Midea compact four way cassette FCU drops into 585mm grids for same day replacement body 204mm profile DC from 5W OEM ODM via Hongtai

Every facility manager inherits them sooner or later: a fleet of ageing cassettes reaching end of life in an occupied building, where every replacement means tenant disruption, ceiling work and complaint risk. The Midea Compact Four-way Cassette Fan Coil Unit is sized to make the replacement programme painless — a 575×575mm body that drops straight into the standard 585mm ceiling grid used in commercial buildings worldwide. Pull the old unit, drop this one in, reconnect, commission. No grid cutting, no framing, no ceiling patching, no follow-up repairs. 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, office suites — that dominate any replacement schedule.

At 204mm body height — just 198mm on 3rd Generation DC models — the unit clears the shallow ceiling voids typical of older building stock, so modernisation reaches floors that standard cassettes cannot serve. The 500mm drain pump (1200mm on 3rd Gen) removes condensate positively, keeping leaks and the ceiling repairs they trigger off your work-order list. The integrated safety mesh protects your technicians during filter service, keeping site safety audits clean. And the standard 360° panel delivers even, draught-free air distribution with no vane balancing after the swap — one less reason for occupants to call.

The DC inverter brushless version draws as little as 5W at low speed and cuts fan energy by up to 30% — the payback line that makes whole-floor replacement budgets easier to approve. Seven fan speeds via the KJR-75A controller let your team tune each room at handback, and 2-pipe or 4-pipe factory versions match whatever hydraulics the existing building gives you. All models run on 220–240V / 1Ph / 50Hz, and Hongtai supports multi-year, multi-site replacement programmes 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 with zero rework; same-day swaps keep tenants in place.
• 204mm / 198mm Shallow-Void Height — Modernises older buildings whose tight voids defeat standard cassettes.
• 500mm / 1200mm Drain Pump — Positive condensate removal keeps leaks and ceiling repairs off the work-order list.
• Integrated Safety Mesh — Protects technicians during filter service; supports clean site safety audits.
• Standard 360° Panel — Even, draught-free distribution with no vane balancing after each swap.
• DC From 5W Low-Speed Draw — Up to 30% energy saving builds the payback case for whole-floor replacement.
• 2-Pipe and 4-Pipe Versions — Match existing hydraulics in any retrofit without plant-room changes.
• OEM/ODM Rollout Support via Hongtai — Custom voltage, branding and protocols plus spare-parts continuity for multi-site contracts.

For like-for-like swaps under fixed maintenance budgets, the AC version keeps unit cost low and the job simple. For whole-floor or whole-building replacement programmes that must be defended to finance, the DC inverter brushless version is the stronger case: 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 your team services both versions with the same routine and the same spares.

1. Occupied Office Floor Refurbishment — Same-day swaps keep tenants working; disruption measured in hours, not days.
2. Hotel Guestroom Upgrades — Compact height fits shallow bathroom-lobby ceilings; quiet DC operation protects guest satisfaction.
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. Multi-Site Retail and Franchise Estates — One standardised unit across every site simplifies training and spares holding.
