SK3328.510 Rittal Blue e cooling unit Wall-mounted 2.2 kW 115 V 1~ 50/60 Hz Sheet steel

Why Choose the Rittal SK3328.510 Blue e Wall-Mounted Cooling Unit?

The Rittal SK3328.510 is an energy-efficient Blue e wall-mounted enclosure cooling unit designed to maintain controlled operating temperatures inside industrial electrical enclosures, automation cabinets and machinery control panels. Part of the proven Rittal TopTherm Blue e series, it combines effective enclosure climate control with a robust sheet steel construction and compact wall-mounted installation.

The SK3328.510 features an e-Comfort electronic controller for accurate temperature management and monitoring. Its condenser incorporates Rittal’s hydrophobic RiNano coating, while an integral electric condensate evaporation system helps manage moisture generated during cooling and reduces the need for separate condensate drainage arrangements.

With a nominal cooling capacity of approximately 2.2 kW and a 115 V single-phase 50/60 Hz supply, this cooling unit is well suited to industrial cabinets containing PLCs, drives, power electronics and other heat-generating equipment. Its wall-mounted format and 400 × 1580 × 295 mm dimensions provide substantial cooling performance without occupying valuable internal enclosure space.

Reliable Thermal Management for Industrial Enclosures

Electrical and electronic components such as variable speed drives, PLCs, power supplies and switching devices generate heat during operation. The Rittal SK3328.510 actively removes this excess heat while maintaining separate internal and external air circuits, helping prevent excessive enclosure temperatures and supporting reliable operation of sensitive equipment.

The Blue e platform is designed to combine dependable refrigeration-based cooling with intelligent temperature control and straightforward maintenance. The integrated e-Comfort controller, condensate evaporation system and RiNano-coated condenser make the SK3328.510 particularly suitable for continuous industrial applications where dependable enclosure climate control is required.
