The Daikin NEXIO MAX DVH0903W000001S is the high-static configuration of the 7.5 ton (90,000 BTU) DV Series inverter packaged heat pump, rated for up to 2.0 in. W.C. maximum external static pressure β versus 1.4 in. W.C. on the standard DVH0903D. It delivers the same 22.0 IEER / 12.4 EER efficiency from the same variable-speed scroll inverter compressor on R-32 refrigerant, purpose-built for applications where ductwork resistance exceeds what the standard-static platform can overcome.
High-static applications are more common than many specifiers initially expect. Long duct runs, undersized existing ductwork on retrofit projects, high-efficiency filtration media with significant pressure drop, VAV systems with high-pressure zone dampers, and buildings with complex supply air distribution layouts all push static pressure requirements beyond the 1.4 in. W.C. ceiling of standard commercial rooftop units. The DVH0903W addresses this directly β same cabinet footprint, same curb compatibility, same inverter performance platform, with the additional static pressure headroom that demanding duct systems require.
The indoor section delivers 2,950 CFM nominal airflow through a direct-drive 3.5 HP blower supporting up to 2.0 in. W.C. external static pressure. The inverter compressor continuously modulates speed to match real-time building load, eliminating fixed-speed on/off cycling and maintaining tight temperature control across all occupancy levels. A subcooling heat exchanger, vapor-injection solenoid, and electronic expansion valves on both indoor and outdoor coils optimize the refrigerant circuit across all operating modes: cooling, heating, defrost, oil return, and hot gas reheat on HGRH-configured models. A dedicated BACnet PCB is physically installed in the indoor control panel as standard for native BAS integration with no field-add cards required.

FAQs
Q: What is the difference between the DVH0903W000001S and the DVH0903D000001S?
A: External static pressure rating only. The DVH0903W (W = high static) is rated for up to 2.0 in. W.C. maximum external static pressure; the DVH0903D (D = standard static) is rated for 1.4 in. W.C. All performance, electrical, refrigerant, and physical specs are otherwise identical β same 90,000 BTU capacity, 22.0 IEER, 2,950 CFM, 3.5 HP blower, 49.9A MCA, 335 oz. R-32 charge, and 1,293 lb. operating weight.
Q: When should I specify the high-static W model instead of the standard D model?
A: Specify the DVH0903W when your duct system's total external static pressure exceeds 1.4 in. W.C. Common triggers include long supply and return duct runs, undersized existing ductwork on retrofit projects, high-MERV filtration with significant pressure drop, VAV systems with zone dampers, or complex multi-branch supply air distribution. When in doubt, run a duct static pressure calculation before specifying β oversizing static pressure capacity costs nothing in performance but undersizing it will reduce airflow and comfort.
Q: Does the high-static model have a different blower motor than the standard model?
A: At 7.5 tons, no β both the DVH0903D and DVH0903W use the same 3.5 HP direct-drive blower motor at 11.7A FLA. The higher static capability at the W configuration comes from the blower wheel and motor operating characteristics rather than a motor swap. Note that on the 10 and 12-ton W models, the blower motor does step up to 5.0 HP with a higher FLA to handle the increased static and airflow demands.
Q: What is the IEER efficiency rating?
A: 22.0 IEER / 12.4 EER β identical to the standard-static DVH0903D. The high-static configuration does not affect the unit's efficiency ratings.
Q: What are the electrical requirements?
A: 208/230V, 3-Phase, 60 Hz. Minimum Circuit Ampacity (MCA) is 49.9A and maximum overcurrent protection is 60A β same as the standard-static DVH0903D. Power supply conduit knockout is 1.375 in. diameter; low-voltage conduit is 0.5 in. diameter.
Q: Is BACnet MS/TP standard on the high-static model?
A: Yes. All DV Series NEXIO MAX units include a dedicated BACnet PCB physically installed in the indoor control panel as standard. Native BAS integration requires no field-add communication cards regardless of static pressure configuration.
Q: Is there a 460V high-static version of the 7.5-ton available?
A: Yes β the DVH0904W000001S is the 460V, 3-Phase high-static variant. Contact us at 678-535-7176 to confirm availability.
Q: What does this unit weigh and how does it ship?
A: Operating weight is 1,293 lbs. and ship weight is 1,365 lbs. β identical to the standard-static DVH0903D, as both share the same cabinet platform. Units ship LTL freight to all 48 contiguous states. Call 678-535-7176 for a freight quote before ordering.
