APPLICATIONS DESIGN
  • The air curtains are designed to prevent the cold or hot air streams from outside into door openings or gateways.
  • The height or width of the covered areas ranges from 2 to 5 meters.
  • The air curtains are suitable for crowded premises with increased traffic load.
  • Designed for application in manufacturing premises, stocks, garages, car service centers and car wash shops, shopping malls, super- and hypermarkets, conference and exhibition halls, and other premises.
  • Air curtains are available in 4 standard sizes depending on the capacity.
  • The curtains and their components are made of galvanized steel.
  • Rectangular duct high pressure fan serves for air supply.
  • G4 panel filter provides air filtration.
  • Air heating is effected by means of water heating coils or electrical heater.
  • If water serve as a heat medium these curtain types are suitable for the premises with the indoor temperature not below 0оС only.
  • Air distribution is performed through the slit sections.
  • The standard slit sections are 1 to 1.5 m long that enables easy selection for any door opening.
OPERATING LOGIC OF THE AIR CURTAIN
  • Rectangular duct high pressure fan is applied in air curtain.
  • The supply air is filtered and then supplied to the premise through a narrow slit which ensures the outlet air speed increase and its correct operation.
  • If the curtain has a water or electrical heater the supplied air is warmed up to the set temperature.
  • The aerodynamic barrier created in such a way separates the premise from environment.

FAN MOTOR

MOUNTING
  • The impellers with forward-curved blades made of galvanized steel are powered by four- or six-pole asynchronous motors with external rotor.
  • The fans with such turbine modification are featured with relatively high pressure differential and high air flow capacity.
  • For thermal overheating protection the thermal contacts with the leaded terminals are built in the motor winding for connection to the external protection devices.
  • Both horizontal and vertical mounting is possible.
  • In case of horizontal mounting the air curtain is fixed above the door opening and creates the air stream vertically downwards along the whole opening width.
  • In case of vertical mounting the curtain is fixed at one side or at both sides of the opening and the air is streamed horizontally.
  • One vertical curtain covers 10 to 12 m2 space and for larger surfaces the air curtains at both sides shall be installed to increase the effective area.

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.
