Mixture of ethylene glycol (Meg) – Correction factor
If a mixture of ethylene glycol is used instead of pure water, it causes a change in the performance of the unit. Remember that the choice of the
correct percentage of glycol to be used is determined taking into consideration not only the temperature of the chilled fluid, but also the
temperature of the outside air and/or the environment near the water circuit pipes.
For correct data, please use the correction factor indicated in the following table:
Meg 0 (pure water) Meg 20% (*) Meg 30% (*) Meg 40% (*)
Freezing point 0°C -8,9°C -15,8°C -24,8°C
CcCF 1 0,980 0,974 0,965
CcCF: Cooling capacity correction factor
(*): For mixtures of ethylene glycol (Meg) over 20% or for other types of anti-freeze solutions, please contact the manufacturer,
for further technical checks.
