1. How much is the temperature in degrees centigrade for the circulating fluid?
Thermo-con/
Series
HEC
For details, refer to
the WEB catalog or the Best Pneumatics No. 7.
±
0.018°F
to
0.054°F
(
±
0.01°C to 0.03°C)
Circulating fluids that can be used in the Thermo-con: Water, Ethylene glycol 20%
When using fluorinated fluids, select the water-cooled Thermo-con HEC series.
2. What kind of the circulating fluids will be used?
Allows a safety factor of 2 0 % 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.
3. How much cooling capacity required?
Guide to Model Selection
Cooling capacity = Considering a safety factor of 20%,
400 W x 1.2 = 480 W
Series
HECR
Model Selection
Air-cooled
Water-cooled
Example 1 When the heat generation amount in the user’s equipment is known.
Heat generation amount: 400 W
Temperature range which can be set with the Thermo-con: 50 to 140°F (10 to 60°C)
If a lower temperature (down to –4 °F [–20°C]) or higher temperature (up to 194°F [90°C]) than this range is necessary, select the
Thermo-chiller HRZ series.
