Electronic dry coolers and condensers fan speed regulators

Electronic dry coolers and condensers fan speed regulators

Purpose

The fan speed controller maintains the condensing pressure for fan-type condensers or fluid outlet temperatures for dry coolers, within prefixed values, for any given load on the unit, reducing power consumption and noise levels of the fan motors. The fan speed controller automatically varies the fan motor speed by changing the input voltage to the motors controlled by discharge pressure which is sensed by a pressure sensor (for air cooled condensers) or by fluid outlet temperature which is sensed by a temperature sensor (for dry coolers).

Features Electronic dry coolers and condensers fan speed regulators

SP-SCU

Single-phase fan speed controllers based on cut phase principle suitable for low and medium capacity units.

AURT

Electronic fan speed controllers based on the cut phase principle suitable for effective and precise control of medium and high capacity units. They can be coupled with the QE control panel.

ARUS

Electronic fan speed controllers using technology based on voltage steps for a regulation completely free from noise, electric and electromagnetic interference. They find their best application where a very precise noise control is needed in particular for high capacity units and can be coupled with the QE control panel.
