LH104 cabinet intelligent dehumidifier

LH104 is a new-type intelligent dehumidification device specially developed by our company to address the condensation phenomenon in electrical cabinets. This dehumidification device innovatively employs a micro high-reliability compressor to reduce the absolute humidity in the cabinet space, causing the humid air inside the cabinet to condense into water and discharge directly outside the cabinet. It can also improve the air environment inside the cabinet by connecting various auxiliary devices such as external axial fans, heaters, and backup equipment (e.g., hot air blowers). The device adopts a scientific dehumidification control strategy, which can quickly and effectively reduce the air humidity inside the electrical cabinet, inhibit the generation of condensation, achieve an ideal anti-condensation effect inside the cabinet, and eliminate the safety threats to the insulation of power distribution equipment caused by long-term condensation.
