6.0 GLYCOL SYSTEMS
6.1 Glycol Concentration
The system must be fi lled with water and the appropriate amount of ethylene or propylene glycol
to protect against winter freezing. To achieve the approximate glycol concentration, it is necessary
to know the total system volume. The total system volume consists of the fl uid cooler volume, the
evaporator unit volume and the volume of the inter-connecting piping.
The following tables can be used for arriving at an approximate system volume. After installation,
the glycol percentage should be checked. The glycol percentage should be checked at regular in-
tervals to ensure against freeze protection.
