the MG microprocessor control instrument and fixed displacement scroll compressors
or digital scroll compressors. The standard fluid operating temperature range for this
chiller is 20°F to 60°F for units using R410A refrigerant. Units using other refrigerants
have different standard operating ranges. Units operating below 48°F fluid require the
use of a water/propylene glycol to prevent freezing. Customized units may have different
operating ranges. Consult the factory if you have questions about the operating range of
your chiller.
