Environmental Considerations
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 3K 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 3K 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.
