Air curtain selection procedure

  • Determine the required air curtain orientation (e.g., vertical).
  • Determine the required heating type (W - water type, E - electrical type, N - no heating)
  • The nomographic chart 1 shows the effective reach distance of the curtain (1) (e.g., 3.5 m; for vertical orientation that value is equal to the door opening width). 
  • For the outlet air stream speed from the curtain draw a perpendicular line down to the nomographic chart 2 (e.g., 13.9 m/s).
  • Using the nomographic chart 3 determine the outlet slit of the air curtain (3) (e.g., 2.5 m; for vertical orientation that is equal to the height of the door opening). 
  • The nomographic chart 4 shows the minimum required air capacity (lines 4 and 5, e.g., 4400 m3/h). 
  • The intersection of curves 5 and 6 lies at one of the colour fields of the design  chart 5. The field of the point location detrmines the standard size of the air curtain (e.g., 800х500).
  • Projection of curve along the parable 7 up to the point of intersection with the curve that limits the colour field from above, determines the operating point of the air curtain. The air capacity 4800 m3/h which is somewhat above the minimum required air capacity refers to the effective operating point.
