## Summary description

Rittal air duct system designed for use with TopTherm roof-mounted cooling/heating units SK 3386 and SK 3387 (MPN 3286970). Provides a dedicated airflow path to connect TopTherm rooftop units to enclosures, supporting safe ventilation and heat dissipation. Suitable for industrial electrical cabinets and enclosures requiring controlled airflow with factory-matched compatibility to Rittal TopTherm SK 338 series.

## Long description

The Rittal air duct system is engineered for use with TopTherm roof-mounted cooling and heating units SK 3386 and SK 3387. It establishes a dedicated airflow path between a TopTherm rooftop unit and an electrical enclosure, enabling controlled ventilation and reliable heat dissipation. The system is intended to integrate with industrial cabinets and enclosures where precise management of intake and exhaust air improves equipment thermal performance and prolongs component life.
Advantages
This air duct system provides a factory-matched connection to Rittal TopTherm roof units, ensuring correct fit and minimal installation adjustments. By directing airflow through a defined channel, it reduces turbulence and improves the efficiency of heat removal from the enclosure. The solution helps maintain consistent internal temperatures, supports safe separation of ambient and enclosure air streams, and simplifies routing for service and maintenance.
Suitable for
Industrial electrical enclosures and control cabinets using Rittal TopTherm SK 3386 / SK 3387 rooftop units
Applications that require directed airflow to manage heat-generating components such as power supplies, drives or PLC racks
Installations where separation of enclosure air from ambient air is necessary for safety or process reasons
Environments that need a factory-matched duct interface to ensure compatible thermal management
When it may not be suitable
This air duct system is specifically designed to work with the stated TopTherm rooftop series and may not fit or perform correctly with other cooling unit families or non-Rittal enclosures. It is not a standalone cooling device; effectiveness depends on correct matching with an appropriate TopTherm unit and properly sized enclosure.
Key specifications
Purpose: provides a sealed airflow path between rooftop thermal unit and enclosure
Compatibility: designed for specific TopTherm SK 3386 / SK 3387 rooftop units
Function: directs intake or exhaust air to improve heat dissipation and reduce internal turbulence
Application area: industrial electrical cabinets and enclosures
How to use
Mount the air duct system between the TopTherm rooftop unit and the enclosure according to the enclosure and unit alignment. Ensure mating surfaces are clean and that the duct is seated to create a sealed airflow channel. After mechanical installation, verify airtight connections and then operate the TopTherm unit to confirm proper airflow direction and temperature behaviour inside the enclosure. Perform routine inspection and cleaning as part of cabinet maintenance to retain optimal thermal performance.
What to consider before purchase
Confirm mechanical and dimensional compatibility with your specific enclosure and TopTherm rooftop unit model
Ensure the TopTherm unit selected has the capacity required for the enclosure heat load
Assess whether the application requires separation of enclosure and ambient air streams
Plan for access and maintenance clearance once the duct and rooftop unit are installed
Usage recommendations
Use the air duct system together with the corresponding Rittal TopTherm rooftop unit and follow the manufacturer's installation guidelines for mechanical fastening and sealing. Regularly inspect ducting connections for dust build-up or damage, and verify enclosure internal temperatures periodically to ensure the thermal management system continues to meet operational requirements.
