MECO
The one-way air blowing cassette type fan coil unit is a ceiling-mounted terminal for chilled water central air conditioning systems. Designed for recessed installation along ceiling perimeters, this 2-pipe configuration delivers directional single-side airflow with a unit body thickness of 235mm. Manufactured by MECO, the product line carries ISO 9001 and CE certification and covers four capacity sizes for different room load requirements. The unit integrates a drain pump as standard, expanding installation flexibility in projects with constrained ceiling space.

With a body height of 235mm, this unit fits into shallow ceiling plenum spaces where deeper cassette units cannot be installed. The single-side air discharge pattern suits perimeter mounting, directing conditioned air from the wall edge into the occupied zone. The flush panel integrates visually with standard suspended ceiling systems without occupying floor or wall area.
Auto-swing louvers adjust the vertical discharge angle automatically across three fan speeds. Horizontal air guide vanes can be repositioned manually for fine-tuned airflow direction. Each unit ships with an infrared remote controller as standard; a wired wall controller is available as an optional accessory for grouped control in commercial procurement projects.
An integrated condensate pump provides 750mm of drainage lift, which removes elevation constraints on condensate piping runs. A float switch inside the drain pan interrupts fan operation when water reaches the threshold level, preventing overflow events. Fresh air intake connection is available on all models to support mechanical ventilation requirements.
Testing conditions: Cooling — entering air dry bulb 27°C, wet bulb 19.5°C; chilled water in 7°C / out 12°C. Heating — entering air dry bulb 20°C; hot water in 60°C, same flow rate as cooling mode.
Along exterior walls of office buildings and glass-fronted retail spaces, the single-direction discharge pattern delivers conditioned air from the building envelope inward, addressing solar gain loads near windows. The slim cassette profile preserves ceiling aesthetics in reception areas, meeting rooms, and sales floors.
Restaurant dining areas, hotel lobbies, and corridor zones use these units for perimeter climate control. The flush-mounted panel integrates with standard ceiling grids, supporting interior design requirements in hospitality and public building projects. The remote control allows staff to adjust settings without accessing the ceiling cavity.
Left-side or right-side water pipe connection can be selected to match on-site piping layouts, reducing installation labor on retrofit and new construction projects. The unit supports Modbus protocol integration for connection to building management systems, enabling centralized monitoring across commercial facilities. An optional air purification module with negative ion generator can be specified for projects with enhanced indoor air quality requirements.
The unit body measures 235mm in height. Installers should reserve additional vertical space above the unit for water piping, condensate line routing, and electrical connections. The decorative panel sits flush with the finished ceiling surface.
Yes, a condensate drain pump is integrated as standard equipment, providing 750mm of water lift. A float switch is also built into the drain pan as a safety measure against water overflow.
A wired wall controller is available as an optional accessory. The standard configuration ships with an infrared remote controller. Wired controllers are typically specified for group control arrangements in commercial procurement and building management system integration projects.
