Rittal SK Blue e+ 5800W, WALL MOUNTED,380-480 V

The Rittal SK Blue e+ 5.8 kW wall-mounted cooling unit is engineered for high-performance enclosure climate control in demanding industrial environments. Operating on 380–480 V, 3-phase, 50/60 Hz, this model efficiently manages heavy heat loads from power electronics, automation systems, and switchgear cabinets.

Thanks to advanced heat pipe technology and speed-regulated components, the unit can achieve average energy savings of up to 75%. As a result, operating costs are significantly reduced while maintaining reliable cooling performance.

Moreover, the integrated e+ controller continuously adjusts output according to actual cooling demand. Consequently, the system enhances equipment protection, improves energy efficiency, and extends component lifespan.

Available in sheet steel (RAL 7035) and stainless steel versions, the Blue e+ series offers flexibility for various industrial applications.
