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.
For like-for-like replacements where the budget is fixed by an insurance claim or a tight refurbishment schedule, AC keeps the swap simple and economical. For whole-floor replacements quoted to an owner who will live with the energy bills, the DC inverter brushless version is the stronger tender: 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 crews install both the same way.
Yes. The 575×575mm body is sized to drop straight into the standard 585mm grid used in commercial buildings worldwide — no grid cutting, no framing, no ceiling patching.
It is designed for exactly that. Pull the old unit, drop this one into the same opening, reconnect the pipes and drain, and commission. Most swaps complete the same day with zero ceiling rework.
The body is 204mm high — 198mm on 3rd Generation DC models — which clears shallow voids that defeat standard cassettes. Always confirm hanger and service clearances against the installation manual.
Yes — a 500mm-lift pump is standard, raised to 1200mm on 3rd Generation DC models, so condensate is handled without slope work or structural drainage changes.
The DC range runs from 30 dB(A) at high speed down to near-inaudible levels on lower speeds — quiet enough for hotel guestrooms, clinics and meeting rooms.
