Wt-h300 intelligent semiconductor dehumidification device

Various control and power boxes are equipped with various electrical control elements to realize the implementation of various electrical controls and functions. In order to ensure the reliability of the use function and service life of the equipment, the electrical control elements have strict drying requirements. If the humidity is too high, it is easy to produce rust and mold on the electrical control elements, affecting the use function and service life of the electrical control elements.

The condensation dehumidification device of wt-h300 substation is based on thermoelectric refrigeration to cool the water molecules in the air below the dew point temperature to achieve the purpose of dehumidification. Compared with the traditional dehumidification technology, it has the characteristics of small volume, high stability, no refrigerant and desiccant, environment-friendly and so on.

Product advantages:

1. Ultra thin design.

2. Fully hidden design.

3. Strong dehumidification efficiency.

4. Multiple installation methods.

5. Pre condensed water.

6. Semiconductor cooler elements are used for refrigeration and dehumidification, no refrigerant, no compressor, environmental protection and energy saving

7. Optional with RS485 communication and heating output function (option).

8. The control power supply is AC and DC, which is convenient, safe and reliable.

9. When the ambient temperature is low, it will defrost and drain automatically.

Safe and efficient dehumidification principle:

The condensation dehumidification device of small substation cooled by Peltier effect has the advantages of no pollution, simplified structure, stable operation, low noise and no high temperature point, and will not have a negative impact on the surrounding electrical components and cables; High temperature, overload, short circuit and other failure modes of internal devices are non combustible.

In the high humidity environment, the switch cabinet dehumidifier can precipitate water droplets in only tens of seconds. While reducing the humidity, the relative humidity is further reduced by using the circuit temperature rise.

Small volume and various installation methods:

Small size, exquisite appearance and small installation space; The cabinet anti condensation device supports a variety of application schemes, is suitable for a variety of installation methods, is convenient for maintenance, is suitable for the new installation of various cabinets, and is especially suitable for the transformation and installation of condensation dehumidification device in substation.
