To determine the chiller power under different cooling conditions, multiply the cooling capacity in the tables
above by the three correction factors indicated in this table F1xF2xF3.
NOTE FOR WATER AND OIL CHILLERS:
Refer to the coolant liquid conditions/water temperature for the delivery and consumption conditions in the
technical chart in the Manual, Part II.
Prevalence of the Standard Pumps
In dual frequency chillers (50-60Hz), the pump is optimised to work at 60Hz. Using them at 50Hz,
the pressure drops about 20%. The prevalence is calculated using water without additives. If the
water has additives, contact Aftersales.
