The 1-way cassette type fan coil unit serves as a ceiling-mounted terminal device for central air conditioning systems. Designed for recessed ceiling installation along perimeter walls, this unit delivers single-direction airflow while preserving floor and wall space. The 4-pipe configuration supports simultaneous cooling and heating operations, making it suitable for buildings with year-round climate control requirements. Each unit ships with a remote controller as standard and supports fresh air intake connection.
The unit body measures 236mm in height, allowing installation in ceilings with limited vertical clearance. The flat panel sits flush with the ceiling surface for a uniform visual appearance. With a unit weight starting at 22kg, the structure maintains a lightweight profile without compromising structural rigidity. The panel dimensions are 1044×468×31mm, covering the installation opening completely.
This 1-way cassette unit features auto-swing horizontal louvers that adjust the vertical air discharge angle automatically. Manual adjustment of the horizontal air guide bars is also available for directional airflow tuning. Three fan speed settings (High/Medium/Low) provide air volume ranging from 180 m³/h to 850 m³/h across four model sizes. A remote controller comes as standard equipment, and a wired controller is available as an optional accessory for group control scenarios.
An integrated drain pump provides a 750mm water lift, which extends installation flexibility and reduces constraints from condensate piping layout. A built-in float switch triggers a safety shutoff when condensate reaches a preset level, preventing water overflow incidents. The drain pipe connection measures Ø26mm, compatible with standard condensate piping systems.

Testing conditions: Cooling — entering air dry bulb 27°C, wet bulb 19.5°C; water in 7°C / water out 12°C. Heating — entering air 20°C; water in 60°C / water out 50°C.
Along exterior walls and perimeter zones of office buildings, the single-direction discharge pattern directs conditioned air toward interior spaces without creating drafts near windows. Retail stores and shopping malls use these units along display walls and glass facades, where the slim cassette profile preserves visual merchandising space.
Hotel corridors, restaurant dining areas, and hospital waiting areas benefit from the flush ceiling design, which maintains a clean interior aesthetic. The 4-pipe system supports individual room temperature adjustment throughout seasonal transitions, when some spaces require cooling while others need heating.
Left or right water pipe connection can be specified at the time of order, accommodating different piping layouts on site. The unit interfaces with most Modbus-based building management systems and proprietary supervisory protocols, allowing centralized monitoring and control across commercial facilities. An optional negative ion generator is available for projects requiring additional air treatment.
The unit body height is 236mm. Installers should allow additional clearance for water piping and electrical connections above the unit. The panel sits flush with the finished ceiling and requires a cutout matching the unit dimensions.
Yes, each unit includes a fresh air intake connection that allows introduction of outside air into the supply airstream, supporting ventilation requirements in commercial spaces.
A 4-pipe system contains separate cooling and heating coils, enabling simultaneous cooling and heating across different zones or rapid mode switching within the same space. A 2-pipe system uses a single coil for either cooling or heating, selected at the building level.
