A standard RTU uses fixed factory configurations, while a custom large-capacity RTU may be engineered around project-specific airflow, ESP, voltage, refrigerant, fresh air, curb, controls and environmental requirements.

Yes, some large commercial rooftop HVAC replacement projects may qualify for utility, state or regional energy-efficiency incentives depending on location, equipment efficiency and program requirements.

Florida RTU replacement projects should consider high temperature, humidity, coastal corrosion, fresh-air load, roof curb compatibility, wind conditions, electrical supply and local installation requirements.

Certification and compliance requirements for a U.S. rooftop HVAC project depend on the equipment, capacity, refrigerant, state and project specification. AHRI, ETL or UL and local code requirements may apply.

Yes, large rooftop HVAC platforms may use lower-GWP refrigerants such as R32 or R454B where the equipment design, certification and project requirements support the selected refrigerant.

YUJU can support project-based 20 Ton, 30 Ton, 40 Ton, 50 Ton and 60+ Ton commercial rooftop HVAC applications, subject to equipment platform and project requirements.

Required external static pressure depends on the building duct system, filters, dampers, fresh-air components, grilles and other external resistance connected to the rooftop unit.

A 40 Ton rooftop HVAC unit does not have one fixed airflow value. Required CFM depends on cooling load, supply-air temperature, humidity control, ventilation and external static pressure.
