* 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
