Rittal Blue e+S SK 3484840 Wall-Mounted Cooling Unit 920W R1234yf

Unlike conventional cooling units that cycle compressors at fixed speeds, the Rittal Blue e+S SK 3484840 employs a smart e+ controller with a variable-speed rotary compressor, continuously adapting output to actual heat load. This results in precise temperature control, reduced energy consumption, and extended component lifespan—all within a compact, IP55-rated enclosure.

Highlights

• 920 W cooling capacity (L35 L35) for effective heat dissipation
• Efficient R1234yf refrigerant with low global warming potential
• Smart e+ controller with touch display for intuitive operation
• IP55 and NEMA 12 protection for demanding environments
• Wide voltage range (110-240 V) for global use

In daily use

This cooling unit is designed for wall mounting on enclosures, providing reliable temperature control for sensitive electronic components. The e+ controller allows precise temperature setting and monitoring, while the integrated interfaces (USB, Ethernet, CAN bus) enable seamless integration into automation systems. Its compact design and high air throughput ensure efficient cooling even in tight spaces.
