Daikin Concentric Duct Kit for 20-Ton Rooftop Units

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.

Key Features

• 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.
