    Glycol Mixture

    Hello,

    Typically we recommend 35% which is a 0°F freeze point. In harsher temperatures you can bring your glycol mixture up to 40% but as long as the chiller is always operating and the pump stays running there should not be freezing/slushing of the solution. Keep in mind the more glycol, the more viscosity which decreases the efficiency of the pump as well as the heat transfer from the refrigeration system.
