Yamato Electric TC-04E Ceiling Mounting Type

Manufacturer: Yamato Electric Co., Ltd.
Model: TC-04E

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.

Features List (Available features vary by model)

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 $10^\circ\text{C}$ 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.
