A
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.
