Capacity Correction Factors - Ambient Temperature (C1)
Ambient Temperature (degrees Fahrenheit) 77 85 95 105 115* 122*
Correction Factor 1.0 0.9 0.8 0.78 0.72 0.66

Correction Factor 0.38 0.54 0.83 1.0 1.1 1.25
* Applies to models UC-0010 SP - UC-0240 SP

To calculate the capacity of a given process water chiller based on non-standard operating conditions, multiply the standard capacity by the appropriate correction factor(s).
EXAMPLE: Chiller Model:  UC-100 SP  
  Standard Capacity:  4.12 ton  
  Actual Operating Conditions: 85-degrees Fahrenheit ambient temperature C1=0.5
  44-degree water outlet temperature C2=0.83
Adjusted Capacity = 4.1 ton x 0.9 x 0.83 = 3.08 ton    

To choose a process water chiller based on a given capacity at non-standard operating conditions, divide the given capacity by the appropriate correction factor(s).
EXAMPLE: Given Capacity: 7.5 ton  
  Actual Operating Conditions: 77-degrees Fahrenheit ambient temperature C1=1.0
  55-degree water outlet temperature C2 = 1.1
Adjusted Capacity = 7.5 ton/1.0/1.1 = 6.82 ton  
Selected Chiller Mode: UC-0180SP
