Thermaster D-G7 7-Tray Blast Chiller & Shock Freezer – 224L, 7 × GN 1/1

The Thermaster D-G7 7-Tray Blast Chiller & Shock Freezer is a professional rapid-cooling solution designed for restaurants, hotels, catering operations, food production facilities and commercial kitchens where food safety, consistency and efficient preparation are priorities. Combining blast chilling and shock freezing in one compact unit, it allows freshly cooked food to be rapidly cooled or frozen before storage, helping improve workflow and reduce food waste.
With capacity for 7 × 1/1 GN pans and a 224L gross volume, the D-G7 provides practical batch-processing capacity for medium to high-volume kitchen operations. It can rapidly reduce the core temperature of 20kg of food from +70°C to +3°C in under 90 minutes, while its shock-freezing cycle can take 16kg from +70°C to -18°C in 240 minutes.
The unit's dedicated blast process is designed to prevent ice crystallisation from forming, allowing faster temperature reduction while helping preserve the food's texture, colour, flavour and overall quality. Rapid cooling also helps reduce the time food spends in temperatures where bacterial growth can occur, supporting safer food-handling procedures.
