Cooling unit Rittal Blue e 3000 W, steel housing, IP34/IP54, grey
Rittal Blue e is a roof-mounted cooling unit designed for dissipating heat from enclosures and cabinets. It offers energy-efficient cooling across output categories from 500 W to 4,000 W and includes an integrated e-Comfort controller, RiNano coating on the condenser and an electrical condensate evaporation system as standard. The unit is made of steel, finished in grey, and is built to conform to protection classes IP34 and IP54. Physical dimensions are approximately 796 mm wide, 580 mm deep and 470 mm high.
The Blue e range provides efficient thermal management for cabinet installations with low energy consumption and integrated control via the e-Comfort controller. The RiNano coating enhances condenser durability and corrosion resistance, while the built-in electrical condensate evaporation avoids the need for external drain lines. Its roof-mounted design simplifies installation on top of enclosures and helps maintain internal temperatures reliably.
This unit may not be appropriate for spaces requiring cooling capacities outside the 500 W–4,000 W range. It is designed specifically for roof mounting on enclosures; applications that need portable or split-system air conditioning should consider other solutions. Also, if a water drainage connection is preferred instead of electrical condensate evaporation, this design may not meet that requirement.
Install the Blue e unit on the roof of the target enclosure following the manufacturer's mechanical mounting and electrical connection instructions. Configure the integrated e-Comfort controller to the required temperature setpoints and operating parameters. Ensure the electrical condensate evaporation system is powered and that the condenser area is accessible for routine visual inspection and cleaning to maintain heat-transfer efficiency.
For reliable operation, match the unit's cooling capacity to the enclosure's expected heat load, keep the condenser clean, and programme the e-Comfort controller with appropriate setpoints and hysteresis to avoid frequent cycling.
