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.

Introduction
InRak™ 300mm Technical Manual 9439563 V1.1.0_02_2017
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.
