1. How much is the temperature in degrees centigrade for the circulating fl uid?
Temperature range which can be set with the thermo-con: 10 to 60 °C
If a lower temperature (down to –20 °C) or higher temperature (up to 90 °C) than this range is necessary, select the
thermo-chiller HRZ series.
2. What kind of the circulating fl uids will be used?
Circulating fl uids that can be used in the thermo-con: Tap water, Ethylene glycol 20 %
When using fl uorinated fl uids, select the water-cooled thermo-con HEC series.
3. How much cooling capacity required?
Allows a safety factor of 20 % over the capacity that is actually required, taking into account the changes in the operating
conditions. If a larger capacity than this thermo-con is necessary, select the Peltier-type thermo-con HEC series (refer to
the following.) or the refrigerated thermo-chiller HRS/HRZ series.
Example 1 When the heat generation amount in the user's equipment is known.
Heat generation amount: 400 W
Cooling capacity = Considering a safety factor of 20 %,
400 W x 1.2 = 480 W
