Series HRZ Model Selection HRZ004-H HRZ008-H HRZ002-H HRZ001-H Guide to Model Selection 1. How much is the temperature in degrees centigrade for the circulating fluid? Temperature range which can be set with the Thermo-chiller L : .20°C to 40°C (“L2” (clear water, deionized water specification) can be set 10°C to 40°C.) H : 20°C to 90°C W : .20°C to 90°C (Select “W” only when the temperature ranges of “L” or “H” are not applicable. HRZ010-W2S (clear water, deionized water specification) can be set 10°C to 60°C.) Example) Customer requirement: 50°C ( Temperature range 20°C to 90°C, “H” type will be appropriate.) 2. What kind of the circulating fluids will be used? Relationship between circulating fluid (which can be used with the Thermo-chiller) and temperature .20°C 10°C 20°C 40°C 60°C 90°C Fluorinated fluids: Fluorinert. FC-3283/GALDENR HT135 Fluorinated fluids: Fluorinert. FC-40/GALDENR HT200 60% ethylene glycol aqueous solution Clear water/Deionized water Example) Customer requirement: Fluorinated fluids Based on the results 1. and 2., Cooling capacity relating “Fluorinated fluids” and “Temperature range 20°C to 90°C” is shown on page 1325. [Cooling Capacity Graph] Circulating Fluid: Fluorinated Fluids, Temperature Range: 20 to 90°C 3. What is the kW for the required cooling capacity? . To calculate the cooling capacity, referring to page 1321. Example) Customer requirement: 5 kW Plot the point of intersection between the operating temperature (50°C) and the cooling capacity (5 kW) in the cooling capacity graph. Circulating fluid temperature setting (°C) Cooling capacity (kW) 10 9 8 7 6 4 3 2 1 0 20 30 40 50 60 70 80 90 5 Customer requirement The point plotted in the graph is the requirement from your customer. Select the Thermo-chiller models exceeding this point. In this case, select the HRZ004-H. Fluorinert. is a trademark of 3M. GALDENR is a registered trademark of Solvay Solexis, Inc. 1320
