Overview

Williams LAZ5UC-HC Aztra Hydrocarbon Single Door Undercounter Freezer

The Williams LAZ5UC-HC Aztra is a compact, high-performance undercounter freezer designed for commercial kitchens where space is at a premium. Running on R290 hydrocarbon refrigerant, it delivers reliable freezing across a temperature range of -18°C to -22°C within a 660mm-wide footprint, making it well suited to tight bench runs and prep areas. Built in the UK from 304 stainless steel, it carries a climate class 4 (tropical) rating and a 43°C ambient rating, ensuring consistent performance even in hard-working, high-temperature kitchen environments.

With 131 litres of usable storage and full 1/1 gastronorm compatibility, the LAZ5UC-HC accommodates standard commercial trays and features adjustable 1/1 GN shelving with anti-tilt tray slides and a removable racking system for flexible organisation. Fan-assisted cooling, automatic defrost, front venting, a self-closing door, and a CoolSmart electronic thermostat with a digital LED display combine to minimise operator intervention and keep running costs low. The unit operates on a standard 10-amp supply and is backed by a 24-month warranty.
