Thermaster 7 Tray Blast Chiller D-G7

The Thermaster D-G7 is a 7-tray commercial blast chiller and shock freezer designed for production kitchens, bakeries, caterers and restaurants that need to move cooked food through the danger zone fast. Taking 7 x GN 1/1 trays with a digital core-probe controller and a +70 to -18°C operating envelope, it locks in food safety and quality across every batch.

Why operators choose the D-G7

• Blast chills roughly +90 to +3°C in under 90 minutes — pulls hot food safely through the bacterial danger zone to protect quality.
• Shock freezes down to -18°C — forms fine ice crystals that preserve texture on frozen batches.
• Holds 7 x GN 1/1 trays — matches standard gastronorm production for easy loading and transfer.
• Digital core-probe controller — drives cycles by food core temperature, not guesswork.
• HACCP compliant — supports documented food-safety record keeping.
• Fan-forced evaporator — delivers even, rapid heat pull-down across the chamber.
• Automatic defrost — keeps the evaporator clear for consistent performance.
• 240V single-phase supply — installs without three-phase wiring on most sites.
