Cooling Units from Rittal

May 7, 2024

Rittal offers both roof- and wall-mounted air conditioning cooling units suited for applications requiring cooling outputs ranging from 0.50 to 4.00 kW. The cooling units are available in Stainless Steel, Sheet Steel, and Outdoor options. The outdoor option can withstand temperatures up to 140 °. The Blue e+ series includes revolutionary energy efficiency through innovative hybrid technology that averages a 75% savings on energy efficiency due to speed-regulated components and heat pipe technology.

5 Benefits of the Blue e+ Over Traditional Enclosure Cooling Systems

The integral heat pipe provides passive climatization, while active climatization is achieved via the compressor’s cooling circuit with speed-controlled components for demand-based cooling. Not only is energy consumption far less than with conventional technology, but the improved cooling leads to a longer service life of the components inside the enclosure and the cooling unit itself.

Energy Efficiency

  • Hybrid technology combines active, compressor-based cooling with a passive-cooling heat pipe.
  • Using both active and passive cooling circuits provides greater energy efficiency and decreased electrical use.


  • Using inverter technology, Blue e+ air conditioners have multi-voltage capability allowing them to work with virtually any standard voltage including 115V, 230V, or 400/460V.
  • The Blue e+ cooling units offer cooling capacities up to 6,000 watts and can be used in environments ranging from -20°C to +60°C.


  • Thermal management protects sensitive components and extends their service life.
  • Blue e+ ensures a more stable, constant temperature compared with traditional cooling systems.


  • A secure and accessible USB interface allows for efficient data gathering on temperature, efficiency, diagnostics and more. The touch-screen display provides all relevant information, with system messages appearing as plain text.
  • Standardized communication interfaces ensure easy integration in production plant’s control systems.

NFC Capabilities

  • IoT-enabled climate control knows current and expected temperatures, adjusting fans and cooling accordingly.
  • Blue e+ modules and adapters enable data from cooling units to be used in IoT environments providing centralized management, custom alerts, and better integration.
