Electronically Commutated
(EC) Fan Motor
Each 800mm diameter fan incorporates on board electronics with AC/DC
Conversion and inverter driven DC motor control to offer unparalleled high
efficiency levels combined with smooth step-less speed control and
quiet operation.
Sickle blades reduce air turbulence to minimise sound levels and power
consumption whilst maximising performance.
The long bell mouth design provides improved aerodynamics, up to 10% more
air movement, and an extended vertical throw of air to reduce the chance of air
re-circulation. As standard the enclosure is complete with an integral finger
proof grille.
The fans offer maximum airflow performance while keeping sound levels to
a minimum.
A mains EMC filter is fitted when the EC fan option is selected with the unit. The
filter is design for convenient mains connection within the busbar chamber.
Power Factor Correction When applied to the motors of each compressor, the compressor power factor is
controlled to a minimum operating value of 0.95 at the full operating capacity.
This satisfies many supply authorities that may impose surcharges on
equipment with power factor less than 0.95.
Extra Free Cool Additional free cooling is available when a high air volume EC Fan is selected.
This option is only available with the Free cool chiller.
