🧪 Anti-Freeze Protection (Inhibited Propylene Glycol PG30, Freeze Protection -25°C)

Split CDU Outdoor Glycol Anti-Freeze Calculator

Size inhibited propylene glycol (PG30) and ethylene glycol concentrations for outdoor rooftop dry cooler loops: provide burst protection down to $-25^circ ext{C}$ while balancing specific heat capacity ($C_p$) and viscosity penalty on heat rejection performance, and winter freeze protection yields.
