Yamato Electric KC-04EB Side Mounting Type

Manufacturer: Yamato Electric Co., Ltd.
Model: KC-04EB
Control Panel Cooler – Standard Model
Equipped with the unique, highly efficient, and dirt-resistant “Spine Fin”!
Features
- High efficiency and space-saving achieved through the adoption of the Spine Fin design.
- Features excellent energy-saving performance due to a high COP value (Coefficient of Performance/Energy Efficiency).
- Improved drainage performance through the adoption of a double-drain structure and a float switch (Ceiling mounting models only).
- An operation panel relocation kit is available as an option to enable control panel operation at a remote location.
Principle of Operation
This unit is a cooling device specifically designed for sealed control panels, employing a refrigeration cycle that incorporates a compressor. The internal circulation fan draws the warm air from inside the control panel into the evaporator (cooler) within the unit, and returns it to the control panel as cool air. This process maintains a low temperature inside the control panel, even in locations with high ambient temperatures, without compromising the sealed state, thereby protecting the internal equipment and electronic devices from heat damage.

| Maintenance Notification Function | Refrigerant Pressure Abnormality Alarm | Frost/Freezing Prevention Function | Temperature Sensor Abnormality Alarm |
|---|---|---|---|
| Displays a filter check output signal at set intervals. | If the refrigerant pressure rises due to filter clogging or other issues, the unit stops abnormally and the alarm contact is activated. | Automatically stops to prevent frost growth on the evaporator. | The unit stops and the alarm contact is activated if there is an abnormality in the panel internal temperature sensor or the evaporator temperature sensor. |

| Panel Internal Temperature Abnormality Display | Overload Protection Device | Drain Water Drainage Abnormality Alarm | |
| An abnormality is displayed if the panel internal temperature reaches the set temperature plus 10°C or higher. | If the compressor continues to operate under an overload condition, the protection device automatically stops the compressor. | If drain water stops discharging due to clogging of the drain hose or other issues, an alarm lamp illuminates and cooling operation is stopped. |
