Rittal Blue e+ enclosure cooling unit, IP55, steel, 2 kW, for 450x1600x294 mm cabinets

The Rittal Blue e+ is a cabinet cooling unit designed for efficient thermal management in electrical enclosures. Certified to IP55 and constructed from steel with a grey finish, it has a compact footprint with a width of 450 mm, depth of 294 mm and height of 1600 mm. The unit combines hybrid technology and heat pipe components to reduce energy consumption while providing temperature control for sensitive electronics.

Advantages

The Blue e+ delivers significant energy savings through speed-regulated components and integrated heat pipe technology, achieving on average up to 75% lower energy use compared with conventional units. It supports multi-voltage operation for global deployment and features an intuitive touch display for straightforward operation. The mounting cut-out is standardised across four output categories, allowing the same opening for external mounting, partial internal mounting and full internal mounting.

Suitable for

• Cooling electrical and electronic enclosures in industrial environments
• Applications requiring energy-efficient continuous operation
• Sites with variable supply voltages or international installations

When it may not be suitable

This unit is intended for enclosure cooling where IP55 protection and steel construction meet site requirements; it may not be appropriate where higher ingress protection (e.g., IP66) or non-metallic enclosure materials are mandatory. Extremely compact or non-standard enclosures that cannot accommodate the specified mounting cut-out or overall dimensions will require an alternative solution.

Key specifications

• Protection class: IP55
• Material: Steel
• Colour: Grey
• Width: 450 mm
• Depth: 294 mm
• Height: 1600 mm
• Hybrid cooling with heat pipe technology for reduced energy consumption
• Speed-regulated components for variable operation and efficiency
• Multi-voltage capability for worldwide use
• Touch display for intuitive control

How to use

Install the cooling unit in the enclosure following the standardised mounting cut-out dimensions so it can be mounted externally, partially internally or fully internally according to the application. Connect the electrical supply matching the site voltage and configure the unit via the touch display, setting temperature targets or control parameters as required. Regularly check the unit for dust accumulation and inspect filters and air paths as part of routine maintenance to ensure optimal performance.

What to consider before purchase

• Verify enclosure dimensions and mounting cut-out compatibility with the unit's width, depth and height
• Confirm IP55 meets the environmental protection requirements of the installation site
• Ensure the enclosure material and structure can support steel-mounted cooling equipment
• Check the available supply voltage range at the installation site for multi-voltage compatibility

Usage recommendations

For energy-efficient operation, set control parameters to use speed-regulated modes and enable the hybrid/heat-pipe functions. Schedule periodic inspections of filters and airflow paths and ensure the touch display settings are secured to prevent unintended changes.
