Fan speed controller
Type Saginomiya RGE
Fan speed controller RGE stabilizes condensing
pressure by changing condenser’s fan speed.
Widespread usage in refrigeration and air
conditioning units which are operated
throughout the entire year.
Reliable sensing mechanism using bellows.
Suitable for single phase and 3-phase fan motors.

Technical data
Setting point is increased by turning the range
adjusting screw clockwise. It is decreased by
turning the screw counter clockwise. Adjustment
1
should be within the range indicated for the
setting pointer.
Cut o: Fan motor stops when the pressure

decreases below the value Pmin.
Min. Speed: Fan motor operates at the Minimum

Speed when the pressure decreases below the
value Pmin.

The RGE controls the speed of the condenser fan
6
in refrigeration and air conditioning units that
work all year long.
It keeps the condensing pressure at a steady level
by changing the speed of the fan according to
the required condensing pressure.
