Built-in display air-to-air heat exchanger Rittal SK 3129100, 60000 W, 230 V, 50/60 Hz, stainless steel, grey

The Rittal SK 3129100 built-in display air-to-air heat exchanger provides targeted cooling for electrical cabinets and enclosures with a rated cooling capacity of 60,000 W. Designed for 230 V, 50/60 Hz supply and a nominal current of 0.8 A, this unit features a stainless steel grey housing and an integrated digital controller with temperature display. Air/air heat exchange separates internal and external air circuits, making the unit suitable for applications where ambient conditions are harsh or contaminated while keeping enclosure interiors protected.

Advantages

The heat exchanger delivers high cooling power in a compact wall-mounted, fully wired unit that includes a controller and a digital temperature display for straightforward monitoring and adjustment. Its air/air design prevents contamination of the enclosure interior since internal and external airstreams do not mix. The stainless steel housing improves resistance to corrosion and mechanical wear in demanding industrial and telecom environments.

Suitable for

• Climate control of electrical cabinets and switchgear in industrial facilities
• Cooling of telecom and network enclosures in technical rooms and outdoor cabinets
• Applications with dusty, humid or chemically aggressive external atmospheres
• Wall-mounted installations where integrated control and display simplify maintenance

When it may not be suitable

This air-to-air exchanger requires a temperature difference between the enclosure interior and the outside air to operate effectively; it is not intended for applications that demand active refrigeration below ambient temperature. It also requires adequate space for wall-mounted installation and proper airflow paths; environments that prevent sufficient external air exchange may reduce performance.

Key specifications

• Cooling capacity: 60,000 W
• Supply voltage: 230 V
• Frequency: 50/60 Hz
• Rated current: 0.8 A
• Housing material: stainless steel
• Mounting type: wall-mounted / built-in for cabinet installation
• Controller: integrated with digital temperature display

How to use

Install the unit according to enclosure manufacturer and local electrical codes, ensuring correct wall-mounted positioning and secure attachment to the cabinet. Connect the 230 V power supply and configure the integrated controller using the digital display to set the desired enclosure temperature or control parameters. Provide unobstructed inlet and outlet airflow paths on both the external and internal sides and follow routine inspection and cleaning intervals for external air filters and heat exchange surfaces to maintain performance.

What to consider before purchase

• Verify that 60,000 W cooling capacity matches the heat load of the enclosure and connected equipment
• Confirm available wall-mount space and dimensions for proper installation and access to the controller display
• Check compatibility with local power supply (230 V, 50/60 Hz) and installation regulations
• Assess ambient conditions to ensure an air/air exchanger is appropriate versus active refrigeration solutions

Usage recommendations

For reliable operation, schedule regular maintenance including cleaning or replacement of external filters, inspection of airflow paths, and verification of controller settings. In aggressive ambient conditions, use corrosion-resistant mounting hardware and follow manufacturer guidance for sealing and cable entry to preserve enclosure integrity.
