Simple operation
Heat source
Temperature sensor
This function adjusts the fluid temperature
to the set value with an automatic offset
setting. Set the external temperature
sensor at the circulating fluid inlet located
just in front of the heat source, which
allows the Thermo-con to sample the fluid
temperature. This function is effective
when automatically adjusting for heat
exhaust from piping etc.
Less vibration and noise with no moving
parts such as a compressor.
Better space utilization with
reduced height and depth
compared to the current model
(HEC002).
If the external temperature sensor is installed directly on the heat source, the learning control
function may not work property due to large heat volume or large temperature difference. Be sure
to install the sensor at the circulating fluid inlet.
Circulating fluid volume can be checked.
qTurn the power ON.
wPress the SEL key, and adjust the temperature
setting with the keys.
ePress the RET key to complete.
Can precisely control the temperature of a heat source or process fluid.

Principle of Peltier Device (Thermo-module)
Construction and Principles
The Thermo-con is constructed as shown in Figure 1. It interposes
a Peltier device (thermo-module) between the heat exchangers for
the circulating fluid and facility water and controls the DC power
supply to achieve the target outlet temperature of circulating fluid
precisely.
The circulating fluid returns to the tank, and is transferred by the
pump which is built in the Thermo-con, and goes through the heat
exchangers and temperature sensor and out from the circulating
fluid outlet.
Figure 2 shows an example of circulating fluid piping.The circulating
fluid is transferred at a constant temperature by the pump.
A Peltier device (thermo-module) is a plate type
element, inside which P-type semiconductors and
N-type semiconductors are located alternately. If direct
current is supplied to the Peltier device (thermo-mod-
ule), heat is transferred inside the device, and one face
generates heat and increases temperature while the
other face absorbs heat and decreases temperature.
Therefore, changing the direction of the current supplied
to the Peltier device (thermo-module) can achieve
heating and cooling operation. This method has a fast
response and can shift quickly between heating and
cooling, so temperature can be controlled very precisely.

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 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.
3. How much cooling capacity required?
