## Summary description

Rittal Blue e+ is an industrial cooling unit for electrical enclosures with 4.2 kW cooling capacity, steel construction and IP55 protection. Designed for cabinet installation, it provides controlled temperature management for control panels, switchgear and electronics in harsh environments. Suitable for manufacturing, automation and infrastructure applications.

## Long description

The Rittal Blue e+ is a cabinet cooling system that combines hybrid heat pipe technology with speed‑regulated components to reduce energy consumption. Designed for industrial enclosures, it offers multi‑voltage capability for use in different regions and an intuitive touch display for straightforward operation. Constructed from steel with a grey finish, the unit has external dimensions of 450 mm width, 393 mm depth and 1600 mm height and meets IP55 protection class requirements.
Advantages
Hybrid technology with heat pipes and frequency‑controlled components yields average energy savings of around 75% compared with conventional cooling systems. The unit’s multi‑voltage capability allows worldwide deployment without complex electrical adaptations. Identical mounting cut‑outs for the four output categories simplify replacement and installation. The touch display enables intuitive control and monitoring of operating parameters.
Suitable for
 Air conditioning and cooling of electrical and electronic enclosures
 Industrial control cabinets in manufacturing and processing plants
 Applications requiring IP55-rated protection against dust and water jets
 Installations where energy efficiency and reduced operating costs are priorities
When it may not be suitable
This unit is intended for cabinet cooling and may not be appropriate for open‑frame equipment or spaces that require direct room climate control. Very small enclosures with different dimensional constraints or applications needing higher IP ratings than IP55 should be evaluated for alternative solutions.
Key specifications
 Cooling concept: Hybrid (heat pipe + speed‑regulated components)
 Average energy savings: approx. 75% (compared to conventional systems)
 Protection rating: IP55
 Material: Steel
 Finish / colour: Grey
 Dimensions (W×D×H): 450 × 393 × 1600 mm
 Control: Touch display

How to use
Mount the unit to the cabinet using the specified cut‑out which is identical across the four output categories; the product supports external mounting, partial internal mounting and full internal mounting. Connect the electrical supply according to local regulations and select the appropriate voltage setting if required. Use the touch display to set temperature targets and fan speed modes; the controller adjusts components automatically to maintain the setpoint while minimising energy consumption.
What to consider before purchase
 Verify cabinet internal dimensions and the specified mounting cut‑out match the enclosure
 Confirm IP55 is sufficient for the site environmental conditions
 Ensure the unit’s cooling capacity matches the heat load of installed components
 Check local electrical standards and the required voltage range for multi‑voltage operation
Usage recommendations
For optimal efficiency, set temperature differentials conservatively and allow the controller to regulate fan speeds; perform regular filter and heat‑exchanger maintenance according to the manufacturer’s schedule to preserve energy savings and IP55 protection.
