Fan Coil Units — selection guide
The Fan Coil Units category currently lists 44 models, maximum airflow 340–2,380 m³/h, on AC motors, across 9 series. Common voltages: 220 V.
Fan coil units are chilled- or hot-water terminal units for hotels, offices, hospitals and residential systems: horizontal or vertical, exposed or concealed, and four-way cassette types with 340–2,380 m³/h airflow and 220 V single-phase motors.
How to select a Fan Coil Unit
- Select by cooling / heating capacity at the water temperatures of the system and by airflow at medium speed.
- Concealed units need external static pressure for the duct and grille; check the ESP rating.
- Cassette units suit open-plan spaces with suspended ceilings; exposed units where there is no ceiling void.
- Specify three-speed or EC motor and the control valve / thermostat interface.
Typical applications
- Hotel rooms and offices
- Hospitals and schools
- Residential chilled-water systems
Why specify LONGWELL fan coil units
Every model here is a current production item with structured data — not a catalogue scan. Curves are tested on our own wind-tunnel rigs per AMCA 210 / ISO 5801 methods, drawings and datasheets download directly, CAD is released on request, and a quotation with the duty-point check comes back within one business day. Samples ship in 1–3 days and production batches in 15–30 days from the factory in Ningbo, with ISO 9001 / 14001 / 45001 management systems and ETL, CE and RoHS documentation per product line.
FAQs — Fan Coil Units
How do I size a fan coil unit?
From the room cooling load at design water temperatures, then check that the airflow at medium speed gives acceptable air distribution and noise. Our engineers can provide the capacity table for your water conditions.
What external static pressure do concealed units provide?
Concealed units are rated for duct and grille resistance; the value depends on the size and is stated in the model data. For long duct runs ask for the high-ESP version.
Are EC motors available?
Yes, EC motor versions with 0–10 V control are available for lower consumption and finer room control.
