Can precisely control the temperature

Precisely control the temperature of the

Refrigerant-free and environmentally friendly

37 dB (at low load)

This product generates less vibration, dust, and noise due to its lack of

moving parts, such as a compressor.

The noise is kept low by reducing the fan speed in low-load operation.

Customers can reduce the noise by setting the unit to constant fan speed

mode when the noise at high load is concerned.

∗Note that in constant fan speed mode, cooling performance is reduced.

Construction and Principles

Heat dissipation air ﬂow direction

The thermo-con is constructed as shown in Figure 1. The circulating ﬂuid outlet temperature

is controlled precisely by a Peltier element (thermo module) between the heat exchanger

and heat sink which is controlled by supplying DC power supply. The circulating ﬂuid returns

to the tank and is transferred by the pump which is built into the thermo-con, then it goes

through the heat exchangers and temperature sensor and out from the circulating ﬂuid outlet.

The heat dissipation air ﬂow direction is as

shown in Figure 2. Air is taken from the front

of the Thermo-con and discharged from the

rear. Do not cover the inlet and outlet vents.

Integrated with the front panel
