Williams Refrigeration has been manufacturing commercial fridges, freezers, and prep counters in the UK for over 40 years. Their equipment sits in thousands of London kitchens — from high-volume restaurant chains to independent bakeries and patisseries. ADK engineers service Williams units across every London borough, and we know the product range, the common faults, and the fastest way to get your kitchen running cold again.

The Williams Product Range

Williams organises their commercial refrigeration into distinct product families, each designed for specific kitchen applications. ADK services and repairs the full range.

Jade Range — Upright Cabinets

The Jade series is Williams’ flagship cabinet line. Single and double-door upright fridges and freezers built for heavy commercial use. Stainless steel construction, forced-air cooling, and digital controllers as standard. The Jade cabinets are reliable, but in busy kitchens they take punishment. Controller boards develop faults after years of exposure to kitchen humidity and heat. Condenser coils block with airborne grease and flour dust, particularly in bakery environments. ADK provides rapid repair and routine maintenance for Jade cabinets across London.

Amber Range — Prep Counters

Williams Amber counters are a staple in commercial kitchens where prep space and refrigerated storage need to share the same footprint. Two-door, three-door, and four-door configurations with refrigerated wells and solid worktops. These units sit low, right in the cooking line, and they suffer from it. Door hinges wear under constant opening and slamming. Gaskets deteriorate faster than on upright units because of proximity to cooking heat. Condensers block quickly in the restricted airflow under counters. ADK sees more hinge and gasket calls on Amber counters than almost any other single product type.

We supply, install, and maintain Williams refrigeration equipment across London — covering South London and North London. Need a new commercial refrigeration installation? Our engineers can specify and fit the right Williams unit for your business.

Garnet Range — Bakery and Blast

The Garnet range covers bakery-specific refrigeration and blast chilling. Bakery retarder-provers, blast chillers, and blast freezers designed for dough handling and pastry production. These are specialist units — faults here shut down production lines. Common issues include probe failures on retarder-provers causing incorrect proving temperatures and humidity faults affecting dough quality. ADK understands bakery production cycles and provides priority service for Garnet equipment breakdowns.

Onyx Range — Under-Counter

Williams Onyx under-counter units fit beneath standard worktops and cooking stations. Compact, efficient, and heavily used in smaller kitchens and bar areas. Like all under-counter refrigeration, ventilation is the key issue. Restricted airflow around the condenser means these units run hotter than they should, and compressor life suffers. ADK’s maintenance programme includes condenser cleaning and airflow checks on every Onyx service visit.

Common Williams Faults We Diagnose and Fix

Patterns emerge when you service hundreds of Williams units. ADK’s engineers know exactly what to look for:

If your Williams system is showing signs of commercial fridge not cooling or walk-in freezer not holding temperature, do not wait for a full breakdown. Our engineers carry genuine Williams parts and can often resolve faults on the first visit.

• Thermostat and controller faults — digital controllers on older Jade and Amber units lose calibration or develop relay failures, causing temperature swings
• Condenser coil blockage — especially severe in bakery environments where flour dust combines with grease to form a solid mat over the condenser
• Door hinge wear on counter units — Amber prep counters take constant abuse; hinges loosen and doors drop, breaking the gasket seal
• Fan motor failure — evaporator and condenser fan motors burn out, usually preceded by bearing noise that kitchen staff may ignore until cooling fails completely
• Gasket deterioration — heat exposure from nearby cooking equipment accelerates gasket aging on counter and under-counter units

Williams vs Foster — ADK’s Perspective

Both Williams and Foster are UK-manufactured, both produce quality commercial refrigeration, and ADK services both brands equally. The differences are subtle but worth noting. Foster has historically dominated the walk-in cold room and upright cabinet market. Williams has carved out a stronger position in prep counters and bakery-specific equipment. The Amber counter range outsells Foster’s equivalent in many London kitchen fitouts, particularly in restaurant chains and QSR operations. Williams also benefits from excellent parts availability through their parent company, the Ali Group — one of the world’s largest foodservice equipment manufacturers. That means fewer delays waiting for parts and faster repair turnaround for ADK’s engineers.

Planned Maintenance for Williams Equipment

Scheduled maintenance is the difference between a Williams unit lasting 8 years and one lasting 15. ADK’s planned maintenance contracts cover condenser cleaning, gasket inspection and replacement, hinge adjustment, temperature calibration, electrical safety testing, and refrigerant system checks. Every visit generates a detailed report — evidence of due diligence for EHO inspections and insurance compliance. We tailor visit frequency to your operation: high-volume kitchens need quarterly visits; lower-use environments can stretch to biannual.
