Simple operation

Heat source

Temperature sensor

2/004/006

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. For HECR

004/006/008/010, noise is

reduced by suppressing the

number of fan rotations

when the cooling load is

low.

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.

Precisely control the temperature of the circulating fluid by using the Peltier device.

Refrigerant-free and environmentally friendly.

Learning control function (Temperature control by external temperature sensor)

Low vibration, Low noise

Drain pan

Drain pan is equipped to avoid any

risk of ﬂuid leakage over equipment

mounted in a lower rack.

Fluid ﬁll port

Fluid can be supplied

without removing the

product from the rack.

bracket

Floor type is also available. (Option)

The rack mounting brackets and the handles can be removed and

rubber feet can be mounted instead. (Refer to page 19 for details.)

Example of circulating fluid piping

Figure 2

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.

Construction and Principles

Principle of Peltier Device (Thermo-module)

A Peltier device (thermo-module) is a plate

type element, inside which P-type semicon-

ductors and N-type semiconductors are lo-

cated alternately. If direct current is supplied

to the Peltier device (thermo-module), heat is

transferred inside the device, and one face

generates heat and increases temperature

while the other face absorbs heat and de-

creases 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 be-

tween heating and cooling, so temperature

can be controlled very precisely.

Air-cooled

Thermo-con/Rack Mount Type

Series HECR

1. How much is the temperature in degrees centigrade for the circulating ﬂuid?

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.

Thermo-con/Series HEC

High-precision temperature control type for semi-

conductor manufacturing equipment, medical equip-

ment, etc.

For details, refer to the catalogue on www.smc.eu.

Cooling capacity: 140 W to 1200 W



Temperature stability: ±0.01 °C to 0.03 °C

Circulating ﬂuids that can be used in the thermo-con: Tap 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?
