The Rittal Blue e+ S SK3178.801 is a compact and highly energy-efficient 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 proven Blue e+ technology with multi-voltage capability, intelligent monitoring options and environmentally considerate R-513A refrigerant.
The SK3178.801 provides a total cooling output of 0.3 kW at L35/L35, helping maintain suitable operating temperatures for PLCs, drives, power supplies and other heat-sensitive components. Separate internal and external air circuits enable efficient heat removal without introducing ambient air directly into the enclosure, while the integrated e+ controller provides precise temperature regulation.
Operating from a flexible 110–240 V AC single-phase, 50/60 Hz supply, the SK3178.801 is suitable for machinery intended for international markets. This version is supplied without an integrated condensate evaporator and features a compact 300 × 570 × 159 mm wall-mounted design for installations where enclosure space and installation depth are important considerations.
Industrial enclosure cooling units such as the Rittal Blue e+ S SK3178.801 maintain controlled internal temperatures by transferring heat away from sensitive electrical and electronic components. The separated internal and external air circuits help protect the enclosure environment while allowing heat generated by automation equipment to be dissipated effectively.
Blue e+ technology combines an active refrigerant circuit with heat pipe operation to provide efficient cooling across changing operating conditions. Together with intelligent e+ temperature control, multi-voltage compatibility and optional IoT connectivity, the SK3178.801 provides a flexible thermal management solution for modern machinery and industrial automation systems.
