Fan switch cabinet

What to do if too much heat is generated in the control cabinet? Install fans or install air conditioning? Is an additional filter necessary? Where are the differences? We clarify. Prevent excessive temperatures in the control cabinet and protect your sensitive technology from defects and a shortened service life.

With the use of technical devices, heat is always generated. Under normal circumstances this is not a problem. However, the more technology is installed in your control cabinet, the more likely it is that the temperature will rise above a critical value. When heat builds up in that small space, it's time to take countermeasures. With the eibabo® control cabinet fans, you ensure a better climate and protect your sensitive electronics from damage caused by overheating. The fans of the individual fans are designed and dimensioned differently depending on the model. This means that you too will find the best solution for optimal convection in the control cabinet.

Position devices correctly in the control cabinet

It would be best if you didn't need separate cooling or ventilation for your control cabinet. Additional cooling and ventilation of the cabinet body always poses several challenges.

  • You need a device.
  • The device must be assembled.
  • A power supply must be established.
  • Regular maintenance should also take place.

 

However, improving the natural flow of air is often enough to solve some problems. The first and perhaps most important step is to correctly position the components in the control cabinet. Devices that emit a lot of heat should not be placed close together. The wiring must also be laid properly so that the air has the opportunity to circulate. In order to increase the natural flow of air, there should be ventilation openings with grilles and filters in the upper area of the control cabinet. As soon as a natural air flow is possible, the warm air circulates and rises more easily. In many cases, this already improves the control cabinet climate. If this is still not enough to noticeably reduce the temperature, installing a fan or fans can be very effective. You have already created the conditions for the best possible air circulation by optimizing the device positions.

Does it really make sense to buy a fan for the control cabinet?

Installing air handling units for switch cabinets may seem like another unnecessary expense. Compared to the value of the devices in the control cabinet, however, these costs can be neglected even for high-quality fans. However, if this is omitted or the wrong fan is selected, the entire control cabinet can overheat. This not only jeopardizes the value of the devices contained therein, but also the actual function of the system. This can be the power supply for an entire process flow in a factory or the provision of the computer network within a data center. The consequences of such a failure have far-reaching consequences. Therefore, the installation of a comparatively inexpensive ventilation system makes sense in any case.

 


TIP:

Overheating of expensive devices due to the lack of active ventilation is one of the main reasons for their failure. Effective ventilation extends the service life and significantly increases the energy efficiency of the devices.


 

A simple solution for good ventilation of the control cabinet is a combination of ventilation device and filter unit. In complex systems, ventilation systems are already part of the standard equipment of a control cabinet and are an essential part of the system design. If you would also like to increase reliability, simply take a look around in this catalogue. You will find the right fans and filters for almost every requirement.

How do I choose the right fan for my control cabinet?

When choosing the right ventilation system, you should consider a few things. Ventilation is basically intended to cool the devices in the control cabinet, not to heat them. Yes, even cold and frost damage the technology. So if you have a problem with temperatures that are too low or condensate for certain reasons, air conditioning units or heaters for control cabinets are more suitable for you.

In order to ensure optimal ventilation and a long service life for the devices installed in the cabinet, the dimension and capacity of the ventilation devices must be calculated and selected correctly. The calculations themselves can be done expensively using manufacturer software, or quite easily done manually. For this you need:

  • the difference between the maximum ambient temperature outside the control cabinet and the maximum permissible temperature inside the control cabinet
  • the heat loss behavior of the devices installed in the control cabinet in watts

 

On the Internet you will find tables and diagrams in which you can read off the required ventilation performance (air volume in m³) based on these two values. Please note that this is a simplified calculation. Other conditions not considered here are:

  • the size of the closet
  • the size and position of the openings for supply air and exhaust air
  • the cabinet material, installation conditions or installation environment and its insulation
  • the atmospheric pressure
  • the type of installation of ventilation

 

High quality fans should have ball bearings. Also note how easy it is to dismantle the filter material on the ventilation grille. The cover should be easily removable to access the filter media. With a classic ventilation system, the fan first sucks the air through the air slots and then through a filter into the housing. The warm air exits through another filter mesh, which should be at least the same size as the intake. If necessary, this can also be larger in order to improve the flow behavior. Control cabinet fans must provide adequate protection against dust and splash water in order not to reduce the degree of protection of the control cabinet. Therefore, when buying, pay attention to the relevant information from the manufacturer, the presence of seals and the shape of the slats.

Notice

If the required air exchange cannot be achieved by the built-in fans and filters, there is a wide range of additional axial fans and centrifugal fans to choose from. If required, you will also find powerful air conditioning units for control cabinets here in the shop.


Axial fans are typically used as exhaust fans to extract heated air from the system. When equipment is tightly housed in an enclosure, even exhaust fans may not suffice. In such cases, centrifugal fans are often used to blow cold air into the enclosure from the surrounding space, usually from the bottom of the cabinet.

How and where are control cabinet fans installed?

Control cabinet fans are usually used in the lower area of the control cabinet. Depending on how the cabinet is fixed (wall mounting, built-in, free-standing), choose a suitable position in a side wall, at the back or in the door. Since warm air rises, the exhaust air grille with filter is also installed on the top of the control cabinet. If you decide to use a duct in the ceiling of the cabinet, please consider the risk of inflowing liquids.

Under what circumstances should I better choose an air conditioner?

There are conditions in which a classic ventilation system is no longer sufficient. If, for example, the air temperature outside the cabinet is too high or the quality of the air is too bad, an enclosure air conditioning system can be an alternative. These are designed in such a way that excess heat from control cabinets and device housings is dissipated to the environment. Use a control cabinet air conditioning system if:

  • the ambient air contains too much humidity
  • the temperature inside the housing must be equal to or lower than the ambient temperature
  • the ambient air is very polluted
  • the required heat dissipation cannot be provided by the environment
