The Rittal SK 3363.100 is a compact wall-mounted air/water heat exchanger designed for reliable cooling of industrial electrical and electronic enclosures. Using water as the cooling medium, it transfers heat from the enclosure's internal air circuit to an external cooling-water system without introducing ambient air into the enclosure.
Designed for demanding industrial environments, the SK 3363.100 provides a total cooling output of 0.5 kW at L35/W10 with a water flow of 400 l/h. Its copper/brass water-carrying components, IP55 protection rating and ability to operate at ambient temperatures of up to 70 °C make it a practical solution where conventional ambient-air cooling may be unsuitable.
The unit operates from a 230 V AC, single-phase, 50/60 Hz supply and measures just 280 × 550 × 120 mm (W × H × D). External or fully internal mounting is supported, while flexible water connection options and a factory-set Basic controller simplify installation and operation.
Air/water heat exchangers cool electrical enclosures by transferring heat from the internal enclosure air to a separate water circuit. Because the enclosure's internal air remains isolated from the surrounding environment, this cooling principle is particularly useful where ambient air contains dust, dirt or other contaminants that should not enter the enclosure.
The Rittal SK 3363.100 combines this closed-circuit cooling principle with an IP55 enclosure rating and an unusually broad ambient operating range of 1–70 °C. Flexible external or internal mounting and compact dimensions make it suitable for industrial installations where space, environmental protection and reliable heat removal are important considerations.
