SK3375.500 Rittal Air/water heat exchanger Wall-mounted 5 kW 230 V 1~ 50/60 Hz

Why Choose the Rittal SK3375.500 Air/Water Heat Exchanger?

The Rittal SK3375.500 is a high-capacity wall-mounted air/water heat exchanger designed to provide dependable cooling for industrial electrical enclosures, automation cabinets and machinery control systems. By transferring enclosure heat to a connected cooling-water circuit, it provides an efficient climate-control solution for installations where centralised chilled water or recooling infrastructure is available.

The SK3375.500 maintains a closed internal air circuit, allowing sensitive electrical and electronic equipment to be cooled without drawing potentially contaminated ambient air directly into the enclosure. An integrated e-Comfort controller provides accurate temperature regulation and monitoring, while the water-based cooling principle supports reliable operation even in demanding industrial environments.

With a total cooling output of approximately 5 kW, a 230 V AC single-phase 50/60 Hz supply and IP55 protection, the SK3375.500 is well suited to enclosures with substantial heat loads from variable speed drives, power electronics, PLC systems and industrial control equipment. Its wall-mounted format and 220 mm depth provide high cooling performance while preserving valuable internal cabinet space.

Reliable High-Capacity Water Cooling for Industrial Enclosures

Modern automation systems, variable speed drives, power electronics and industrial control components can generate significant heat inside sealed electrical cabinets. The Rittal SK3375.500 circulates enclosure air through its internal heat exchanger, transferring this unwanted thermal energy to the connected cooling-water circuit and helping maintain stable operating temperatures.

Because the internal enclosure air remains separated from the surrounding atmosphere, the SK3375.500 is particularly useful in factories where dust, oil mist or elevated ambient temperatures make open-loop ventilation unsuitable. When connected to an appropriate central cooling-water system, it provides efficient heat removal without requiring a separate refrigerant compressor circuit at each enclosure.

Typical Applications

• Industrial automation and control cabinets.
• Variable speed drive and motor control enclosures.
• PLC and process control systems.
• Power electronics and converter cabinets.
• Machine tools and production machinery.
• Manufacturing and automated production lines.
• Machine-building and OEM equipment.
• Facilities with central chilled-water or recooling systems.
