Why Choose the Rittal SK3305.544 Blue e Wall-Mounted Cooling Unit?
The Rittal SK3305.544 is a high-performance Blue e wall-mounted enclosure cooling unit designed to provide reliable thermal management for industrial electrical and automation enclosures. With a rated cooling output of 1.6 kW and a 400/460 V AC three-phase, 50/60 Hz supply, it is well suited to control cabinets containing drives, power electronics, PLCs and other heat-generating equipment.
Designed for demanding industrial environments, the SK3305.544 features a robust stainless steel housing and NEMA 4X protection. The external air circuit is rated to IP34, while separate internal and external air circuits allow enclosure heat to be transferred to the surrounding environment without continuously exchanging contaminated ambient air with the protected enclosure interior.
The wall-mounted design provides a practical cooling solution where enclosure-mounted refrigeration is required, while its 358 mm depth provides a robust package for higher thermal loads. Rittal Blue e technology is engineered to combine dependable refrigeration-based cooling with efficient operation and intelligent temperature management for modern industrial applications.

Reliable Cooling for High Heat-Load Enclosures
Industrial control cabinets containing variable frequency drives, servo systems, power supplies and other electronic equipment can produce substantial heat during continuous operation. Excessive enclosure temperatures may shorten component service life, cause protective shutdowns and reduce the reliability of automated machinery.
The Rittal SK3305.544 uses refrigeration-based closed-loop cooling to transfer this heat away from the enclosure while keeping the internal and external airflow paths separated. Its 1.6 kW cooling capacity, stainless steel construction and NEMA 4X design make it particularly suitable for demanding applications where both effective thermal management and robust environmental protection are required.
Typical Applications
- Industrial electrical control enclosures.
- Variable frequency drive and motor control cabinets.
- PLC and industrial automation systems.
- Power electronics and servo control enclosures.
- Machine tool and production equipment.
- Industrial environments requiring stainless steel cooling equipment.
- Process automation and manufacturing systems.
- OEM machinery with higher enclosure heat loads.
