What Are RTU Curb Adapters?
If you’re in charge of facility management or HVAC installation, you know that replacing a rooftop unit (RTU) can be a headache—especially when the new unit doesn’t match the existing curb. That’s where RTU curb adapters come in. These custom-fabricated components bridge the gap between your old curb and new unit, ensuring a perfect fit without costly structural modifications.
Why Are Curb Adapters Necessary?
Many RTUs last 15–20 years, but when it’s time for a replacement, manufacturers may have changed their unit footprints. Instead of tearing up the roof, curb adapters retrofit the new unit to the old curb, reducing downtime, labor costs, and potential roofing issues.
Key Benefits of RTU Curb Adapters:
- Faster Installations: Minimize HVAC downtime for buildings.
- Cost Savings: Avoid expensive curb replacement and roof modifications.
- Custom Fit: Engineered to match different unit models and manufacturers.
- Improved Efficiency: Ensure proper airflow and system performance.
Types of RTU Curb Adapters
Not all curb adapters are the same. Depending on your project needs, you may require a specific type:
1. Standard Curb Adapters
- Used for basic retrofits where the new RTU is slightly different from the old one.
- Typically made from galvanized steel or aluminum for durability.
2. Transition Curb Adapters
- Designed for significant footprint differences between the old and new RTU.
- Often include duct transitions to ensure proper airflow.
3. Sound-Attenuating Curb Adapters
- Equipped with insulation or sound-dampening features.
- Ideal for installations in schools, offices, or residential areas where noise reduction is critical.
4. Specialty Curb Adapters
- Custom-built for complex installations, including multi-zone systems or specific manufacturer requirements.
How to Choose the Right Curb Adapter
Selecting the correct RTU curb adapter depends on several factors:
✅ Unit Specifications: Verify dimensions, weight, and airflow requirements. ✅ Duct Transitions: Ensure proper connections for optimal system efficiency. ✅ Roofing Material & Load Capacity: Avoid unnecessary stress on the building. ✅ Manufacturer Compatibility: Work with experienced fabricators who can match your new unit with the existing curb.
