Mixture of propylene glycol (Mpg)
–
Correction factor
If a mixture of propylene 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:
Mpg
0 (pure water)
Mpg 20% (*)
Mpg 30% (*)
Mpg 40% (*)

(*): For mixtures of propylene glycol (Mpg) over 20% or for other types of anti-freeze solutions, please contact the manufacturer,
for further technical checks.
For all of the models in the EKS Business and High Efficiency series, the following tables show the minimum and maximum evaporator water flow
values, to be taken into consideration and evaluated during the sizing of pumps, storage tanks and water circuit. These values must be considered
as operation limits. If the installation or type of use requires working outside these limits, the manufacturer must carry out a technical check to
ensure the correct and efficient working of the chiller.
