We know that electronic and electrical equipment is installed in the electrical cabinet, in fact, there are working temperature requirements, the general storage temperature can not be lower than minus 25 degrees, the working temperature can not be lower than minus 20 degrees, but now the outdoor temperature in the north is very simple to reach the lower limit of this working temperature, this time the heater will play a role.
Heaters are like home heaters, but heaters in industrial cabinets have higher requirements, such as longer life, more stable function, and temperature control. In the application of strict and high reliability, the requirements for the heater are very high, and you can imagine that if the heater itself has a problem, how to ensure the normal operation of the electrical cabinet and equipment!
Rittal heaters, with Germany quality, small size, long service life, have been used in wind power, telecommunications, outdoor and other strict environments.
Does the heater only need to be used for heating? No, heaters aren't just used to raise the temperature inside the cabinet. It also removes condensation from the cabinet and protects electrical equipment. As we all know, the lower the temperature, the greater the relative humidity in the air, but the relative humidity is large, especially sooner or later when the temperature drops, condensation will occur in the cabinet, if the condensation drops on the electronic components or exposed wires, it will lead to short circuits and electrical incidents. In humid applications, such as wind power, power equipment boxes, communication cabinets, turnstile control cabinets, etc., if there is no heater to prevent condensation, the electric cabinet will stop working if it is slight, and the components in the cabinet will be burned out or the cabinet will explode!
Tips for using heaters:
01. In large cabinets, it is best to install multiple low-power heaters to achieve uniform heat distribution.
02. In order to adjust the temperature of the cabinet, it is advocated to use a digital display or a mechanical thermostat to cooperate with the heater, which can display and adjust the temperature in the cabinet.
03. In order to prevent condensation on components, it is advocated to use humidity regulators for heating conditioning.
04. When using the heater, the sealing and protection of the cabinet needs to be done, imagine the cool breeze blowing in from the outside of the cabinet, how can the heater be effective? It is best to choose a Rittal TS8 cabinet, which can reach IP55 protection level, and it is not easy to get water in the outdoors, let alone shelter from the wind and rain.
