The Rittal SK3375.504 is a high-performance wall-mounted air/water heat exchanger designed to provide effective cooling for industrial electrical enclosures, automation cabinets and machinery control systems. With a cooling output of approximately 4.5 kW, it is well suited to cabinets containing variable speed drives, power electronics and other equipment that generates substantial heat during operation.
Rather than exchanging enclosure air directly with the surrounding environment, the SK3375.504 uses a closed internal air circuit and transfers unwanted heat to a connected cooling-water supply. This cooling principle helps maintain enclosure protection while reducing exposure of sensitive components to dust, oil mist and other airborne contaminants commonly found in industrial environments.
Operating from a 230 V AC single-phase 50/60 Hz supply, the SK3375.504 combines IP55 protection with a wall-mounted format and compact 220 mm depth. It provides an efficient thermal management solution for factories and machinery installations where centralised chilled water or recooling infrastructure is available.
Variable speed drives, PLC systems, power converters and other electronic equipment can create substantial thermal loads inside sealed electrical cabinets. The Rittal SK3375.504 circulates the enclosure air through its heat exchanger and transfers unwanted thermal energy to the connected cooling-water circuit, helping maintain stable operating temperatures for sensitive equipment.
The closed-loop cooling principle is particularly beneficial in manufacturing environments where conventional fan ventilation could introduce dust, oil mist or other contaminants into the enclosure. When integrated with an appropriate cooling-water system, the SK3375.504 provides efficient heat removal without requiring an individual compressor-based refrigeration circuit at the cabinet.

The SK3375.504 is designed to cool industrial electrical enclosures by transferring heat from the closed internal enclosure air circuit to a connected cooling-water system.
The SK3375.504 provides approximately 4.5 kW of cooling capacity, making it suitable for electrical enclosures with substantial thermal loads.
The Rittal SK3375.504 operates from a 230 V AC single-phase supply at 50/60 Hz.
The SK3375.504 has an IP55 protection rating, supporting its use with sealed industrial electrical and automation enclosures.
An air/water heat exchanger removes enclosure heat while maintaining a closed internal air circuit. This enables effective cooling without continuously drawing potentially dusty or contaminated ambient air over sensitive electrical components.
Rittal air/water heat exchangers provide dependable enclosure climate control for industrial automation, machine building and electrical engineering applications, combining efficient water-based heat removal with closed-loop internal air circulation to protect temperature-sensitive equipment.
