Why Choose the Rittal SK3359.500 Blue e Roof-Mounted Cooling Unit?
The Rittal SK3359.500 is an energy-efficient TopTherm Blue e roof-mounted enclosure cooling unit designed to remove excess heat from industrial electrical enclosures, automation cabinets and control systems. Its roof-mounted configuration provides effective climate control without occupying valuable space on the enclosure walls, making it particularly useful where floor space or side-by-side enclosure access is limited.
Part of the Rittal TopTherm Blue e series, the SK3359.500 features an integrated e-Comfort controller and electric condensate evaporation as standard. The condenser incorporates a hydrophobic RiNano coating to help reduce contamination, while the fully wired design and plug-in terminal strip simplify installation and commissioning.
With a total cooling output of 0.77 kW at 50 Hz under L35/L35 conditions, a 230 V AC single-phase 50/60 Hz supply and compact dimensions of 597 × 417 × 380 mm, the SK3359.500 provides dependable thermal management for industrial cabinets containing PLCs, drives, power supplies and other heat-generating electronic equipment.

Reliable Roof-Mounted Cooling for Industrial Enclosures
Electrical and electronic components such as PLCs, variable speed drives, power supplies and switching devices generate heat during operation. The Rittal SK3359.500 actively transfers this heat away from the enclosure while maintaining separate internal and external air circuits, helping protect sensitive equipment from excessive temperatures and external contamination.
Roof mounting allows the cooling unit to use otherwise unused space above the enclosure and leaves the side panels accessible for baying, doors or other equipment. Combined with its e-Comfort controller, condensate evaporation system and high internal airflow, the SK3359.500 provides an effective climate-control solution for continuous industrial applications.
Typical Applications
- Industrial automation and control cabinets.
- PLC and process control enclosures.
- Variable speed drive and motor control cabinets.
- Power electronics and power supply enclosures.
- Manufacturing and production machinery.
- Machine-building and OEM equipment.
- Electrical distribution and control systems.
- Enclosure suites where side-mounted cooling is impractical.
