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

The Blue e+ is a new generation of cooling units that deliver unparalleled energy efficiency with speed-regulated components and patented heat pipe technology.


  • Standard cut-out sizes in enclosure doors and side panels make installation and service quick and simple.
  • 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.

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.

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.
