Commercial Rooftop Packaged HVAC Units
Integrated Cooling, Heating & Ventilation Solutions for Commercial Buildings
15 SEER2 & 18 SEER2 configurations with flexible horizontal and downflow applications.
Commercial rooftop packaged HVAC solution designed for integrated air conditioning and ventilation applications.
Rooftop packaged units integrate major HVAC functions into a single outdoor cabinet, helping simplify equipment installation and reduce the indoor space required for mechanical equipment.
YUJU EnvironTech supplies rooftop packaged HVAC solutions for commercial and light industrial applications, with configurations selected according to cooling capacity, heating requirements, airflow, fresh air demand, electrical specifications and project conditions.
15 SEER2 & 18 SEER2 Rooftop HVAC Options
High-efficiency rooftop units are available for projects requiring improved seasonal energy performance.
Depending on the selected model and configuration, inverter technology, efficient heat exchangers and advanced fan motors can help the system respond more closely to actual building load and reduce unnecessary energy consumption.
- Cooling
- Heat pump heating
- Air circulation
- Fresh air introduction
- Dehumidification
- Air filtration
- Variable-capacity operation
Key Features
High Energy Efficiency
High-efficiency configurations are designed to reduce HVAC energy consumption while maintaining stable indoor comfort.
Depending on the product platform, inverter compressor control and efficient fan technology can adjust system output according to actual operating demand.
Quiet Operation
ECM or high-efficiency fan motor options help reduce operating noise and improve airflow control.
Because the packaged equipment is installed outdoors, major refrigeration and air-moving components are located away from occupied indoor spaces.
Horizontal or Downflow Installation
Rooftop packaged units can be configured for different duct arrangements depending on building design.
| Configuration | Typical Application |
| Downflow | Supply and return ducts connect through the roof curb directly into the building. |
| Horizontal | Side duct connections are used where the building or installation layout requires horizontal airflow. |
Designed for Outdoor Installation
The packaged cabinet is designed for outdoor rooftop applications, with weather protection, thermal insulation and sealed electrical sections according to the selected equipment platform.
Single-side service access on applicable models helps simplify inspection and routine maintenance.
System Protection
Depending on configuration, equipment protection may include high- and low-pressure protection, overload protection, phase protection and temperature protection.
These functions help protect compressors, motors and electrical components during abnormal operating conditions.
Humidity Control
Rooftop packaged systems can provide cooling and moisture removal in a single air-treatment process.
Proper equipment selection and control are particularly important in hot and humid climates where both sensible cooling and latent load must be considered.
Fresh Air & Ventilation Options
For commercial buildings requiring outdoor air ventilation, rooftop units can be configured with fresh air intake options according to project requirements.
This allows cooling, heating, ventilation and filtration functions to be integrated into the building HVAC system.
Typical Applications
| • Shopping Centers | • Hotels | • Office Buildings |
| • Restaurants | • Cinemas | • Fitness Centers |
| • Retail Stores | • Factories | • Industrial Facilities |
New Construction & Rooftop Unit Replacement
Rooftop packaged units can be used for both new commercial buildings and HVAC replacement projects.
For replacement applications, dimensions, curb arrangement, supply and return openings, electrical specifications and existing duct connections should be reviewed before equipment selection.
- Existing rooftop unit model
- Cooling capacity
- Heating requirement
- Unit dimensions
- Supply and return opening dimensions
- Downflow or horizontal configuration
- Airflow requirement
- External static pressure
- Voltage, phase and frequency
- Fresh air requirement

Project-Specific Rooftop HVAC Configuration
Commercial rooftop HVAC projects often require more than a standard catalog model.
YUJU can coordinate equipment selection and project-specific configurations according to building load, climate conditions, airflow, installation dimensions and target-market requirements.
- Cooling-only or heat pump configuration
- Horizontal or downflow airflow
- Fresh air intake options
- Different cooling capacities
- Electrical specification matching
- High-efficiency configurations
- Refrigerant options according to available platforms
- Control options
- OEM and private-label configurations
Certification & Market Requirements
For international HVAC projects, required certifications depend on the destination market, product model and equipment configuration.
AHRI-certified and ETL-listed configurations may be available on applicable product models. Certification requirements should be confirmed during equipment selection and before order confirmation.
