Midea Compact Cassette FCU Retrofit 204mm Deep No Rework DC Compact Cassette FCU 5W Low Speed 30 Fan Saving

Refurbishment and tenant fit-out projects are where terminal unit selections are most often reopened, because the existing ceiling module rarely matches the drawing set. The Midea Compact Four-way Cassette Fan Coil Unit is dimensioned for that reality: a 575×575mm body that drops into the standard 585mm ceiling grid used in commercial buildings worldwide, with no grid cutting, no bespoke framing and no ceiling patching. Across the combined AC and DC range it covers 400–600 CFM and 2.98–4.78 kW of cooling — the small-to-medium zone band that dominates refurbishment schedules — and Eurovent-certified figures allow a like-for-like replacement to be specified on performance.

The section is where this unit earns its place on a design drawing: 204mm body height, reduced to 198mm on 3rd Generation DC models, clears the shallow slab-to-slab zones in older buildings that rule out standard cassettes. The 500mm condensate lift pump — 1200mm on 3rd Generation DC — removes drainage fall from the coordination problem, and the integrated safety mesh protects maintenance staff during filter service without adding a removable guard to the specification. A standard 360° panel provides even distribution with no vane balancing at commissioning, and the two-row coil, G3/4" connections and 1.6 MPa maximum working pressure sit within normal chilled and low-temperature hot water practice. Factory two-pipe and four-pipe versions match the existing hydraulics, and an electric auxiliary heating option is available.

For whole-floor replacement strategies the DC inverter brushless version is the stronger line in the report: a minimum draw of 5W at low speed, up to 30% lower fan energy and sound pressure from 30 dB(A), with seven speeds through the KJR-75A controller for room-by-room balance at handover. All models run on 220–240V / 1Ph / 50Hz. Hongtai supports multi-site and chain-wide programmes with OEM/ODM customisation — custom voltages from 180–440V at 50/60Hz, project branding, and Modbus or BACnet protocols — so a standard specification can be applied across a portfolio without a separate approval route in each country.

• 575 × 575mm Within a 585mm Grid — Fits the standard ceiling module without cutting, framing or patching; the replacement stays a replacement.
• 204mm / 198mm Section Depth — Clears shallow slab-to-slab zones in existing buildings where standard cassettes cannot be scheduled.
• 500mm / 1200mm Lift Pump — Removes drainage fall from the coordination problem; no structural drainage alteration.
• Standard 360° Panel — Even distribution without vane balancing, reducing commissioning tasks per unit.
• Integrated Safety Mesh — Protects maintenance staff during filter service without a separate guard item in the specification.
• DC from 5W at Low Speed — Up to 30% lower fan energy supports whole-floor replacement cases and energy-audit reporting.
• 2-Pipe and 4-Pipe Factory Versions — Matches the existing riser arrangement without site adaptation.
• AEH Option — Electric auxiliary heating available where the existing heating source is not water-based.
• OEM/ODM Programme Support via Hongtai — Custom voltage, branding and protocols with spare-parts continuity across multi-site contracts.

Where the replacement is defined by an insurance settlement or a fixed refurbishment budget, the AC three-speed version keeps the intervention simple and the unit rate low, with a control philosophy that matches whatever the building already has. Where the design is being reported against an energy target, or the landlord will carry the running cost for a decade, the DC inverter brushless version is the better case: 5W at low speed, up to 30% lower fan energy, seven speeds through the KJR-75A controller and 198mm section depth on 3rd Generation models for the tightest voids. Dimensions, grid fit, connections and panel are identical, so the hydraulic and ceiling drawings do not change with the motor tier.

1. Office Suite Refurbishment — Drop-in replacement keeps tenant downtime measured in hours; the existing ceiling module is reused.
2. Hotel Guestroom Renovation — Compact section depth suits shallow bathroom and lobby ceilings; the DC tier supports guestroom acoustic criteria.
3. Clinics and Treatment Rooms — Safety mesh and low sound pressure support healthcare maintenance and acoustic requirements.
4. Meeting Rooms and Cellular Offices — Right-sized 400–600 CFM band avoids over-conditioning small zones and short-cycling.
5. Chain and Franchise Fit-Out — One standardised unit across every site simplifies the specification, the spares holding and the O&M documentation.
