Air Curtain Selection

Design Considerations

Biddle is part of your team. We work closely with consultants and architects

from the earliest design stages to ensure the optimum air curtain solution is

achieved for both new build and refurbishment projects.

Critical design considerations include:

• Store location, layout and age

• Building leakage characteristics

• Positive/negative pressurisation of the store

• Standard of mechanical air supplies

• Entrance doorway, width and height

• Multiple doors on different elevations

• Employee awareness of the problems caused by leaving bulk store doors

open in foodstores

• Lobbied/no door environment

• Environmental factors - wind data, direction or speed

The selection of an appropriate air curtain depends on:

A. The door height (= mounting height, measured from floor to bottom of unit).

B. The door width (recommended unit overhang - minimum of 100mm each side).

C. The volume and temperature of the outside air entering through the open door.
