If you’re new to the HVAC industry or managing facility upgrades, you might wonder: What is a curb adapter? At Madon Sheet Metal, we provide not only the answer but the solutions you need to streamline your next project.
The Role of Curb Adapters in HVAC Installations
When a building is constructed, the roof is prepped for HVAC installation by cutting an opening and installing a roof curb. The roof curb supports the weight of the HVAC rooftop unit (RTU) and provides a connection point for supply and return air ducts. This ensures efficient airflow into the building’s HVAC system.
Over time, HVAC units require upgrading or replacement. Often, the new RTU’s size and ductwork layout differ from the existing unit. Removing the old curb to install a new one involves costly downtime, re-roofing, and the risk of leaks. This is where curb adapters come into play. Curb adapters allow the new unit to fit seamlessly onto the existing curb, redirecting supply and return openings to align perfectly with the ductwork.
How Curb Adapters Work
Every HVAC manufacturer has unique roof curb layouts, making it challenging to replace units without altering the existing infrastructure. Additionally, advancements in HVAC technology often mean smaller, more efficient units, further complicating retrofits.
For example, here’s how two major manufacturers’ layouts might differ:
- Carrier RTU Layouts: Supply and return openings are positioned in one configuration.
- Trane RTU Layouts: Openings differ in size and placement, requiring adjustments for proper alignment.
A well-designed curb adapter ensures minimal air resistance (static pressure) by strategically aligning the new unit’s supply and return openings with the existing curb. This reduces energy costs and maintains the system’s efficiency.
