Causes of panel problems and the benefits of installing Enclosure Cooling Unit
Causes of panel problems
It is believed that problems with control panels are primarily caused by “heat,” “dust,” and “moisture.” These factors can cause malfunctions or shorten the service life of electronic equipment housed inside the control panel, such as inverters, servo motors, and power transformers.

What is Enclosure Cooling Unit?
Control panel coolers are specialized cooling units designed to “cool” the interior of control panels to a constant temperature. Since they are devices that prevent electronic equipment from overheating, they are also referred to as panel coolers. By separating the airflow inside and outside the cabinet, they can cool the interior without drawing in outside air. As a result, they also provide a “dust-proofing” effect that prevents dust and oil mist from entering the cabinet. Additionally, they offer a “dehumidification” effect, in which moisture-laden air inside the control cabinet condenses and is discharged as condensate outside the cabinet. Thus, a single unit can provide “cooling,” “dust-proofing,” and “dehumidification” all at once.
It protects against heat, dust, and moisture, which are the causes of panel problems, preventing failures and shortened lifespans of electronic devices and contributing to improved equipment uptime.


By Enclosure Cooling Unit to reduce the temperature rise by 20°C, the lifespan of electronic equipment can be increased by more than four times.

It protects the equipment inside the panel from dust, keeps them in good condition, and reduces the risk of burn and failure.

The dehumidifying effect of Enclosure Cooling Unit prevents problems caused by humidity.
Benefits of installing Enclosure Cooling Unit
By providing "cooling," "dust protection," and "dehumidification" with a control panel cooler, the inverters, servo amplifiers, PLCs, and other components inside the panel
・Significantly extend the lifespan
・Significantly reduce the failure rate
・Increase equipment utilization rates
This helps prevent equipment failures and unexpected shutdowns, contributing to the stable operation of the facilities.

Apiste's control panel coolers employ a "mild cooling" method that gradually cools the interior of the panel in response to rising temperatures, rather than cooling it rapidly. This maintains a stable environment inside the panel while minimizing the risk of condensation and sudden drain water buildup caused by overcooling.

Use a Enclosure cooling unit to make the internal board environment the best condition it can be!
Enclosure cooling units protect electronic devices inside panel from heat, dust, and humidity, contributing to the stable operation of production lines. Please check the catalog for the latest lineup, functions, and features.
A quick explanation of the difference between cooling and heat dissipation in heat countermeasures
When it comes to heat management, cooling and heat dissipation are often confused, so it is important to distinguish between them.
• Cooling: Freezing cycle removes heat from inside the panel and forces cool air to cool the inside of the panel. It is also possible to lower the panel internal temperature below the ambient temperature and dehumidify it.
• Heat dissipation: Simply release (transfer) the heat inside the panel to the outside through a fan or heat exchanger.
The panel internal temperature will be higher than the ambient temperature, and it cannot be lowered because there is no cooling effect.
Cooling (e.g., Enclosure Cooling Unit)
Freezing cycle removes heat from inside the panel and forces cold air to cool it down. It is also possible to lower the panel internal temperature below the ambient temperature and dehumidify it.

Heat dissipation (panel fans, etc.)
It simply dissipates (transfers) the heat inside the panel to the outside through a fan or heat exchanger. The panel internal temperature will be higher than the ambient temperature. It does not have a cooling effect, so it cannot be lowered.
