460V 3-Phase Commercial HVAC OEM Solution
R32 5-Ton Air Handler + Top-Discharge Outdoor Unit for U.S. Commercial & Controlled-Environment Projects
Customized 460V / 3Ph / 60Hz HVAC configuration with ECM airflow, high static pressure capability and project-specific OEM support.
Commercial and industrial facilities often require electrical, airflow and operating specifications that differ significantly from standard residential HVAC systems.
This customized YUJU HVAC solution combines a 460V three-phase top-discharge outdoor unit with a matched air handler, ECM blower, R32 refrigerant platform and adjustable external static pressure.
The configuration is suitable for controlled-environment facilities, grow rooms, warehouses and selected commercial applications requiring high airflow and reliable continuous operation.

Why 460V / 3-Phase HVAC?
Many industrial and commercial facilities in North America use three-phase electrical systems for larger HVAC and mechanical equipment.
A 460V three-phase configuration can be appropriate where the building electrical infrastructure is already designed around commercial power distribution.
- Industrial facilities
- Controlled-environment agriculture
- Grow rooms
- Warehouses
- Production spaces
- Commercial buildings
- Equipment rooms
- Specialized HVAC retrofit projects
ECM Air Handler for Adjustable Airflow
The indoor air handler uses a multi-speed ECM blower platform with several available airflow settings.
This provides greater flexibility when matching the equipment to different duct systems and external static pressure conditions.
1,044 / 1,256 / 1,442 / 1,672 / 1,831 CFM
Actual airflow selection should be based on cooling load, duct resistance, required air distribution and project operating conditions.
High Static Pressure Capability
Commercial duct systems often have greater airflow resistance than simple residential installations.
This air handler provides an external static pressure range up to approximately 0.8 in.W.C. / 200 Pa, allowing it to support more demanding duct configurations.
The correct fan setting should be confirmed using the required project airflow and calculated external static pressure. Maximum ESP alone should not be used as the basis for air-handler selection.
R32 Refrigerant Platform
The system is configured around an R32 refrigeration platform with electronic expansion valves on both indoor and outdoor sides.
The outdoor unit uses a twin-rotary compressor and DC fan motor to support variable-capacity operation.
- R32 refrigerant
- Twin-rotary compressor
- Electronic expansion valve
- DC outdoor fan motor
- ECM indoor blower
- Variable cooling-capacity range
Top-Discharge Outdoor Unit
The outdoor unit uses a compact top-discharge configuration.
Vertical condenser airflow can be useful in projects where hot discharge air needs to be directed upward and away from neighboring equipment.
Actual installation clearance should be confirmed according to the selected model and project layout.
Refrigerant Piping Capability
| Piping Parameter | Value |
| Liquid Line | 3/8 in. / Φ9.52 mm |
| Gas Line | 7/8 in. / Φ22.23 mm |
| Maximum Pipe Length | 150 ft |
| Maximum Height Difference | 50 ft |
Customized HVAC for Controlled Environments
Controlled-environment facilities can have significantly different operating requirements from conventional comfort air-conditioning projects.
High internal heat loads, long operating hours, humidity requirements and process-specific airflow can all influence HVAC equipment selection.
- Cooling load
- Sensible / latent load ratio
- Required airflow
- External static pressure
- Operating hours
- Indoor temperature
- Humidity requirement
- Outdoor design temperature
- Electrical infrastructure
- Redundancy requirements

Frequently Asked Questions
Can YUJU customize 460V three-phase HVAC systems?
YUJU can coordinate selected commercial HVAC platforms according to voltage, phase, capacity and application requirements.
Can the indoor and outdoor units use different voltages?
Yes, depending on the selected system architecture. This project uses a 460V three-phase outdoor unit and a 277V single-phase indoor air handler.
Is this system suitable for grow rooms?
It can be considered for controlled-environment applications, but equipment selection should be based on actual sensible and latent loads, airflow, humidity and operating conditions.
Can airflow and static pressure be customized?
Airflow and external static pressure requirements can be reviewed during project selection and matched to suitable air-handler and fan configurations.
Can this platform be private labeled?
OEM and private-label options can be evaluated according to the selected manufacturing platform, order quantity and project requirements.
