Dry Coolers Technical Manual 9308503 V2_06_2020
Optional Extras - Energy
Saving
Electronically
Commutated (EC) Fan
Motor
Shall incorporate external EC rotor motor technology to provide highly accurate
discreet speed control. The fans offer maximum air flow 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
flexibility of connecting to AC mains with the efficiency and simple speed control of
a DC motor. The EC fan shall offer significant 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 fins.
Shut Off Valves
Where unit isolation for easier maintenance is required, shut off valves shall be
supplied loose for on site fitment.
Coil Guards
Protective mesh guards can be fitted to each of the outer coils to protect against
damage.
