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. The Logicool InRak must have a minimum of 20% glycol as standard.
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
Glycol of an appropriate concentration (1) must be used within the system to ensure adequate freeze protection.
Please ensure that the concentration is capable of protection to at least 3°C lower than ambient.
Water/glycol solution should be constantly circulated through all waterside pipework and coils to avoid static water from
freezing.
Ensure that pumps are started and running even during shut down periods, when the ambient is within 3°C of the
solution freeze point (1) (i.e. if the solution freezes at 0°C, the pump must be operating at 3°C ambient).
Additional trace heating is provided for interconnecting pipework.
(1) Refer to your glycol supplier for details.

2 Way Chilled Water Regulating Valve
The chilled water valve has an indication of ow on the stem. The
actuator is securely attached to the top of the valve so that when
there is a demand for cooling the valve opens allowing water to ow
through the coil. No demand, the water is shut off allowing no water to
enter the coil (0 VDC no demand, 10 VDC 100% demand).
3 Way Chilled Water Regulating Valve
The chilled water valve has an indication of ow on the stem. The
actuator is securely attached to the top of the valve so that when
there is a demand for cooling the valve opens allowing water to ow
through the coil. No demand, the water goes through the bypass (0
VDC no demand, 10 VDC 100% demand).
2 Way PICV Valve
2-way pressure independent control valves, internally mounted 0-10V
DC PICV valves shall be used to compensate for pressure variations,
performing a continual balancing function to maintain system
performance at varying loads.
Bypass Regulating Valve
A bypass regulating valve shall be tted in the bypass leg of the
system to enable constant ow when there is no cooling demand.
This simulates the coil pressure drop ensuring that the water ow rate
does not change irrespective of amount of ow through the chilled
water coil.
This enables ow through each cooling module without the need for a
Cooling Distribution unit (CDU).
Condensate Pumps
The InRak condensate pump shall be a cold water type (cooling only).
The pump shall be able to pump water 10l/hr @15m maximum head.
Pipework Termination
Pipework shall be terminated in either:
• Brazed Pipework
• Threaded Pipework Connection (BSP)
• Flexible Hose Connection
Flexible Hose Connection
A Flexible Hose connection shall be tted to the unit. Length of 1.5 and 3m shall be avaliable. Hose ends can be either
Male or Female.

DC Axial Fan
48V DC Axial Fans
The fan’s small size shall allow for up to eight fans to be tted, which shall deliver
high airow to reach target capacities.
G4 Filtration
Optional pleated disposable lters shall be available in a rigid metal frame
conforming to BS EN 779-G4.
Constant Air Volume
Constant air volume control allows the user to specify through the user menu the
exact air volume requirements as a set point.
The controller with the aid of differential pressure sensors monitors the air volume
and compensates accordingly to achieve the set point. This ensures a smooth
response to changing system pressures.
The controller uses a PID control loop function to modulate the 0-10 VDC signal
to the fans
Constant Aisle Pressure Control
Constant aisle pressure control is a method of maintaining a pressure differential
between the hot and cold aisles by modulating the fan speed of the InRak unit.
A -100 to +100Pa differential pressure sensor is used to monitor the pressure
difference between the aisles (the same sensor can be easily changed to
-50/+50Pa using a jumper connection depending on individual requirements). This
signal is sent back to the InRak unit microprocessor to modulate the fan speed
to maintain a target differential pressure set point of -10Pa (adjustable). The fan
speed modulates to maintain the target differential.
In the event of the differential pressure sensor failing, (open circuit), the unit will
revert to the xed fan speed (as commissioned). The xed fan speed can be
adjusted in the Manufacturer > Parameters > fans menu.
As the pressure difference decreases the fan speed will increase until the
pressure difference reaches the set point again. If the pressure difference was to
increase the fans would lower their speed and decrease the pressure difference
back to the set point.

Introduction
InRak™ 300mm Technical Manual 9439563 V1.1.0_02_2017
Fan Capacity Control
Capacity control will allow the unit to modulate air volume based on demand for unit cooling. The controller will modulate
the chilled water valve alone to try and increase unit cooling performance whilst maintaining the fans at their minimum
speed. However, if the cooling performance is not increased sufciently then the fan speed will increase to further satisfy
demand.
By default, the valve/fan changeover point is set at 50% cooling demand. The fans will therefore stay at minimum speed
until the cooling demand reaches 50% and then start to ramp up to satisfy the cooling demand. As the unit cooling
demand increases the fan speed is modulated to match the required cooling performance. This feature enhances
system energy efciencies, by having only the required fan input power for particular loadings.

UltraCap Controller Backup
The Ultracap module is an external backup device for the controller. The module guarantees temporary power to the
controller in the event of power failures and allows for enough time to keep the controller running with time to change
power supplies. The module is made using Ultracap storage capacitors (EDLC = Electric Double Layer Capacitor),
which are recharged independently by the module.
These ensure reliability in terms of much longer component life than a module made with lead batteries: the life of the
Ultracap module is at least 10 years.

Dual Power Supply
The InRak range shall be designed with dual power supply
capability, so that in the event of a power failure the supply
can be switched from utility to an alternative power
supply (such as second utility or generator).
A dual power supply changeover switch shall be provided
to enable continuous power to the InRak in order to reduce
unit downtime and therefore loss of cooling to a minimum.
For the dual power supply feature to operate effectively the
two incoming power supplies must have the same voltage
and frequency.
During changeover of power there is an interval of .180ms
with no power. The dual power supply option as standard
is offered with a supply priority select switch. This is used
to determine which of the two power supplies will be used
to supply power to the machine, in the case of an electrical
system with a healthy set of both primary and secondary
incoming power supplies.
Retractable Control Panel
To improve the service access to the InRak, a retractable
control panel has been incorporated into the design to allow
service and maintenance engineers easier access to the
panel and the components around it.
