Description
Glycol freeze protection fluids with built in inhibitors (designed for hydronic heating systems) should be used (do not use car antifreeze).
These products are important in extreme climate applications and also in HeatLink® snow melt installations. A side benefit to these
fluids is the lubrication/coating they provide to mixing valves and pumps.
HeatLink propylene glycol is premixed with molybdate based corrosion inhibitor. A 20% glycol solution will provide the recommended
molybdate concentration of 100-150 ppm. Higher molybdate concentrations are not harmful to the system.
This product has low toxin levels.

HeatLink recommends the use of 30% glycol for protected areas and the
use of 50% glycol for snow melting systems.
Mixing glycol with water alters the physical properties of water in terms
of heat transfer rate and fluid friction head. Aqueous glycol solutions are
of lower thermal conductivity and more viscous than water alone. When
used in hydronic heating, system flow rate and friction head are to be
adjusted accordingly.

Risk Phrases:
May cause slight transient
(temporary) eye irritation.
Repeated exposure to skin may
cause slight flaking, tenderness
and softening.
Énoncés de risque :
Risque d'irritation légère
passagère des yeux. Un contact
répété avec la peau peut
entraîner une légère
desquamation de l’épiderme, de
la sensibilité et du ramollissement.
Precautionary Phrases:
Exercise reasonable care and
caution when storing.
Mesures de précaution :
Faire raisonnablement attention,
une bonne ventilation générale
devrait suffire.
First Aid:
No adverse effects if inhaled or
ingested. If in contact with eyes,
irrigate immediately with water for
at least 5 minutes. If contact with
skin, wash off in flowing water or
shower.
Read the material safety
data sheet before using.
Premiers soins :
Aucun effet nocif suspecté en cas
d’ingestion ou d’inhalation. En cas
d’atteinte des yeux, rincer
immédiatement à grande eau
pendant au moins 5 minutes. En
cas de contact cutané, laver la
partie atteinte à l'eau courante ou
passer sous la douche.

Fig.15 Thermal Conductivities of Aqueous Solutions
of Industrially Inhibited Propylene Glycol
Note regarding aluminum boiler/components:
The propylene glycol with molybdate inhibitor is buffered to a pH of
approximately 9.5, which will cause an increase in aluminum corrosion.
Systems with an aluminum boiler or components will require a non-inhibited
glycol and molybdate blend optimized for aluminum treatment. HeatLink
does not currently offer a glycol or corrosion inhibitor compatible with
aluminum components.
For more information see Technical Bulletin #5 (TB-005).
