Operating principle

Fig. 1. Halton Windis DWI, air curtain - Operating principle

Air curtains, distinguished by their unique aerodynamic design, offer a highly efficient solution for separating two temperature zones or two environments. This unique design not only provides effective separation but also contributes significantly to energy conservation, making it a cost-effective choice.

When faced with challenges of natural heat exchange through open doors, air curtains step in as a practical solution. These curtains effectively separate two areas or environments, halting the natural transfer of heat and thereby playing a crucial role in energy conservation.

In principle, an air curtain is a device equipped with a fan and a heat exchanger (water or electrical). It operates by pushing air to the floor in a smooth, laminar flow, creating a 90% air seal. This seal, akin to an invisible waterfall, effectively stops heat transfer, dust, and flying insects, thereby maintaining a controlled indoor environment.
