This library is particularly suitable for modeling cooling liquids at higher temperatures as it features an extended temperature range compared to the LibSecRef (like e.g. ethylene glycol/water mixtures).
Please note that the COOLPROP library is an open source project and we do not provide any guarantees for this library (particularly regarding correctness, absence of errors, and stability).
