Introduction
Procedure
When a component part fails, a replacement part should be obtained through our Spares department. If the part is
considered to be under warranty, the following details are required to process this requirement. Full description of part
required, including Airedale’s part number, if known. The original equipment serial number. An appropriate purchase
order number.
A spares order will be raised under our warranty system and the replacement part will be despatched, usually within 24
hours should they be in stock. When replaced, the faulty part must be returned to Airedale with a suitably completed and
securely attached “Faulty Component Return” (FCR) tag. FCR tags are available from Airedale and supplied with each
Warranty order.
On receipt of the faulty part, suitably tagged, Airedale will pass to its Warranty department, where it will be fully
inspected and tested in order to identify the reason for failure, identifying at the same time whether warranty is justied
or not.
On completion of the investigation of the returned part, a full “Report on Goods Returned” will be issued. On occasion
the release of this complete report may be delayed as component manufacturers become involved in the investigation.
When warranty is allowed, a credit against the Warranty invoice will be raised. Should warranty be refused the Warranty
invoice becomes payable on normal terms.

Warranty may be refused for the following reasons:
• Misapplication of product or component
• Incorrect site installation
• Incomplete commissioning documentation
• Inadequate site installation
• Inadequate site maintenance
• Damage caused by mishandling
• Replaced part being returned damaged without explanation
• Unnecessary delays incurred in return of defective component
Returns Analysis
All faulty components returned under warranty are analysed on a monthly basis as a means of verifying component and

Environmental Considerations
Freeze Protection
Airedale recommends the following actions to help protect the unit during low temperature operation. This also includes
the units subject to low ambient temperatures.
Units with supply water temperatures below +5°C
Glycol is recommended when a supply water temperature of +5°C or below is required or when static water can be
exposed to freezing temperatures.
Units subject to ambient temperatures lower than 0°C, a minimum of 1 of the following is required:
1. Glycol of an appropriate concentration
Please ensure that the concentration is capable of protection at least 3°C lower than the minimum operating
ambient.
2. Ensure water / glycol solution is constantly circulated through all waterside pipework and coils to avoid static
water from freezing.
3. Ensure that pumps are started and running even during shut down periods, when the ambient is within 3°C of
the solution freeze point
4. Additional trace heating is provided for interconnecting pipework.
(1) Refer to your glycol supplier for details.
(2) If this option is selected with ooded evaporators, an actuated suction ball valve must be tted to protect the
compressor from liquid migration.
(1)
(i.e. if the solution freezes at 0°C, the pump must be operating at 3°C ambient).
(1)
is used within the system to ensure adequate protection.

Chiller Technical Manual 7525355 V1.1.0_04_2013
TurboChill™ Air Cooled and FreeCool
Refrigerants
The range has been designed and optimised for operation with ozone benign R134a refrigerant.
Construction
The base shall be fabricated from galvanised steel to ensure a rigid, durable, weatherproof construction.
Unit panels shall be manufactured from galvanised sheet steel coated with epoxy baked powder paint to provide a
durable and weatherproof nish.
Standard unit colour shall be Light Grey (RAL 7035).
Free Cooling Operation
The TurboChill Free Cool chiller has been designed to provide the cooling load required whilst optimising energy
efciency at all times and as such will take advantage of free cooling whenever available. If the free cooling available
cannot satisfy the required full cooling load, direct expansion cooling is used to supplement the output.
In high ambients where free cooling is not available the fan speed modulates in the conventional manner to maintain
an optimised head pressure. Free cooling is initiated wherever the outdoor ambient is 2°C less than the return water
temperature.
During concurent cooling mode condensing temperature is constantly monitored and intelligently kept within the
compressor envelope to allow the fans to run as fast as possible and therefore achieve the most free-cooling without
having a negative impact on compressor integrity.
Introduction
In ambients where the free cooling coil is capable of satisfying the full cooling demand, the condenser fans are
modulated to provide the desired duty. The condenser fans are capable of being modulated between 15-100% (EC) or
40% - 100% (AC) of airow to maintain the supply water temperature.
During periods where the condenser fan speed has been reduced to a minimum, the supply water temperature will then
be controlled by the 3 way valve.

CAUTION
* Feature required if unit is to be shut down for winter with water still circulating through unit. Freeze protection.
This is to stop potential liquid migration.
Chiller Technical Manual 7525355 V1.1.0_04_2013
TurboChill™ Air Cooled and FreeCool
Evaporator
Flooded evaporator incorporating an internal round tube heat
exchanger. This heat exchanger is used to further sub-cool
refrigerant leaving the condenser extending the potential cooling
capacity and as a result, efciency of the system. At the same time
suction gas vapour that passes over the heat exchanger within the
shell is superheated to a higher temperature, eliminating the risk of
wet vapour returning to the compressor.
The heat exchanger is insulated with closed cell polyurethane
foam which is to Class O re rating and the material is UV
resistant.
The ooded evaporator results in signicant energy savings in
compressor operation particularly at part load.
Two immersion heater(s) and thermostat protect the evaporator
against freeze up in ambient temperatures down to -20°C. (in
compliance with Airedale freeze protection policy).
Connections for External Trace Heating (240V / 500W available).
Compressors and evaporator shall be mounted on a rigid
galvanised heavy duty sub frame. Fully weatherproofed electrical
panels are situated at one end of the unit.
Introduction
Actuated Suction Ball Valve(s)
To protect the compressors against liquid migration, actuated
suction line ball valves shall be tted. This protects the
compressors when their is no cooling demand by keeping the
refrigerant in the evaporator, even if water is still owing through
the unit.
Economiser Circuit for Increased Part Load Efciency
The addition of an economiser circuit provides increased cooling and enhances EER, in full and part load operation.
Sub cooled liquid is expanded using a dedicated EEV (electronic expansion valve) to medium pressure and passed
through one side of a plate heat exchanger.
Through the other side ows the ‘normal’ pressure liquid.
The result is that the sub cooling of the liquid entering the system EEV is increased, which improves evaporator
performance and at the same time the suction pressure within the compressor body is lifted, improving compressor
efciency.

TurboChill™ Air Cooled and FreeCool
Condenser
Large surface area microchannel coil(s) (ideally positioned to optimise airow and heat transfer) shall be manufactured
a “V-block” arrangement. This “V-block” arrangement has a lower airside pressure drop making the fans run more
efciently. The coils have freeowing liquid drains that enables us to reduce the amount of subcooling done in the coil,
leaving more area for heat eachange.
R134a Leak Detection System
A factory calibrated leak detection system shall be tted as standard to units containing circuits carrying > 300kg / circuit
of refrigerant to comply with F-gas legislation, however the leak detection system can be supplied as an optional extra
with refrigerant charges <300kg.
A dedicated refrigerant sensor shall be tted within each compressor enclosure and will raise an alarm on detection of
refrigerant gas.
Maintainable Dual Pressure Relief Valve
An auto resetting pressure relief valve assembly shall be provided per evaporator circuit, opening on pressure rise
above 10.3 barg. The dual shut-off valve assembly incorporates 2 pressure relief valves which can be individually
shut off via a 3 way valve. This allows the maintenance of individual pressure relief valves without any requirement for
refrigerant evacuation.
In accordance with EN13136:2001, pressure relief valves have been sized to ensure that in the event of re they can
prevent excessive build-up of pressure within the evaporator. EN13136:2001 section 6.2.1 has been used to size valves
accordingly.
Fire is a hazard that these units have not been designed to operate under. However, the inclusion of various safety
devices ensures that any damage due to re is limited via the release of pressure in the form of gas discharge.
Introduction
If concerns of the ability of the pressure relief valve to discharge in the event of a re >107°C exist, then it is the
responsibility of the end user to protect the pressure relief valve assembly from excessive external temperatures.
This must however allow the pressure relief valve to discharge effectively and not act as a ‘choke’ (offer any resistance)
when discharging.

Ultracap Power Backup
The Ultracap module is a standard feature utilising the latest Ultra Capacitor technology in external backup device for
the EVD Evolution drivers and pCO controllers. The module guarantees temporary power to the controller and drivers in
the event of mains power failures. The Ultra Capacitors are used to maintain the controller’s main functions, to close the
electronic valves in the event of mains power failures. This avoids the need to install a solenoid valve in the refrigerant
circuit or use the battery backup module and allows the system to resume control as soon as mains or backup power
returns to the unit.

Fan Motor
Each 800 mm diameter fan incorporates on board
electronics with AC / DC conversion and inverter driven
DC motor control to offer unparalleled high efciency 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 nger proof grille.
The fans offer maximum airow performance while keeping
sound levels to a minimum.
A mains EMC lter is tted when the EC fan option is
selected with the unit. The lter is designed for convenient
mains connection within the bus bar chamber.
Introduction
The in built EC fan control module allows for fan speed modulation from 15-100%, a standard AC fans modulating range
is typically 40-100% of full fan speed.
The EC fan presents superior energy efciency at full and reduced fan speed compared to the equivalent AC fan motor,
offering efciency savings anywhere between 30 to 100% compared with an AC fan.
Fan speeds are factory set depending on sound level variant.
Standard voltage regulated (VR) fan speed controllers offer a linear response. By comparison the EC fan is adjusted on
demand via the unit microprocessor with precision, offering substantial energy savings. The following illustration shows
a comparison of the typical power input required by each method.

TurboChill™ Air Cooled and FreeCool
Temperature Control
The microprocessor controller shall monitor the return and supply temperatures. The supply temperature is used to
calculate the required cooling demand. Further calculations are then made to determine the optimum compressors to be
selected and their individual cooling demands. These calculations ensure the unit efciency is maximised under all load
Introduction
conditions. As standard, the microprocessor controller can provide an innite capacity control between 15% and 100%,
depending on the component selection. Refer to mechanical data tables for unit specic control ranges.
Monitoring
The microprocessor shall also monitor and display the following measured parameters:
• Supply water temperature
• Return water temperature
• Liquid pressure
Alarm Handling
The controller shall log and allow viewing of the last 150 conditions recorded in descending chronological order through
the keypad display.
The following conditions shall be detected, triggering a visual display:
• High compressor discharge temperature (per compressor)
• Low supply temperature
• Phase rotation
• Emergency stop
• Evaporator ow failure
• Low pressure safety switch
• Low suction pressure (per compressor)
• High liquid pressure
• Compressor 1 contactor status
• Compressor 2 contactor status (dependant on model)
• Volt free contact non-critical alarm indication
• Volt free contact critical alarm indication
Chillers
• Suction pressure
• Evaporator differential water pressure
Building Management Systems (BMS)
Sequencing (Master / Slave and Run / Standby) via the Airedale sequence manager.
Please specify at time of enquiry.
Chiller Sequence Manager
For the efcient temperature and capacity operation of multiple units on a single site, the sequence manager will permit
interlinked operation of the complete system thereby providing optimum temperature control and minimum power
consumption.
Up to 6 units can be sequenced.
Included within this package is a site visit by an Airedale Control Specialist to set up multiple unit sequence control.
The chiller sequence manager is supplied as a separate control panel to be mounted remotely in an indoor location,
such as a plant room.
