The Rittal SK3212.230 is a compact wall-mounted air/water heat exchanger designed for reliable cooling of industrial electrical and electronic enclosures. Using cooling water to transfer heat away from the enclosure, it provides an effective climate control solution where conventional ventilation with ambient air is unsuitable or where a central cooling-water supply is already available.
With a useful cooling output of approximately 0.3 kW, the SK3212.230 is well suited to smaller control cabinets containing PLCs, power supplies, control electronics and other heat-generating components. The closed internal air circuit helps prevent contaminated ambient air from entering the enclosure while continuously transferring internally generated heat to the water circuit.
The SK3212.230 operates from a 230 V AC single-phase, 50/60 Hz supply and features a compact 150 × 300 × 85 mm (W × H × D) format. With IP55 protection and a depth of only 85 mm, it provides efficient enclosure cooling while minimising external installation space.
Air/water heat exchangers cool an enclosure by transferring thermal energy from the internal circulating air to a connected cooling-water circuit. Because the enclosure air remains separated from the surrounding atmosphere, sensitive electrical and electronic equipment can be cooled without continuously introducing dust, dirt or other airborne contaminants.
The Rittal SK3212.230 is particularly suitable for machinery and automation installations where cooling water is available from a central recooling or process-water system. Its compact dimensions, 230 V AC supply and closed-loop cooling principle make it a practical solution for maintaining dependable operating temperatures in smaller industrial enclosures.
