Midea compact four way cassette FCU for retrofit rollouts 575 575mm body drops into 585mm grids 400 600 CFM DC from 5W OEM ODM via Hongtai

Retrofit programmes and multi-site rollouts live or die on standardisation: every site that needs a different unit multiplies procurement lines, training, spares and risk. The Midea Compact Four-way Cassette Fan Coil Unit is sized to be the single answer — a 575×575mm body that drops straight into the standard 585mm ceiling grid used in commercial buildings worldwide. No grid cutting, no custom framing, no ceiling patching, and no rework contingency sitting in your budget. With 400–600 CFM and cooling capacities from 2.98 to 4.78 kW across the AC and DC range, it covers the small-to-medium zones — meeting rooms, guestrooms, clinics, small offices — that make up most retrofit schedules of rates.

At 204mm body height — just 198mm on 3rd Generation DC models — the unit clears shallow ceiling voids that defeat standard cassettes, so older buildings stay inside the programme instead of becoming exceptions with their own supply chain. The 500mm drain pump (1200mm on 3rd Gen) removes condensate without slope work or structural drainage changes, and the integrated safety mesh protects technicians during filter service, keeping safety audits clean across every site. The standard 360° panel delivers even air distribution with no vane balancing at commissioning — fewer labour hours per unit across the whole rollout.

The DC inverter brushless version draws as little as 5W at low speed and cuts fan energy by up to 30% — the lifecycle-cost line that makes whole-floor replacement proposals easy for landlords to approve. Seven fan speeds via the KJR-75A controller tune each room at handover, and 2-pipe or 4-pipe factory versions match whatever hydraulics each existing building gives you. All models run on 220–240V / 1Ph / 50Hz and carry the CE / Eurovent / ERP / RoHS / GB/T 19232 certification set; Hongtai supports chain-wide rollouts with OEM/ODM customisation — custom voltages from 180–440V at 50/60Hz, project branding, and Modbus/BACnet protocols — plus steady spare-parts supply across the contract period.

• 575 × 575mm Drop-In Dimensions — Fits standard 585mm ceiling grids worldwide; rework contingency comes out of the retrofit budget.
• 204mm / 198mm Shallow-Void Height — Older buildings with tight ceiling spaces stay inside the standard programme.
• One SKU Across Every Site — Simplified procurement, installer training and spare-parts holding for multi-site contracts.
• 500mm / 1200mm Drain Pump as Standard — Condensate handled with no drainage accessories to source per site.
• Integrated Safety Mesh — Protects technicians during filter service; keeps safety audits clean across the estate.
• DC from 5W Low-Speed Draw — Up to 30% fan energy saving; the lifecycle numbers that get landlord approval.
• 2-Pipe and 4-Pipe Versions — Match existing hydraulics across a whole portfolio without site modification.
• OEM/ODM Rollout Support via Hongtai — Custom voltage, branding and protocols plus spare-parts continuity for the contract period.

For like-for-like replacements where the budget is fixed by an insurance claim or a tight refurbishment allowance, AC keeps unit cost low and spares universal. For whole-floor or whole-portfolio replacements quoted to an owner who will live with the energy bills, the DC inverter brushless version is the stronger submission: from 5W at low speed, up to 30% less fan energy, seven speeds via the KJR-75A, and 198mm height on 3rd Generation models for the shallowest voids. Dimensions, grid fit and pipe connections are identical, so both motor tiers can be mixed across a rollout without splitting procurement or spares.

1. Office Suite Refurbishments — Drop-in replacement keeps tenant disruption measured in hours, not days.
2. Hotel Guestroom Renovations — Compact height fits shallow bathroom-lobby ceilings; quiet DC operation protects guest experience.
3. Clinics and Treatment Rooms — Safety mesh and low-noise DC models suit healthcare compliance regimes.
4. Meeting Rooms and Small Offices — Right-sized 400–600 CFM capacity avoids over-conditioning small zones.
5. Franchise and Chain Fit-Outs — One standardised unit across every site simplifies procurement, training and spares holding.
