High Static Duct FCU with Dual Seal Drain Pan System Four Speed Boost Duct FCU with 5000 9500 W AEH Option

On large floor plates the terminal unit count drives the design: every additional unit is another duct connection, another condensate run, another electrical point and another commissioning node on the programme. The Midea High Static Pressure Duct Fan Coil Unit addresses that arithmetic directly — 150Pa of external static pressure carries conditioned air through long and complex duct networks, so a single unit in the 400–1800 CFM band delivering 6.6–19.9 kW of cooling serves zones that would otherwise need two or three smaller machines. Fewer units mean fewer pressure-test points, fewer control nodes and a shorter commissioning sequence, and the Eurovent-certified capacity figures support the reduced unit count at design review.

The unit is also specified for the risk that matters most in concealed installations: water. A dual-seal drainage pan with a standard extended pan provides layered protection against condensate reaching a finished ceiling below, and 400mm body height with RC3/4" connections and a ZG5/4" drain allows the unit to be coordinated in a defined ceiling zone rather than an assumed one. Water connections reverse left or right to suit riser positions, configurable electric auxiliary heating from 5000–9500W covers supplementary or peak heating loads without oversizing the base unit, and the 1.6 MPa maximum working pressure sits inside normal closed-loop practice.

Operation is where the four-speed motor with a super-high boost tier earns its place in a specification: the boost tier supports fast pull-down at commissioning demonstrations and in venues that run to event schedules rather than continuous occupancy, while the single-screw filter release keeps routine service to minutes per unit and protects the maintenance strategy over the life of the building. BMS and Modbus integration is provided through the FCU KIT, giving the controls contractor a defined interface. Standard supply is 220–240V / 1Ph / 50Hz, with OEM/ODM custom voltage from 180–440V at 50/60Hz and branding support available through Hongtai for export projects.

• 150 Pa External Static Pressure — Carries air through long, branched and heavily bent duct runs; one unit serves zones that would otherwise need two or three.
• 400–1800 CFM in One Family — Fewer terminal units per floor means fewer duct connections, condensate runs, electrical points and commissioning nodes.
• Dual-Seal Drain Pan with Standard Extended Pan — Layered condensate protection for concealed installations above finished ceilings.
• 400mm Section Height, RC3/4" Connections — Defined coordinates for ceiling zone coordination rather than an assumed void.
• Reversible Water Connections — Left or right pipe orientation matched to the riser position without re-routing the branch.
• Configurable AEH 5000–9500 W — Supplementary and peak heating covered without oversizing the water-side unit or the riser.
• Four-Speed Motor with Super-High Boost — Fast pull-down for commissioning demonstrations and event-driven occupancy profiles.
• Single-Screw Filter Release — Tool-free service access keeps maintenance visits short and the O&M strategy realistic.
• BMS / Modbus via FCU KIT — A defined interface for the controls contractor rather than a project-specific workaround.

Begin with the duct pressure budget, not the room count. Where the worst-case branch loss plus margin exceeds the medium static class, the 150Pa unit should be scheduled from the outset; an undersized static allowance is the most common reason airflow falls short at commissioning and the most expensive to correct afterwards. Then match capacity: at 6.6–19.9 kW per unit, one machine typically replaces two or three smaller terminals in a zone, which reduces duct connections, condensate runs and control nodes in proportion. Size the electric auxiliary heating from the 5000–9500W band against the winter load rather than increasing the water-side unit, and confirm that the 2-pipe arrangement matches the riser design. Hongtai's technical team can review selections against drawings before the schedule is issued.

1. Shopping Malls and Department Stores — Extended duct runs from fewer units serve large retail plates with a reduced equipment count.
2. Airport and Rail Terminals — 150Pa static pressure overcomes complex routing in high-ceiling public concourses.
3. Exhibition and Convention Halls — High-volume delivery with boost mode suits variable-occupancy event spaces.
4. Large Open-Plan Offices — Fewer, higher-capacity units reduce plant space and simplify the building services layout.
5. Hospital Inpatient Floors — Ducted delivery with defined filtration and drainage protection suits clinical floor plates.
