Rittal Blue e cabinet cooler 750 W, steel, IP34/IP54, grey

The Rittal Blue e is a roof-mounted, energy-efficient cooling unit designed for enclosure climate control. Available in output categories from 500 W to 4,000 W, it 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 certified to protection classes IP34 and IP54. Its external dimensions are 597 mm (width) × 417 mm (depth) × 380 mm (height).

Advantages

The Blue e combines a compact roof-mount design with energy-efficient operation across a wide range of cooling capacities. The built-in e-Comfort controller simplifies temperature management while the RiNano condenser coating improves corrosion resistance. Electrical condensate evaporation eliminates the need for drain connections, reducing installation complexity.

Suitable for

• Cooling electrical and electronic enclosures in industrial environments
• Roof-mounted installation on control cabinets and small to medium-sized enclosures
• Applications requiring moderate to high cooling capacity (500 W–4,000 W)

When it may not be suitable

The unit may not be suitable for enclosures that require protection ratings higher than IP54 or for installations where dimensions 597 × 417 × 380 mm cannot be accommodated. It is not intended for direct cooling of open-air equipment without an enclosed cabinet.

• Material: steel
• Protection class: IP34, IP54
• Colour: grey
• External dimensions (W × D × H): 597 mm × 417 mm × 380 mm

How to use

Install the Rittal Blue e on the roof of the enclosure following the manufacturer's mounting instructions and ensure the enclosure cut-out and fastening points match the unit's dimensions. Connect power and configure the integrated e-Comfort controller for the required temperature set points. Because the unit uses electrical condensate evaporation, no external drain connection is necessary, but verify adequate ventilation and service access for maintenance.

What to consider before purchase

• Confirm the required cooling capacity (500 W–4,000 W) for your enclosure and ambient conditions
• Check enclosure dimensions and roof-mount compatibility with the unit's external dimensions
• Verify required protection class (IP34/IP54) meets site and application requirements
• Ensure electrical supply and control integration options match your installation

Usage recommendations

For reliable operation, select a Blue e model that provides sufficient cooling margin for peak loads, set the e-Comfort controller according to the enclosure's permissible internal temperature, and allow clearance for airflow and maintenance access on the cabinet roof.
