SK3185.730 Rittal BLUE E+ ROOF-MOUNTED COOLING UN1300 W, 700 X 308 X 560 MM (WHD)

Why Choose the Rittal SK 3185.730 Blue e+ Roof-Mounted Cooling Unit?

The Rittal SK 3185.730 is a high-efficiency Blue e+ roof-mounted enclosure cooling unit designed for reliable thermal management of industrial electrical enclosures, control panels and automation systems. Its innovative hybrid technology combines speed-regulated compressor cooling with heat-pipe operation, helping significantly reduce energy consumption while maintaining stable temperatures around sensitive electrical and electronic equipment.

With a total cooling output of 1.30 kW at L35 L35, the SK 3185.730 provides effective cooling for drives, PLCs, power electronics and other heat-generating components. Its integrated e+ controller with touch display provides intuitive operation and precise temperature management, while intelligent interfaces support modern industrial monitoring and connectivity requirements.

The cooling unit offers exceptional installation flexibility through its multi-voltage design, supporting both 110–240 V AC single-phase and 380–480 V AC three-phase supplies at 50/60 Hz. Measuring 700 × 308 × 560 mm, the roof-mounted format saves valuable enclosure wall space while providing IP54 protection for both internal and external air circuits when fitted with the supplied pleated filter.

Energy-Efficient Roof-Mounted Enclosure Cooling

Rittal Blue e+ cooling technology combines passive heat-pipe operation with variable-speed compressor refrigeration to adapt cooling performance to actual thermal demand. When ambient conditions permit, the heat-pipe circuit transfers heat without relying solely on active compressor operation, helping reduce energy consumption and mechanical wear.

When additional cooling capacity is required, the active refrigerant circuit supplements the heat-pipe system to provide up to 1.30 kW of cooling output. The roof-mounted configuration is especially useful where enclosure side panels must remain accessible or where floor and wall space are limited, while the separate internal and external air circuits help protect installed equipment from ambient contamination.

Typical Applications

• Industrial electrical control enclosures.
• Automation and PLC control panels.
• Machine-building electrical cabinets.
• Variable-speed drive and servo-control enclosures.
• Power electronics and industrial control systems.
• Manufacturing and production machinery.
• Switchgear and distribution enclosures.
• Applications requiring energy-efficient roof-mounted enclosure cooling.
