Electronically
Commutated (EC) Fan
Motor
Shall incorporate external EC rotor motor technology to provide highly accurate
discreet speed control. The fans offer maximum air ow performance while keeping
sound levels to a minimum.
Each fan shall incorporate electronically commutated DC motor control using semi-
conductor modules responding to a signal from the Airedale indoor unit.
EC motors are DC motors with integrated AC to DC conversion; this gives the
exibility of connecting to AC mains with the efciency and simple speed control of
a DC motor. The EC fan shall offer signicant power reduction in comparison with
equivalent AC fan at both full and modulated fan speeds. The inbuilt EC fan control
module shall allow for fan speed modulation from 0-100%, the modulating range of a
standard AC fan is typically 40-100% of full fan speed.
Optional Extras – General
Corrosion Resistant Coated
Coils
For aggressive atmospheres a corrosion resistant coating shall be applied to the
aluminium ns.
Shut Off Valves Where unit isolation for easier maintenance is required, shut off valves shall be
supplied loose for on site tment.
Coil Guards Protective mesh guards can be tted to each of the outer coils to protect against
damage.
