Environmental Considerations
Freeze Protection Airedale recommends the following actions to help protect the unit during low flow and
low ambient temperature operation.
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 subjected to ambient temperatures lower than 0°C

Glycol of an appropriate concentration
(1)
is used within the system to ensure
adequate protection. Please ensure that the concentration is capable of
protection at least 3°K lower than the minimum ambient.

Water / glycol solution is 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°K 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.
