The Choice of Electric Window Opener

The Choice Of Electric Window Opener

• Automatic window opener (electric window opener) is a kind of automatic window opening/closing equipment, which is a high technology product integrating mechanical transmission and micro in one and is a widely used window opening execution equipment. It can realize the automatic control of window opening/closing. Its appearance has changed the way of opening windows manually in the past, making it an easy thing to open windows in high places.

  
  

Before choosing a window opener, first determine the type of window: is it top-hung? Down-hung? Mid-hung? Skylight? Sliding window? Casement window? Slanted window? Row windows? Or other special windows or devices.

Skylight

It is preferred to use rack and pinion type or push rod type electric window opener, this type of way is mainly most suitable for force in the vertical direction, there is no possibility of bending, strong resistance to wind and rain, and thrust generally do a lot.

Sliding Window

It needs to use a rack and pinion or push rod type electric window opener, this type of way is more suitable for running in a straight line, in closing the window, the window closure sealing degree is good.

Shutter

It is necessary to use a small rack and pinion type or push rod type electric window opener.

Top/Bottom/Hanging Window

You should use the chain type, rack and pinion type can also be used, but the push-pull force of rack and pinion is the largest.

If you design a wide or heavy window

The width of the window is large (more than 1.5m width) or in the opening/closing of the window, the push/pull force required is large (more than 450N), then you should consider using a double push electric window opener, double push with rack and chain double push, that is, a machine with two racks or two chains to push and pull the same large window to ensure the stability of the window opening and The degree of sealing when closing.

Choose the stroke or angle of the window opener

Opening stroke: both the required opening angle into a straight line distance to open the window, only for daily ventilation, the opening angle generally should not be greater than 30 degrees, the stroke in 300-400mm; but there are fire requirements, in the fire signal linkage, to open the window to the maximum angle of 70 degrees in general.

Window opener push-pull force selection

Generally between 200N-1000N, a simple push-pull calculation F = 1/2 (window self-weight) * (open the maximum stroke / window height).   The force of the smallest window opener is 200N, this force can basically meet the general use of windows.

Window opener using the choice of power

Window opener power supply: AC220V, DC24V, etc. General daily ventilation using power AC220V; when there are firefighting requirements, it is necessary to use DC24V power; and communication facilities with D8V.
