Why Choose the Rittal SK 3329.500 TopTherm Blue e Wall-Mounted Cooling Unit?
The Rittal SK 3329.500 is an energy-efficient TopTherm Blue e wall-mounted cooling unit designed for reliable climate control of electrical and electronic enclosures in industrial environments. As part of the proven Rittal Blue e cooling range, it combines efficient refrigeration technology, intelligent e-Comfort control and robust sheet steel construction for dependable enclosure cooling.
The unit delivers precise temperature management for heat-sensitive components while helping improve energy performance compared with conventional fixed-output enclosure cooling. Its hydrophobic RiNano-coated condenser supports easier maintenance, while the integral electric condensate evaporator helps manage moisture produced during cooling without requiring a separate condensate drain under normal operating conditions.
With a total cooling output of 2.55 kW at L35/L35 and 50 Hz, a 230 V single-phase, 50/60 Hz supply and dimensions of 400 × 1580 × 295 mm (W × H × D), the SK 3329.500 is well suited to wall-mounted installation on industrial enclosures. The external circuit is rated to IP34, while the internal circuit provides IP54 protection.
