge, 900 litres, 2506mm wide
Common questions:
Does it really plug into a normal power point?
Yes. Even at four doors the self-contained HO4USSHC runs on a 10 amp plug and draws 1.68 A, the same as the two and three-door models, because Williams uses one efficient R290 system for the whole cabinet.
Would the Emerald HE3USS suit me better?
They suit different jobs. The Emerald is 800mm deep and takes 2/1 GN, so it stores more (900 litres) in a shorter 2506mm cabinet, while the Opal is 700mm deep for 1/1 GN and gives you four separate doors.
Do you install it?
We supply the equipment only. The self-contained model plugs into a power point. The remote cabinet must be connected to a condensing unit by a licensed refrigeration mechanic in your area.

Warranty: Williams 24-month parts and labour warranty from the date of invoice on the self-contained HO4USSHC (12 months parts only on the HO4RSS once connected to a remote condensing unit), carried out by Williams authorised service agents on the Australian mainland. Warranty repairs must be logged with Williams first.
