Rittal Blue e+ S Wall-Mounted Cooling Unit 1000 W, SK 3184840, 400 V

Temperature-sensitive controls and drives in enclosures need reliable cooling. The Rittal Blue e+ S SK 3184840 is a wall-mounted cooling unit that delivers 1000 W of cooling capacity while using up to 75% less energy than conventional units. Its hybrid technology combines a heat pipe and compressor to adapt to thermal loads, making it an intelligent choice for energy-conscious operations.

Highlights

• Hybrid Blue e+ technology: heat pipe and compressor work together for efficiency
• Integrated e+ controller with touch display for intuitive operation
• Wide input voltage range (110–240 V) with 50/60 Hz compatibility
• Compact wall-mounted design saves floor space
• IP55 protection for internal circuits, IP34 for external circuits

In daily use

This cooling unit automatically selects the most efficient cooling mode based on the internal temperature. When cooling demand is low, the heat pipe provides passive cooling without compressor operation, reducing energy consumption. The touch display allows easy monitoring and configuration, while interfaces like USB, Ethernet, and CAN bus enable integration into higher-level control systems. The unit is designed for wall mounting in industrial environments and operates reliably in ambient temperatures from -20°C to +60°C.
