Rittal Blue e+ S SK3184.840 is a compact 1,000 W wall-mounted enclosure cooling unit with 380–480 V AC two-phase operation, R-513A refrigerant and energy-efficient hybrid cooling technology.
£2,278.10
The Rittal Blue e+ S SK3184.840 is a high-efficiency wall-mounted enclosure cooling unit designed to provide reliable thermal management for industrial electrical and electronic enclosures. Part of the advanced Rittal Blue e+ S series, it combines energy-efficient climate control technology with intelligent monitoring capabilities and R-513A refrigerant for modern machinery and automation applications.
With a cooling output of up to 1,000 W, the SK3184.840 is designed to dissipate heat generated by drives, PLCs, power supplies and other electronic components while maintaining a controlled enclosure environment. Separate internal and external air circuits prevent direct exchange of enclosure and ambient air, helping protect sensitive equipment from contamination while providing effective heat removal.
Designed for industrial power systems, the SK3184.840 operates from a 380–480 V AC, two-phase, 50/60 Hz supply. Its compact 300 × 570 × 159 mm construction provides substantial cooling performance with a shallow installation depth, making it particularly suitable for modern control cabinets and machinery where installation space is limited.
Industrial enclosure cooling units such as the Rittal Blue e+ S SK3184.840 remove heat generated by electrical and electronic equipment while maintaining a controlled environment inside the enclosure. The separated internal and external air circuits allow heat to be transferred to the surrounding environment without introducing unfiltered ambient air directly into the cabinet.
Blue e+ technology combines passive heat pipe operation with an active refrigerant circuit, allowing the cooling unit to adapt its operation according to thermal demand and ambient conditions. This approach helps reduce energy consumption while maintaining dependable temperature control for sensitive automation and power electronics.

The SK3184.840 is a wall-mounted cooling unit designed to remove excess heat from industrial electrical and electronic enclosures while maintaining a controlled internal temperature for sensitive equipment.
The Rittal Blue e+ S SK3184.840 provides a cooling capacity of up to 1,000 W, making it suitable for control cabinets with significant internal heat loads.
The SK3184.840 operates from a 380–480 V AC, two-phase, 50/60 Hz supply designed for industrial electrical installations.
The cooling unit uses R-513A refrigerant, supporting efficient refrigeration while offering a lower Global Warming Potential than several refrigerants traditionally used in enclosure cooling systems.
Blue e+ S technology combines a heat pipe with an active refrigerant circuit, allowing the cooling unit to adapt to changing thermal loads and use passive heat transfer whenever operating conditions permit.
Rittal Blue e+ climate control solutions are widely used by machine builders, panel builders and automation engineers seeking energy-efficient, intelligent and dependable thermal management for modern industrial enclosures.
