FAQ
Q1: What are the primary advantages of the roof-mounted Blue e+ over side-mounted units?
A: Space Optimization: It completely frees up the side panels of the enclosure, allowing for flush-to-wall or side-by-side baying, which significantly maximizes floor space.
Superior Airflow: Following the principle of "cold air sinks," it blows cold air vertically from the top, ensuring efficient penetration through high-density components like IT servers or compact inverters.
Q2: How is condensate handled? Is there a risk of water dripping into the cabinet?
A: Blue e+ roof-mounted units feature an integrated condensate evaporator that automatically dissipates moisture. Furthermore, the internal structure is engineered with secure drainage paths and seals to ensure that no water reaches electronic components, even in highly humid environments.
Q3: Why choose a roof-mounted cooling unit over a wall-mounted one?
A: Roof mounting is ideal when side-panel space is restricted or when you need to maintain clear aisles. It also allows for efficient top-down airflow within the cabinet.
Q4: Does the 1.3 kW cooling output account for both 50Hz and 60Hz?
A: Yes, it typically provides 1.3 kW at 50Hz and can reach up to 1.4 kW or 1.5 kW at 60Hz, depending on the ambient conditions.
