## Long description

Rittal SK 3126100 is a built-in air-to-air heat exchanger with an integrated display designed for enclosure cooling. The unit delivers a rated cooling capacity of 17.5 kW at 230 V and 50/60 Hz with a nominal input current of 0.26 A. Constructed from stainless steel and finished in grey, this wall-mounted heat exchanger includes a controller and digital temperature display to simplify setup and operation. The air/air design keeps internal and external air circuits separate, making it suitable for aggressive ambient conditions while providing reliable thermal management for control cabinets and electrical enclosures.
Advantages
The stainless steel construction and separated air circuits reduce the risk of contamination inside enclosures and improve corrosion resistance in challenging environments. Integrated controller and digital display enable visible temperature monitoring and simplified adjustments without additional control hardware. With a high cooling capacity of 17.5 kW and mains operation at 230 V, the unit supports demanding thermal loads in industrial applications while minimizing installation complexity through a fully wired, wall-mounted design.
Suitable for
Cooling of control cabinets and electrical enclosures in industrial facilities
Applications exposed to dusty, humid, or chemically aggressive ambient air
Wall-mounted installations where compact, built-in thermal management is required
Situations requiring visible temperature control via a digital display and onboard controller
When it may not be suitable
This air-to-air heat exchanger is not intended for applications that require direct liquid cooling or refrigeration-based low-temperature operation. It also may be unnecessary for very small enclosures with minimal heat dissipation where lower-capacity cooling solutions would be more cost-effective. Additionally, environments that demand hermetic separation from all external air or pressurized positive internal atmospheres may require a different cooling approach.
Key specifications
Cooling capacity: 17.5 kW
Supply voltage: 230 V, 50/60 Hz
Nominal input current: 0.26 A
Material: stainless steel enclosure
Color/finish: grey
Mounting: wall-mounted, built-in design
Controller: integrated with digital temperature display
Airflow concept: air-to-air with separate internal and external circuits
How to use
Install the Rittal SK 3126100 in the enclosure wall according to the manufacturer’s mounting instructions and ensure proper orientation and clearance for airflow. Connect the unit to a 230 V mains supply and configure the integrated controller using the digital display to set desired temperature limits and control behavior. Verify that intake and exhaust paths are unobstructed and that the external ambient conditions match the unit’s operational requirements. Perform routine visual inspections and clean external filters or grilles if applicable to maintain performance.
What to consider before purchase
Confirm that 17.5 kW cooling capacity matches the enclosure’s heat load calculations
Ensure mains supply is 230 V and can support the unit’s nominal current
Verify available wall space and clearance for a wall-mounted built-in installation
Assess ambient conditions and corrosion exposure to confirm stainless steel is appropriate
Determine whether air-to-air separation meets the application’s contamination and safety requirements
Usage recommendations
For reliable operation, use the integrated controller to maintain stable enclosure temperatures and schedule regular checks of airflow paths. In dusty or oily environments, inspect and clean inlet/outlet grilles more frequently. When integrating into existing control systems, follow Rittal wiring and grounding guidelines to ensure electrical safety and minimize interference.
