Glycol Mixture Calculator
Freeze Protection
Calculate glycol concentration for desired freeze point
Formula
Glycol Volume = System Volume x Concentration% | Heat Capacity decreases ~0.2% per 1% glycol
Frequently Asked Questions
Propylene vs ethylene glycol?
Propylene glycol is non-toxic and food-safe, used in potable water systems. Ethylene glycol is more efficient but toxic. Use propylene for any system connected to potable water.
How does glycol affect system performance?
Glycol reduces heat transfer capacity by 10-20% depending on concentration. It also increases viscosity, requiring larger pumps. Size the system accordingly.
