In control cabinets, depending on the ambient conditions (e. g. heat, cold, air humidity etc.), there may be a tendency to overheat or for mold to form. In such cases the cubicles should be air-conditioned. The following air-conditioning equipment is available for this purpose:

• Filter fans
• Air conditioners/cooling devices
• Heat exchangers
• Heaters/thermostats

When selecting individual air-conditioning components, the ambient temperature, the power losses of the installed devices, the maximum permissible device temperatures and the heat dissipation capacity of the cubicle used are the factors to be considered. In addition, it is necessary to take into account the required degree of protection.
