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.

±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?
