Introduction
InRak™ Technical Manual 7462807 V1.11.0_04_2016
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. 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.

Refer to your glycol supplier for details.
