Evaporator Water Flow and Pressure Drop
Evaporator flow rate must fall between the minimum and maximum values shown in the evaporator
pressure drop table on page 12. Varying chilled water flow through the evaporator while the
compressor(s) are operating is not recommended.

Minimum and maximum flows are established to ensure the Delta-T for each unit size falls within the 6 - 16°F range for proper
unit control. Contact factory for unit operation outside of minimum and maximum flows shown.
