Introduction
Dry Coolers Technical Manual 9308503 V1.8.0_04_2016
Standard Features
Construction Unit cabinets shall be manufactured from galvanised sheet steel coated with epoxy
baked powder paint to provide a durable nish.
Standard unit colour shall be Light Grey (RAL 7035).
Dual position xing legs shall be supplied attached to the unit via captive bolts and
shake proof washers.
Horizontal Air
Discharge
As standard, unit legs are attached and delivered in the horizontal air discharge mode as
are the isolator and fan speed controller.
The legs attached to the top of the unit are for lifting and stacking and shall be removed
and stored safely if not required.
Fan & Motor Assembly
All Models
The external rotor AC motor shall allow the use of a low power output, single phase,
and speed controllable motor to power the fan.
The motor shall have inbuilt thermal overload protection and the assembly shall be
supplied complete with a nger guard for protection.
Shall be available in either horizontal or vertical air discharge orientation, please
specify at order.
Electrical All electrical components shall be rated for all year round outdoor use.
All wiring shall be colour coded and numbered for identication. All units shall be wired
in accordance with current local and European standards.
Main Electric Isolator A weatherproof mains isolator shall be tted to ensure complete unit isolation of the
electrical panel during adjustment and maintenance.
IMPORTANT
IMPORTANT
Only 2 units may be stacked together.
Vertical Air Discharge As standard, unit legs shall be attached and delivered in the horizontal air discharge
mode and shall be repositioned on site to offer vertical air discharge mode, refer to
Dimensions / Weights / Positioning, for details.
To ensure the unit isolator and fan speed controller are in the correct orientation for vertical air
discharge please specify at order.

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 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
Short Case Axial Fans
(SCAF)
Short case axial fans shall be supplied for indoor installations where discharge air
requires to be ducted to an outdoor location. The fans shall meet duty plus nominal
75Pa of external static pressure.
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.

Horizontal Airow
In the case of a unit with a horizontal airow specied, the location shown in gure 1 will be the nal position of the
ambient temperature sensor, tted in house before shipment.

Vertical Airow
For units selected with a vertical airow, the ambient temperature sensor should be mounted where shown in gure 1.
This will be for transport purposes only. Once the unit has been installed the bracket is to be removed from this location
and fastened to the bracket attached to the coil, shown in gures 3-5.

Dimensions/Weights/Positioning
Stacking units Only 2 units may be stacked together. In addition to the standard minimum clearances
around the unit further space is required.
Positioning dry coolers on top of each other can cause the bottom unit to be starved of air.
A= 1.5m (Two stacked units)
B= 0.5m (For single unit)
IMPORTANT
IMPORTANT
Unit diagrams can be supplied on request.The following illustrations show the unit following xing
leg re-orientation, instructions are provided for this at delivery.
The legs attached to the top of the unit are for lifting and stacking and may be removed and stored

Unit Lifting
General • Employ lifting specialists
• Local codes and regulations relating to the lifting of this type of equipment
should be observed
• Each chain/sling must be capable of lifting the whole unit
• Lift the unit slowly and evenly
IMPORTANT
CAUTION
CAUTION
Only use lifting points provided. Do not use 1 chain between 2 lifting points to avoid load shift.
Ensure that chains/slings DO NOT crush the casework, coil or fan assemblies.
If the unit is dropped it should immediately be checked for damage and reported to Airedale.
Airedale will accept no responsibility for mishandling during the positioning of the equipment.
Horizontal Air Discharge The unit is delivered in horizontal air discharge conguration secured to a pallet.
Where possible the unit should be moved with the pallet in place.
Use 4 lifting eyes attached to 4 individual slings/chains (supplied by others) and
attach 2 to each top leg using the holes provided as illustrated.
Vertical Air Discharge The unit is delivered in horizontal air discharge conguration (with the mains isolator
and fan speed controller already congured for vertical air discharge) secured to a
pallet. Where possible the unit should be moved with the pallet in place.
Before lifting into nal position, the unit legs should be re-orientated, refer to
instructions provided at delivery.
Check the unit is as ordered, discrepancies or transit damage should be reported to Airedale
immediately.
Care should be taken to ensure the unit does not sustain damage before it is lifted into nal
position.
Use 4 lifting eyes attached to 4 individual slings/chains (supplied by others)
and attach 1 to the top of each of the 4 corner legs using the holes provided as
illustrated.
