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

chips, etc., stuck to the filter with
