Technical data






 

ELECTRICAL ACTUATORS:
CHAIN AND LINEAR

Chain actuator: for bottom hinged windows (hinges on the bottom side, inside opening); for top hinged windows (hinges on the top side outside opening)

Linear actuator: for louvres, skylights and domes

To calculate the window opening and closing force please refer to the following semplified formulas
remember that 1 N (Newton) is about 0.1 kg (kilograms)

 

ACTUATOR FORCE (F) FOR VERTICAL WINDOWS

F = (WINDOW LEAF WEIGHT /2) X (ACTUATOR STROKE / WINDOW LEAF HEIGHT)


BOTTOM HINGED WINDOW

Force calculation example

WINDOW LEAF WEGHT (P) = 100 kg

ACTUATOR STROKE (C) = 250 mm

WINDOW LEAF HEIGHT (H) = 1000 mm

THE REQUIRED FORCE (F) IS :

F= (P:2)X(C:H)
F= (100 : 2) X (250 : 1000) =
12.5 kg (125 N)


TOP HINGED WINDOW
 
 

ACTUATOR FORCE (F) FOR HORIZONTAL WINDOWS

F = WINDOW LEAF WEIGHT / 2

   
 

SKYLIGHT

Force calculation example

WINDOW LEAF WEIGTH (P) = 100 kg

THE REQUIRED FORCE (F) IS :

F= P: 2
F= 100 : 2 = 50 kg (500 N)
