Product Details

Daikin Concentric Duct Kit for 20-Ton Rooftop Units CDK240

The Daikin CDK240 is a high-performance concentric duct kit designed specifically for integration with 20-ton commercial rooftop units (RTU). This essential HVAC accessory streamlines the air distribution process by transitioning the separate supply and return air streams from the rooftop unit into a single, concentric opening. By utilizing a concentric transition, the CDK240 eliminates the need for complex dual-duct roof penetrations, significantly reducing labor costs and potential leak points during installation.

Engineered for durability and aerodynamic efficiency, the CDK240 ensures balanced airflow throughout large open-span environments such as warehouses, industrial facilities, and big-box retail centers. This kit is compatible with specific Daikin, Goodman, and Amana commercial series, providing a flush-mount solution that maintains the integrity of the building’s thermal envelope.

Key Features and Technical Specifications

  • Optimized Airflow Distribution: Features a heavy-duty concentric diffuser designed for four-way blow patterns, ensuring even temperature regulation across expansive floor areas.
  • High-Capacity Compatibility: Specifically engineered for 20-ton HVAC systems, including the Daikin DPS and Goodman high-tonnage rooftop product lines.
  • Simplified Roof Penetration: Enables a single-cut installation process, reducing the structural impact on the roof and minimizing the footprint of the HVAC ductwork.
  • Durable Construction: Manufactured with galvanized steel and high-grade insulation to prevent condensation and ensure long-term reliability in demanding commercial HVAC environments.
  • Internal Return Air Path: The integrated center-return design maximizes space efficiency by pulling exhaust air back through the core of the assembly.
  • All-In-One Transition Kit: Includes the necessary concentric transition, diffuser assembly, and hardware required for a professional-grade installation.
  • Reduced Static Pressure: Aerodynamically tested components minimize resistance, supporting the SEER and EER ratings of the primary rooftop unit by maintaining efficient blower performance.
  • Weather-Tight Sealing: Designed to work in conjunction with standard roof curbs to provide a moisture-proof seal between the RTU and the interior ceiling.
