Midea Compact Cassette FCU Drops Straight Into 585mm Grids Swap ReadyZero Ceiling Grid Rework Needed

Refurbishment and tenant fit-out work is where margins go to die: the old unit comes out, the grid turns out to be an odd size, and a one-day swap becomes three. The Midea Compact Four-way Cassette Fan Coil Unit is sized to end that story — 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 custom framing, no ceiling patching. 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 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, often the difference between winning and walking away from older buildings. The 500mm drain pump (1200mm on 3rd Gen) removes condensate without slope work or structural drainage changes, and the integrated safety mesh protects your technicians during filter service, keeping site safety audits clean. The standard 360° panel delivers even air distribution with no vane balancing time at commissioning — one less task per unit before sign-off.

The DC inverter brushless version draws as little as 5W at low speed and cuts fan energy by up to 30% — a persuasive line item when quoting whole-floor replacements to cost-conscious landlords. Seven fan speeds via the KJR-75A controller let you tune each room at handover, 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 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.
