Blue e Wall-Mounted Cooling Units Top Therm 0.3 - 4 kW

Rittal Blue e TopTherm wall-mounted cooling units provide enclosure cooling capacities from 0.3 to 4 kW for industrial control and automation applications. The series includes multiple cooling-output, voltage and material configurations, allowing the cooling unit to be selected according to enclosure heat load, ambient conditions and available power supply.

Depending on the article number, Blue e wall-mounted cooling units are available in sheet steel or stainless steel and with different electrical configurations. Use the model table and selection guide below to identify the appropriate configuration for your application.

How to Select a Blue e Wall-Mounted Cooling Unit

Selecting an enclosure cooling unit should not be based on enclosure dimensions alone. Two enclosures of the same size can require very different cooling capacities depending on the heat generated by drives, power supplies, PLCs, transformers and other installed components.

Before selecting a Blue e model, check the following operating conditions.

1. Determine the Required Cooling Output

Start with the heat generated by the electrical components inside the enclosure and consider the ambient temperature and required internal enclosure temperature.

The required cooling capacity should provide sufficient margin under the actual operating conditions without relying only on the physical size of the enclosure.

The model table below lists cooling output at defined L35 and L50 operating conditions so that models can be compared under consistent conditions.

2. Match the Power Supply

Blue e wall-mounted cooling units are available in different electrical configurations depending on the model.

Check the available supply voltage, number of phases and frequency at the installation site before selecting an article number. The range includes configurations for 115 V, 230 V, 400 V and selected 460 V applications.

Always match the exact model to the site's electrical supply rather than selecting by cooling output alone.

3. Select the Appropriate Material

Sheet steel versions are generally suited to standard industrial indoor environments where painted enclosure surfaces provide suitable protection.

Stainless steel versions are available for applications requiring greater corrosion resistance or where the cooling unit needs to match a stainless-steel enclosure.

Material selection should be based on the actual installation environment rather than appearance alone.

4. Check the Mounting Arrangement

Blue e wall-mounted cooling units can support different mounting arrangements depending on the model and installation requirements.

External mounting minimizes the amount of cooling-unit body extending into the enclosure. Partial internal or internal mounting can be considered where external projection needs to be reduced and sufficient enclosure space is available.

Because the required enclosure cut-out depends on the mounting arrangement and individual cooling-unit model, confirm the installation dimensions before machining the enclosure.

5. Confirm the Exact Article Number

Cooling output alone is not enough to identify the correct Blue e unit.

Before ordering, confirm:

• Required cooling output
• Ambient and target enclosure temperature
• Supply voltage, phase and frequency
• Sheet steel or stainless steel
• Available enclosure dimensions
• Mounting arrangement
• Required protection or environmental conditions
• Existing cooling-unit article number when selecting a replacement

Use the model table above to compare available article numbers after these requirements have been established.

Products Application

Blue e wall-mounted cooling units are used where heat generated inside an electrical enclosure cannot be dissipated adequately by natural convection or simple ventilation while a closed enclosure environment needs to be maintained.

Typical applications include:

• Industrial control and automation enclosures
• Machine control cabinets
• Drive and inverter enclosures
• Electrical distribution and control systems
• Production and process equipment
• Panel-building projects requiring dedicated enclosure climate control

The final cooling solution should be selected according to the actual thermal load and installation environment rather than application type alone.

3 Q:How do I choose the correct Blue e cooling capacity for my enclosure?

A: Start with the heat generated by the electrical components inside the enclosure, then consider the ambient temperature and required internal temperature. Compare the required cooling output with the Blue e model ratings under the specified operating conditions. Enclosure size alone is not sufficient, as cabinets of similar dimensions can have very different heat load

4 Q:What information should I provide when requesting a quotation?

A: Provide the Rittal article number if known, quantity and destination. For model selection, also provide cooling requirements, voltage, enclosure dimensions and ambient conditions.

5 Q:Can I replace an existing Rittal cooling unit with another Blue e model?

Yes, if the replacement meets the required cooling performance and installation conditions. Check voltage, dimensions and mounting cut-out before replacement.
