Rittal wall-mounted cooling units
Blue e+ (1.6–5.5 kW)
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?

Model overview (how do I compare options)?
Use the overview below to align output class, material, and environment variant with your enclosure cooling requirements.
| Variant | Mounting | Cooling output | Efficiency concept | Material |
|---|---|---|---|---|
| Blue e+ wall-mounted cooling unit
General-purpose enclosure cooling
|
Wall-mounted | 1600–5500 W | Heat pipe technology + speed-regulated components | Sheet steel / stainless steel |
| Blue e+ wall-mounted cooling unit (chemical)
For contaminated environments
|
Wall-mounted | 1600–5500 W | Heat pipe technology + speed-regulated components | Special surface finish (variant family) |
Selection guidance: confirm cooling demand (thermal load), then select material and environment variant. Energy savings depend on operating profile and installation conditions.
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
