Benefits of Blue e+ Outdoor Wall-Mounted Air Conditioner
The Blue e+ Outdoor wall-mounted air conditioner achieves up to 75% energy savings through speed-regulated components and innovative heat pipe technology.
Reliable enclosure cooling helps protect sensitive electrical components from overheating while extending the service life of control cabinets and cooling systems.
A user-friendly touch display and intelligent interfaces enable simple operation, real-time monitoring, and efficient integration into modern industrial automation systems.
How to Choose the Right Blue e+ Outdoor Wall-Mounted Air Conditioner
Choosing the right enclosure air conditioner depends on several factors, including cooling capacity, enclosure size, installation environment, and application requirements.
Cooling Capacity
Select the cooling capacity based on the heat generated by electrical components inside the enclosure. As a general guideline:
For small control cabinets with limited heat generation, a 1.5 kW (5,118 BTU/h) cooling unit is usually sufficient.
For medium-sized electrical enclosures with automation components, a 2–3 kW (6,824–10,236 BTU/h) model provides reliable temperature control.
For large outdoor enclosures with high-power components such as drives and power electronics, a 3–5 kW (10,236–17,061 BTU/h) cooling capacity ensures effective heat dissipation.
Enclosure Size and Installation Space
Consider the enclosure dimensions, available mounting space, and airflow conditions to ensure efficient cooling performance.
Operating Environment
For outdoor applications, evaluate ambient temperature, sunlight exposure, dust, moisture, and other environmental factors to ensure reliable operation.
Application Requirements
Consider the type and quantity of internal components, such as PLCs, frequency converters, power supplies, and other heat-generating devices.
With multiple cooling capacities available from 1.5 to 5 kW (5,118–17,061 BTU/h), the series provides flexible cooling options for different outdoor electrical enclosure applications.
