Rittal wall-mounted cooling units
Blue e+ (1.6–5.5 kW)
Cooling output 1600 W–5500 W Heat pipe technology Speed-regulated components
The Rittal Blue e+ wall-mounted cooling units provide enclosure cooling in output categories from 1600 W to 5500 W. The Blue e+ concept is designed for efficiency—Rittal states that average energy savings of 75% can be achieved using speed-regulated components and heat pipe technology.
Versions are available in sheet steel and stainless steel, allowing you to align the housing material with the surrounding environment. For contaminated environments, Rittal also offers a chemical-industry variant with a special surface finish to help protect components (e.g., where air may contain sulphuric acid aerosols).

What special features are available for Rittal Blue e+ wall-mounted cooling units?
These wall-mounted cooling units focus on energy-efficient enclosure cooling with robust options for different installation environments.
Efficiency & cooling concept
- Cooling output classes from 1.6 kW to 5.5 kW
- Heat pipe technology as part of the efficiency concept
- Speed-regulated components for demand-based operation
- Rittal states average energy savings up to 75% (application-dependent)
Materials & environment variants
- Available in sheet steel and stainless steel versions
- Chemical-industry variant with special surface finish for contaminated environments
- Designed for enclosure / cabinet wall mounting
- Useful where stable enclosure temperature supports uptime and component life
Selection hint: Choose stainless steel where corrosion resistance is a priority. In contaminated atmospheres, consider the chemical version for added component protection.

Where are wall-mounted cooling units used?
Wall-mounted cooling units are used to stabilize enclosure temperatures and protect sensitive electrical and automation components in industrial environments.
Typical applications
- Industrial control cabinets and enclosures with significant heat load
- Production lines and automation cells needing stable cabinet climate
- Installations where efficiency is a key requirement (Blue e+ concept)
- Contaminated environments (use the chemical variant where applicable)
Why teams choose Blue e+
- Energy efficiency concept with heat pipe + speed-regulated components
- Output range covering 1.6–5.5 kW classes
- Material choice between sheet steel and stainless steel
- Environment variants including chemical version for contaminated air
Short definition: A wall-mounted cooling unit removes heat from an electrical enclosure to help maintain safe internal temperatures and support reliable operation.
FAQ: Rittal wall-mounted cooling units (Blue e+)
Quick answers to help you choose the right output class, material, and environment variant.
The Blue e+ wall-mounted cooling units in this family cover output categories from 1600 W to 5500 W (i.e., 1.6–5.5 kW).
Rittal describes the Blue e+ approach as using heat pipe technology together with speed-regulated components. Rittal states that average energy savings of 75% can be achieved, depending on the application and operating profile.
Use the chemical variant in contaminated environments where a special surface finish helps protect components—especially in applications where air may contain sulphuric acid aerosols.
Rittal indicates availability in sheet steel and stainless steel versions for this Blue e+ wall-mounted family.
