What is the difference between a standard RTU and a custom large-capacity rooftop HVAC unit?
What Is the Difference Between a Standard RTU and a Custom Large-Capacity Rooftop HVAC Unit?
Standard rooftop HVAC units are generally produced around predefined factory configurations.
Large-capacity commercial RTUs often require more project-specific engineering because building and replacement conditions can vary significantly.
A Custom Large-Capacity RTU May Include
- Project-specific cooling capacity
- Customized voltage and frequency
- Required refrigerant platform
- Downflow or horizontal discharge
- Specific airflow
- Higher external static pressure
- Fresh-air intake or economizer options
- Existing curb coordination
- Custom supply and return openings
- Enhanced corrosion protection
- Control-system interfaces
- Market-specific certification requirements
- OEM or private-label branding
This is especially important when replacing older 20–60+ Ton rooftop units where the existing building conditions cannot always be matched by a standard catalog product.
