Blast Refrigeration

Blast Chillers & Shock Freezers

At GH Coastal Cooling Ltd, we design, supply, and maintain high-performance blast chillers and blast freezers engineered for precise food safety and quality preservation. Our systems are built to deliver rapid temperature pull-down, ensuring HACCP compliance and optimal energy efficiency. All units include a 2-year parts warranty.

How Blast Refrigeration Works

Blast Chilling: Reduces cooked food from +70 °C to +3 °C within 90 minutes or less, minimizing bacterial growth.
Blast Freezing: Reduces product temperature from +70 °C to –18 °C within 240 minutes, preserving cell structure and preventing ice crystal damage.
Airflow Technology: High-velocity, evenly distributed cold air maintains uniform product cooling throughout the cabinet or room.
Dual Mode Operation: Many units operate as both a blast chiller and blast freezer at the touch of a control panel.
