Data Sheet
Fan speed controller
Type XGE
Used in refrigeration and air conditioning units
Fan speed controller XGE stabilizes condensing
pressure by changing condenser’s fan speed.
The controller reduces fan noise and saves
energy in low ambient conditions.
Widespread usage in refrigeration and air
conditioning units.
Extensive performance testing under dierent
conditions and strict quality control procedures
ensure trouble free operation for many years.
Compact size, reduced weight and high degree
of protection means that it can be mounted
directly on refrigeration lines. Panel mounting
also possible.
Easy adjusting made by the turn of a setting
screw situated on the top surface. Specially
designed heat dissipation radiator ensures no
overheating and extended lifetime.
XGE-EC version for EC fan motors.
Features
• Wide regulating range
• Compact design
• Male or female pressure connection
• Easy setting and adjusting
• Simple and easy electrical connection

Fan speed controller, Type XGE
Functions
Figure 1: XGE
Figure 2: XGE-EC
Fan speed controller keeps the condensing pressure at a steady level by regulating the speed of the AC/EC fan
motors.When pressure is declining the controller decreases the output voltage changing the speed of AC/EC fan
motor. The proportional band is a non-adjustable pressure dierence between max. and min. pressure where the
regulation occurs.
For min. pressure the controller can either operates with min. speed or completely cuts o the output voltage,
depending on the type of the controller.
XGE saves energy and reduces noise by lowering the fan speed or cutting it o.
