Rittal Blue e stainless steel cooling unit model 3359600 with IP34/IP54 protection

Rittal Blue e stainless steel cooling unit model 3359600 is a roof- or panel-mounted air conditioning solution for electrical enclosures. Built from stainless steel and certified to IP34 and IP54 degrees of protection, this unit provides corrosion-resistant housing and protection against dust ingress and splashing water. The cooling unit is part of the Blue e range of energy-efficient roof-mounted units and features an integrated e-Comfort controller, a RiNano-coated condenser and electrical condensate evaporation.

Advantages

The stainless-steel construction offers enhanced corrosion resistance for installations in humid or chemically aggressive environments. IP34/IP54 ratings ensure mechanical protection for internal components against dust and splashing water, making the unit suitable for indoor and sheltered outdoor use. Energy-efficient design and the e-Comfort controller allow precise temperature management and reduced operating costs compared with non-controlled systems. RiNano coating on the condenser improves long-term heat-exchange performance and reduces maintenance frequency, while built-in condensate evaporation removes the need for external drainage.

Suitable for (tasks / use cases)

• Cooling electrical and electronic control cabinets in industrial production areas
• Temperature control for outdoor or semi-sheltered enclosures where corrosion resistance is required
• Applications that require roof- or panel-mounted installation to save internal space
• Enclosures housing heat-sensitive drives, PLCs, and communication equipment

When it may not be suitable

This unit is intended for enclosures that accept roof- or panel-mounted cooling and for environments where IP34/IP54 protection is sufficient. It may not be appropriate for fully outdoor exposed installations that require higher ingress protection or for submerged, dust-tight, or washdown environments. Also, if a cooling capacity outside the Blue e output range (500 W–4,000 W) is required, a different model should be selected.

Key specifications

• Cooling capacity category: part of the Blue e roof-mounted range (500 W to 4,000 W)
• Housing material: stainless steel
• Protection class: IP34 and IP54 (as specified for different installation variants)
• Controller: integrated e-Comfort controller for temperature regulation
• Condenser protection: RiNano coating for improved corrosion and contamination resistance
• Condensate management: electrical condensate evaporation (no external drain required)
• Mounting: roof-mounted or panel-mounted for electrical enclosures

How to use

Install the cooling unit on the roof or panel of the enclosure following the manufacturer's mounting and sealing instructions to maintain the stated protection rating. Connect electrical supply and communications according to the e-Comfort controller wiring diagrams so temperature setpoints, alarms and fan control functions are available. Set the controller to the required target temperature and monitor the enclosure temperature and condensate function during initial operation. Perform regular visual inspections of the condenser and seals and follow scheduled maintenance to ensure efficient heat exchange and corrosion protection.

What to consider before purchase

• Confirm required cooling capacity for the enclosure and ensure it falls within the Blue e range (500 W–4,000 W)
• Verify that IP34/IP54 protection is adequate for the installation location and environmental conditions
• Ensure roof- or panel-mounted installation is compatible with the cabinet design and available space
• Check electrical supply requirements and compatibility with the integrated e-Comfort controller

Usage recommendations

For reliable operation, install the unit in accordance with Rittal installation instructions, set temperature limits via the e-Comfort controller, and schedule periodic inspections of the condenser, RiNano coating condition and enclosure seals. Use the condensate evaporation feature as intended and avoid installing the unit in areas subject to direct high-pressure washdown or full immersion.
