Non-Freon Outdoor Cooler

As advanced communication networks develop, network systems are present everywhere outdoors. The outdoor cubicle model reliably protects the internal equipment even under severe conditions such as sun exposure, wind, rain, and dust. Furthermore, by adopting low-noise sirocco fans proven in building air conditioners and multi-stage control tailored to the air conditioning load, we have achieved the industry’s top-class ultra-low noise level.

High Waterproof Performance

• JIS C 0920 Protection class 4 or higher.
• No harmful water leakage at wind speeds of 20m/s and water flow of 4L/m^2/ min.
• No harmful damage or breakage at wind speeds of 40m/s.

Excellent Environmental Resistance

• The exterior panel uses highly corrosion-resistant hot-dip galvanized steel sheet with a heavy anti-salt damage coating.
• The heat exchanger on the heat dissipation side uses aluminum fins treated for corrosion resistance and further coated with urethane resin. Achieves rust prevention performance of 1000 hours or more in the salt spray test (JIS C 5400).

Features List (Available features vary by model)

Maintenance Notification Function	Refrigerant Pressure Abnormality Alarm	Temperature Sensor Abnormality Alarm	Panel Internal Temperature Abnormality Display
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.	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.	An abnormality is displayed if the panel internal temperature reaches the set temperature plus 10°C or higher.
Overload Protection Device	Outdoor Specification	Self-Diagnosis Function	Low Noise
If the compressor continues to operate under an overload condition, the protection device automatically stops the compressor.	A cooler for outdoor control panel cooling.	Added more detailed diagnostic functions when an error occurs.	Industry-leading low noise achieved through the adoption of sirocco fans.

Specifications

Note 1: Nominal value when ambient and panel internal temperatures are 35°C. Cooling capacity is based on Technical Document No. 007 of the Industrial Association of Thermal Equipment for Control Panels.
Note 2: Rated sensitivity current 15mA.
The values indicated by / are 50Hz on the left and 60Hz on the right.

Cooling Performance Characteristics Graph

※1 : The cooling capacity changes because the rotation speed of the panel external fan increases or decreases according to the ambient temperature.
※2 : Outside the operating temperature range, the cooling cycle is unstable, and the cooling capacity decreases.
