Midea Ducted FCU with Reversible Left/Right Pipe Connections 3Row 4Row DC Duct FCU Modbus and V8 Integration

Concealed ducted terminals are the part of a design most exposed to coordination change, because duct routes, riser positions and ceiling zones move after the drawings are issued. The Midea Medium Static Pressure Duct Fan Coil Unit is specified to absorb that movement: external static pressure is selectable at 12, 30 or 50Pa on DC models through the PCB or wired controller, water connections reverse from left to right on site on AC models, and return air can be drawn from the rear or the bottom. Across the combined AC and DC range the family covers 400-1200 CFM and 2.35-13.78 kW of cooling, so one schedule entry serves guestrooms, cellular offices, retail units and clinical spaces at different duct lengths.

The section and coil options are what make the unit work across new-build and retrofit: 241mm body height on AC models and 261mm on DC models sits above a standard ceiling grid, and three-row and four-row coil options match two-pipe or four-pipe hydraulics while allowing capacity and water-side pressure drop to be tuned to the plant. RC3/4" connections and a 1.6 MPa maximum working pressure sit inside normal practice, the enlarged drain pan option is available where the ceiling void is tight or the finished surface below is sensitive, and the filter assembly extracts in multiple directions so service access works whatever the void geometry turns out to be.

For specifications carrying an energy or controls clause, the DC inverter brushless range offers seven fan speeds for commissioning balance, up to 30% lower fan energy and native V8 controller integration where fan coils sit alongside Midea VRF outdoor systems. XYE and PQE ports provide central control and Modbus RTU connectivity for a clean handover to the controls contractor, and the range runs on 220-240V / 1Ph / 50Hz with an electric auxiliary heating option. Hongtai supports export and project specifications with OEM/ODM custom voltage from 180-440V at 50/60Hz, project branding and protocol options.

• Selectable ESP 12/30/50 Pa — Static pressure is set at commissioning to match the installed ductwork, so the design is not committed to an assumed pressure drop.
• Site-Reversible Water Connections (AC) — Left or right piping orientation is changed on site; riser surprises do not become equipment variations.
• Rear or Bottom Return Air — Both configurations available within one unit, so the return path follows the ceiling zone rather than a bespoke plenum.
• 241mm / 261mm Section Height — Fits above standard ceiling grids without dropping the ceiling line in the occupied space.
• 3-Row and 4-Row Coil Options — Capacity and water-side pressure drop tuned to the plant, with two-pipe and four-pipe versions to match the riser design.
• Enlarged Drain Pan Option — Available where the void is tight or the finished surface below is sensitive to condensate.
• Multi-Direction Filter Extraction — Service access is achievable whatever the installed void geometry, which protects the maintenance strategy.
• Seven-Speed DC with V8 and Modbus — Commissioning balance, up to 30% lower fan energy, and native integration for mixed fan coil and VRF designs.
• AEH Option — Electric auxiliary heating where the heating source is not water-based.

Where duct routes are short and direct, the AC range is the conventional selection and its on-site left/right piping reversal is a genuine design tolerance rather than a convenience. Where duct layouts are branched, long or not yet fixed, or where the specification carries an energy target, the DC inverter brushless range is the stronger choice: external static pressure selectable at 12/30/50Pa through the PCB or wired controller, seven speeds for balancing, up to 30% lower fan energy, and native V8 integration for combined fan coil and VRF designs. Coil options, connections, section height envelope and service access are shared, so the hydraulic and ceiling drawings are unaffected by the motor tier.

1. Concealed Office Ceilings — Hidden terminals preserve the ceiling line across open-plan and cellular floors; selectable ESP copes with partitioned layouts.
2. Hotel Guestroom Ducted Design — Quiet DC operation above the corridor ceiling with filter access from the room side.
3. Retail Units Behind Bulkheads — Multi-branch ducting serves sales areas from concealed positions with a single schedule line.
4. Apartments and Serviced Suites — Reversible connections and two return configurations cover varied unit layouts from one specification entry.
5. Hospitals and Clinics — Four-row coil options, low sound pressure and accessible filtration suit clinical and diagnostic spaces.
