=====================================
The chemical desiccant is used to remove the moist air in the electronic control cabinet, and Silica Gel is usually used as desiccant. Silica Gel can absorb moisture in the surrounding air, its saturated absorption of 40% of its own weight. When using Silica Gel, the dosage should be sufficient and evenly placed to ensure a uniform low humidity environment inside the electronic control cabinet. In order to prevent the PLC, frequency converter and so on stop running dew, can design special space Convection heater, use its heat to improve the environment temperature, so as to keep a lower relative humidity of the air in the electric control cabinet. Cut off the heater circuit when the PLC electric control system is running. Electric Control Cabinet should have air intake below, above the vent, the vent should be installed with wire mesh to avoid dust and foreign objects into the cabinet, to prevent liquid dripping. The Mesh density of Wire Mesh determines the dust removal effect, the mesh should be smaller to ensure that dust and larger water droplets can not be inhaled into the cabinet. The exhaust fan should be installed on the top of the electric control cabinet, and ensure adequate exhaust pressure to make the air flow smoothly. Heat dissipation design PLC used in the environment temperature tolerance of 0 ~ 45 °C, the general use of electrical room is no problem. PLC is a small calorific device, when applied alone, its natural heat dissipation is not a problem. However, most of the PLC control systems used in the industrial field still have large-capacity contactors, transformers, inverters or other high-power converter devices, which are large heat generating devices. If the heat dissipation of the whole control system is not considered,
