Game-changing technology
Sustainability at every level
This unique hybrid technology boasts average energy savings of 75% over conventional systems. By significantly reducing your carbon footprint, you are one step closer to becoming climate-neutral. With a longer service life for installed components, global usability and digital service offerings, it guarantees sustainability at every level.
Blue e+ for maximum efficiency
How do we define efficiency? Less is more. Blue e+ cooling units are designed to minimise costs and protect the environment.
Revolutionary energy efficiency with innovative hybrid technology.
- Two parallel cooling circuits operating independently or in tandem, depending on the temperature difference.
- Passive climate control: Heat pipe cooling circuit (dissipates heat from the enclosure as soon as the ambient temperature drops below the setpoint).
- Active climate control: Compressor cooling circuit with speed-controlled components for targeted cooling.
Inverter control ensures a constant temperature inside the enclosure to prolong the service life of the components.
This technology has been proven to achieve average energy savings of 75%.

Innovative hybrid technology creates a world-beating carbon footprint, with average energy savings of 75% thanks to speed-controlled components and heat pipe technology. Unique multi-voltage capability for worldwide use. Intuitive operation via touch display. Identical mounting cut-out (external mounting, partial internal mounting or full internal mounting) for four output categories (1.6 kW – 5.8 kW).
Energy-efficient, carbon-cutting wall-mounted cooling units. The Blue e+ chemical version is available in output categories from 1.6 kW to 5.8 kW. A special component coating provides optimum protection in contaminated environments – ideal for applications where sulphuric acid may be present in aerosol form.
Energy-efficient, sustainable wall-mounted Blue e+ outdoor cooling units in output categories from 1.5 kW to 5 kW. The high protection category of IP 56 / UL type 12/3R/4 and a temperature range of -30 °C to +60 °C provides optimum protection in challenging environments. The cooling unit can be mounted in three different ways (external mounting, partial internal mounting and full internal mounting), for example on Toptec project solutions.
Sustainable, flexible and compact: Rittal Blue e+ chillers provide central, cost-effective chilling of cooling water to supply air/water heat exchangers etc. Up to 70% energy savings are achievable thanks to speed-controlled components and inverter technology. International approvals and multi-voltage capability make them suitable for worldwide use. Intuitive operation via touch display and smart communication interfaces ensure user-friendly operation and analysis.
