Example: When the minimum possible brine inlet temperature in a certain
application is –2°C, then the unit freeze up prevention limit temperature MUST be
set to –12°C or lower. Result will be that the brine mixture may NOT freeze above
that temperature. To prevent freezing of the unit, check the type and
concentration of the brine carefully.
