Ethanol 26% 23% 18% 13%
Heat Transfer Fluid (HTF) Mix according to manufacturer’s direcons on container label
Note: Anfreeze soluons are shown in pure form - not premixed
HTF is a premixed Methanol Soluon
*Concentraons below 25-30% (consult manufacturer) typically require addional inhibitors.

Notes:
1. Consult with your representave or distributor if you have any quesons regarding anfreeze selecon or use.
2. Some anfreeze suppliers and manufacturers recommend the use of either de-ionized or dislled water with their
products. Some brands are designed to work with tap water. Consult the anfreeze manufacturer’s technical data.
