Glycol Adding Requirements
Purchase glycol and corrosion inhibitor from a local qualified smart cooling
product installation company.
Determine the glycol volume concentration based on the lowest temperature
in record in the area.
As the glycol solution is toxic, avoid skin contact with the glycol solution and
splashing it into your eyes. Dispose of the glycol solution in accordance with
local laws.
To prevent glycol solution from corroding pipes and the heat exchanging coil,
corrosion inhibitor should be mixed into the glycol solution. For details about
the mixing schemes, consult glycol experts.
Check the quality of the glycol solution on a quarterly basis and evaluate the
anticorrosion effects. For details, consult local water treatment experts.
