5.5.2 Corrosion protection
PFANNENBERG recommends that Pfannenberg Protect Glycol is also used as a rust inhibitor.
The percentages of glycol into the mixture is related to the minimum ambient temperature of the chiller (that must
be in line with the minimum working set point of the unit, please see the technical data of the unit):

CAUTION
Malfunction due to glycol concentration
The higher the concentration of glycol the lower the amount of heat rejection you will be able to get out of the
fluid.
CAUTION
Safety issues due to wrong glycol selection
Ethylene glycol (Pfannenberg Protect PP…E) and Propylene glycol (Pfannenberg Protect PP…P) differs for
viscosity and toxicity. Ethylene glycol is less viscous than Propylene one, so it provides a higher efficiency in
heat exchanging, and has better performance at low temperatures. For applications where is necessary to
ensure a non-toxic process, the propylene glycol based fluids are used because of their low toxicity if ingested;
it can be used for example where fluid can enter into accidental contact with beverages, or for industrial
processes for food and beverages processing. In some applications propylene glycol use is mandatory.
