New, compact, and precise Danfoss Saginomiya XGE fan speed controllers can be used in the smallest refrigeration units to provide energy-saving and repeatable fan speed control as condensing pressure varies, ensuring stable system operation, says the company. XGE controllers have features that help in installation and setting, with a wiring diagram and a setting aid embossed on the control. They can be installed directly on the refrigerant line or on an accessory mounting bracket.
