Note: The minimum and maximum flow rates listed here only represent the span of flows for a group of available evaporator options. Actual
chiller flow rates vary based on specific evaporator configurations. Refer to the application datasheet or nameplate for specific flow limits for
every chiller.
Note: Minimum chilled water flow rate is for full load selections; variable primary flow ratings as low as 50% of the minimum are
permitted. Glycol limits are higher. Contact your Quantech sales representative for ratings and further information.
