Ice banks with DX (direct expansion) coils are commonly used in dairy farms, milk collection points, and beverage processing facilities. Known for easier installation and lower system costs, these units are a practical choice for medium to large-scale refrigeration needs.

The system includes multiple stainless steel coil batteries housed in a large water reservoir. Refrigerant circulates directly through the coils, forming ice on the pipes and cooling the water in the tank. This approach efficiently cools large volumes of water with relatively low energy use.

Built around natural refrigeration principles, these systems are part of Refra’s water-based solutions and are available in Australia through Hussmann.
