Williams Refrigeration has released a new versions of its reach in blast chillers and blast chiller/freezers which provide significant improvements over previous models. Blast chilling is a key process for cook chill systems, allowing businesses to safely chill and store food in batches before regeneration is required.

The new models ensure chilling food safety regulations are followed by rapidly chilling food from +90°C through the danger zone where harmful bacteria can grow, to a safe storage temperature.

The range now uses natural hydrocarbon refrigerant which has low Global Warming Potential and zero Ozone Depletion Potential. As the charge is less than 150g it falls beneath the threshold for hydrocarbon equipment, which means there’s no need for costly insurance or zone control and allows it to be installed directly on a cookline.

Chilling and freezing times have been reduced compared to previous models, while a powerful food probe sensor can save energy by stopping the cycle as soon as the food reaches the required temperature. The probe can be stored away helping to avoid damage when not in use. A powerful self-regulating system protects the compressors while cooked food is being loaded by cooling down the system before the program cycle is activated.

While some manufacturers promote a maximum capacity for their blast chiller/freezers, this is often smaller for freezing than it is for chilling. However, Williams blast chillers have the same capacity regardless of whether it is being used to freeze or chill.

The overall design has been improved, with a sleek new door and the popular, easy to use Williams EasyBlast (WEB) controller. A simple 1-2-3 interface makes it easy for staff to program the cycle, while a clear digital display shows the elapsed time and the food probe temperature.

The door can be configured to be either right or left hand hung. A full-length integral door handle provides an easy to use, non-slip grab that is designed to be easy to clean, with no potential dirt traps.

The reduction in chilling and freezing times helps to deliver significant savings in energy compared with previous models. Efficiency is further improved by the 75mm high density polyurethane insulation which helps to maintain operating temperature in ambient conditions up to 43°C.

Williams blast chiller and chiller/freezer ranges are available in both reach in and roll in models in a variety of capacities. Its new range of reach in models are available from the compact 10kg undercounter unit up to 50kg cabinets while roll in models start from 70kg capacity up to 320kg.

Williams Refrigeration offers a comprehensive range of commercial refrigeration including gastronorm cabinets and counters, specialist bakery equipment, coldrooms, multidecks and blast chillers.
