tna energy-efficient fan for Ferguson ener-freeze 3

tna has introduced an energy-efficient fan design for its Ferguson ener-freeze 3 aimed at reducing energy consumption by more than 30%, providing French fry manufacturers with a more cost-effective and sustainable freezing solution. Featuring the latest airflow technology, the cooling and freezing tunnel is able to evenly freeze a variety of potato products in different shapes, including sticks, cubes and wedges. The energy-efficient freezer fan is designed to reduce operating costs and increase production cycles while ensuring a high-quality and uniformly frozen product.

The freezer features centrifugal fans with curved blades to optimise the air flow underneath the belt, resulting in even air velocity over the product for a high heat transfer rate and even fluidisation across the entire width of the belt. As the air speed is near the product’s fluidisation velocity, the appearance of clusters is eliminated and each French fry is frozen individually and quickly.

The specific impeller construction of the product ensures that the fan curve has almost 100% spare static pressure to minimise the effects of production fluctuations and ensure a more stable fan curve over an increased period of time.
