Why Choose the Rittal Blue e+ SK3189.940 Wall-Mounted Cooling Unit?
The Rittal Blue e+ SK3189.940 is a high-performance wall-mounted enclosure cooling unit designed for efficient thermal management of industrial electrical and electronic enclosures. Part of the advanced Rittal Blue e+ climate control range, it combines intelligent cooling technology with robust sheet-steel construction and precise temperature control for demanding machinery and automation applications.
The SK3189.940 provides approximately 5.8 kW cooling output, making it suitable for larger control cabinets with substantial internal heat loads from variable speed drives, power electronics, PLC systems and other industrial equipment. Blue e+ hybrid technology combines a passive heat pipe with an active refrigerant circuit, allowing the unit to adapt its cooling operation to actual thermal demand and helping reduce energy consumption.
Designed for wall mounting, the SK3189.940 features a robust sheet-steel housing with a depth of 393 mm. The internal cooling circuit provides IP55 protection, maintaining separation between enclosure and ambient air to help protect sensitive components against dust, moisture and contaminants present in industrial environments.

High-Performance Climate Control for Industrial Enclosures
Industrial control cabinets containing high-power drives, power electronics and automation equipment can generate significant amounts of heat. The Rittal Blue e+ SK3189.940 transfers this heat away from the enclosure while maintaining separate internal and external air circuits, helping preserve the protected internal environment required by sensitive electrical components.
Blue e+ hybrid technology combines passive heat pipe cooling with an active refrigerant circuit. When ambient conditions permit, the heat pipe can contribute to heat removal with low energy consumption, while active cooling provides additional capacity as thermal demand increases. This demand-based approach helps improve overall energy efficiency compared with conventional fixed-output enclosure cooling systems.
Typical Applications
- Large industrial electrical control cabinets.
- Variable speed drive and motor control enclosures.
- PLC and process automation systems.
- Machine tools and production machinery.
- Power electronics and converter cabinets.
- Manufacturing and factory automation systems.
- Industrial equipment with high internal thermal loads.
