The NAISIDA team provides services for the constant temperature and humidity control project of the Shunde Wusha thermoelectric data computer room. The electrical equipment in the central computer room requires the humidity of the working environment to be controlled at about 45%-55%RH, and the temperature is lower than 28℃. When the humidity exceeds 28°C and 65% or more, the high temperature and humid air will cause different degrees of damage and aging to the electrical equipment in the computer room. Using a Nysda dehumidifier to control the humidity in the computer room can ensure that the switches, servers, Routers and other equipment are operating and safe.
