OTHER FORMULAS FOR SIZING A COOLING UNIT										

		IT IS RECOMMENDED TO SIZE CHILLER SLIGHTLY LARGER THAN LOAD.	
FOR WATER: BTU=DELTA T X GPM X 500											

	EXAMPLE: WATER COMING IN TO UNIT IS 70 DEG F. LEAVING WATER TEMP IS 85 DEG F.										
		FLOW RATE IS 10 GPM. 									
		THE LEAVING WATER TEMP MINUS THE ENTERING WATER TEMP IS THE DELTA T.									
		85 - 70 = 15     15 X 10 X 500 = 75,000 BTU/HR (TO MAINTAIN CURRENT TEMP) 									

FOR OIL THE FORMULAS ARE VERY SIMILAR. IF THE OIL IS DTE 24 OR EQUIVALENT THE FORMULA											
	IS DELTA T X GPM X 243 = BTU/HR.										

	EXAMPLE: OIL IN RESERVOIR IS 120 DEG F. OIL RETURNING TO RESERVOIR IS 140 DEG F. 										
		FLOW RATE IS 18 GPM.								
		140-120 = 20      20 X 18 X 243 = 87,480 BTU/HR (FOR DTE 24)								

IF THE OIL DIFFERS FROM DTE 24, USE BTU = DELTA T X GPM X 500 X SPECIFIC HEAT OF FLUID										

	EXAMPLE: SAE 40 OIL HAS A SPECIFIC HEAT OF .5  									
		RESERVOIR TEMP IS 100 DEG F. RETURN OIL TEMP IS 120 DEG F. OIL FLOW 								
		RATE IS 15 GPM.								
		120 - 100 = 20      20 X 15 X 500 X .5 = 75,000 BTU/HR

	HOW TO USE THIS CHART:										
		CHOOSE THE BTU (IN RED) FROM THE CHART THAT IS EQUAL TO OR GREATER THAN									
		YOUR CALCULATED BTU HEAT LOAD. FOLLOW THE CHART TO THE RIGHT TO DETERMINE									
		THE PROPER CHILLER MODEL AND TONNAGE YOUR SYSTEM REQUIRES.									
	NOTE: MAXIMUM ENTERING FLUID TEMPERATURE IS 140 DEG F.
