HFC alternative Enclosure Cooling Unit (product not subject to the Fluorocarbon Emission Control Law)
Filter-less Enclosure Cooling Unit (HFC alternative)
ENC-GR-Pro
In addition to HFC alternative and energy-saving, it eliminates the need for regular maintenance of fins and filter, which was required with conventional Enclosure Cooling Unit. This significantly reduces maintenance costs and labor.
Non-drain Enclosure Cooling Unit (HFC alternative)
ENC-GR-LE-eco
Ideal for cooling panel located on mezzanine floors where drainage is difficult to dispose of. Non-drain is achieved even in high temperature and humidity environments.
Non-drain Enclosure cooling unit (HFC alternative)
ENC-GR-eco
HFC alternative and energy-saving design will become standard for panels in the future. Furthermore, it is space-saving and can withstand high temperature environments of up to 55°C, making it suitable for use in a variety of work sites.
Outdoor Enclosure cooling unit (HFC alternative)
ENC-GR-SUS
This Enclosure Cooling Unit an all-stainless steel body, making it durable enough for use in harsh environment such as environment with high water and humidity levels, or outdoors.
Small Enclosure cooling unit (HFC alternative)
ENC-GR
The ultra-compact body means it can be installed anywhere, even in panels in narrow spaces where installation was previously impossible due to space constraints.

Causes of panel problems and the benefits of installing Enclosure Cooling Unit
Causes of panel problems
Panel problems are thought to be primarily caused by heat, dust, and humidity, which can lead to failures and shortened lifespans of electronic devices such as drive control devices and power supply transformers housed inside panel.

What is Enclosure Cooling Unit?
Enclosure cooling unit is a dedicated cooler for panel that can "cool" the inside of the panel to a constant temperature. It is a device that controls the overheating of electronic devices, so it is also called a board cooler or board cooler. The cabinet can be sealed and cooled without bringing in outside air, which also has a "dustproof" effect that prevents dust and oil mist from entering the cabin. In addition, the moisture-containing air in the panel condenses and becomes condensation water and is discharged out of the plate, so it is possible to take measures for "cooling", "dust prevention", and "dehumidification" with one unit.
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
Enclosure Cooling Unit by performing "cooling," "dustproofing," and "dehumidification," it is possible to
• Significantly extend lifespan
• Significantly reduce failure rates
• Increase the operating rate of equipment
This helps prevent equipment failures and abnormal shutdowns, contributing to stable operation of facilities.


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.
