Fan coil units (FCU) are the terminal devices of every chilled-water air conditioning system: a coil and a quiet fan that condition each room individually in hotels, hospitals, offices and residential towers.
The factory-direct FP series covers airflow from 340 to 2,380 m³/h with duct, cassette, ceiling & floor, floor standing and wall-mounted configurations — compatible with all chiller systems as the terminal equipment.
Cassette fan coils are rated at 7 °C entering chilled water with air at 27 °C DB/19 °C WB; casings are IP24 rated with DN20 water and DN25 drain connections.
- FP-34 to FP-238: airflow 340–2,380 m³/h, cooling 1.8–12.6 kW per unit
- Duct, cassette, floor-ceiling, floor standing and wall-mounted types
- Three-speed quiet motors; 2-pipe and 4-pipe coil options
- 7–12 °C chilled water, 40–60 °C hot water compatible
- OEM projects and custom specifications welcome — own factory
- Large stock and short delivery time for project quantities

What is the difference between 2-pipe and 4-pipe fan coil units?
A 2-pipe fan coil has one coil and one water circuit, so the whole building heats or cools in the same mode. A 4-pipe unit carries separate chilled-water and hot-water coils for simultaneous room-by-room heating and cooling. Our CSQ 600–1,000 CFM cassette family illustrates the split: the 2-pipe version delivers 5.3–10.0 kW cooling, while the 4-pipe version pairs 4.5–5.8 kW cooling with 8.5–13.0 kW heating.
What water temperatures do fan coil units accept?
FP series ducted fan coils are designed for 7–12 °C chilled water and 40–60 °C hot water. CSQ cassette models are rated at 7 °C entering chilled water with a 5 °C temperature rise, tested with air at 27 °C DB/19 °C WB; the 4-pipe heating coil is rated at 65 °C entering water with a 10 °C drop.
What is the MOQ for fan coil units, and is OEM possible?
Fan coil orders can start from a single trial unit for first-time buyers, and project quantities are quoted with tiered pricing. OEM and ODM manufacturing — cabinet colour, badging and packaging to your brand standard — is available from our own ISO 9001 factory. Send a load list or floor plan and our team returns a selection and quotation, usually within 24 hours.
How noisy are cassette fan coils?
The compact CSQ4 cassette with a 650 × 650 mm panel measures around 43 dB(A) at high fan speed, while the larger 600–1,000 CFM four-way cassettes range from 40 to 53 dB(A) depending on size and speed. All models use three-speed motors, so low-speed night operation runs several dB(A) below the rated high-speed figures.
