Relationship between humidity and equipment:

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 elements of the electrical control cabinet, affecting the use function and service life of the control elements in the electrical cabinet.

Wt-h500 new intelligent anti condensation cooling and dehumidification device is based on thermoelectric refrigeration to cool the water molecules in the air in power high-voltage switchgear and distribution cabinet 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.

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

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

Safe and efficient dehumidification principle:

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

In high humidity environment, water droplets can be precipitated in only tens of seconds. While reducing the humidity in the distribution box, the circuit temperature rise is used to further reduce the relative humidity.

Small volume and various installation methods:

The dehumidification device of high-voltage cabinet has small volume, exquisite appearance and small installation space; It supports a variety of application schemes, is suitable for a variety of installation methods, is convenient for maintenance, is suitable for new installation of various cabinets, and is especially suitable for transformation and installation.
