Rittal SK3364.500 wall-mounted air/water heat exchanger providing 1 kW cooling output with an e-Comfort controller, 230 V single-phase 50/60 Hz supply and IP55 protection for industrial enclosure cooling.
£875.03
The Rittal SK3364.500 is a compact wall-mounted air/water heat exchanger designed to provide reliable cooling for industrial electrical enclosures and control cabinets in demanding environments. Using cooling water to transfer heat away from the enclosure, it offers an efficient thermal management solution where a centralised cooling-water supply is available.
Designed for ambient temperatures of up to 70 °C, the SK3364.500 combines a closed internal air circuit with flexible water connection options and an integrated e-Comfort controller. The controller is factory-set to 35 °C and provides precise enclosure temperature regulation, while the copper/brass water-carrying components provide dependable heat transfer.
With a total cooling output of 1 kW at L35/W10 with 400 l/h water flow, a 230 V AC single-phase 50/60 Hz supply and compact dimensions of 280 × 550 × 120 mm, the SK3364.500 provides effective enclosure cooling while requiring minimal installation space.
The Rittal SK3364.500 circulates enclosure air through its internal heat exchanger, transferring unwanted thermal energy to the connected water circuit. Because the enclosure air remains separated from the surrounding environment, sensitive electrical components can be cooled without introducing dust, oil mist or other airborne contaminants directly into the cabinet.
This cooling principle is particularly effective in manufacturing facilities with central cooling-water or recooling systems. The combination of a 1 kW cooling output, high-temperature capability and e-Comfort temperature control makes the SK3364.500 suitable for continuous operation in demanding automation and machine-building applications.
