MECO
The slim conceal type fan coil unit is designed for recessed installation in wall cavities, ceiling spaces, or under-window recesses, delivering vertical or frontal airflow while remaining hidden behind decorative panels. With a body thickness of 145 mm for the conceal version, this unit fits into narrow installation spaces where standard fan coil units cannot be accommodated. Manufactured by MECO, the series includes four models covering air volumes from 300 to 600 m³/h, suitable for various room sizes in commercial and public buildings. Each unit comes with a brushless DC motor as standard configuration and supports thermostat control for precise temperature adjustment. The dual air outlet design (upper and frontal) allows project designers to select airflow direction based on interior layout requirements.
Each unit is equipped with two drain pans installed on opposite sides, supporting both vertical and horizontal mounting orientations. This design eliminates the need to order separate models for different installation directions, which helps reduce inventory pressure for commercial procurement teams. Condensate drainage outlets are present on both sides of the vertical slim conceal unit; during installation, only the unused side outlet requires sealing.
All models are fitted with brushless DC motors as standard, operating on a 220V, 50Hz, 1-phase power supply. The motor provides three fan speed settings — high, medium, and low — allowing occupants to adjust air volume and noise level according to occupancy patterns. The motor is compatible with standard thermostat controllers, enabling integration into building automation systems.
The return air side filter is positioned for direct access without full unit disassembly, reducing maintenance time for facility management teams. The coil uses hydrophilic aluminum fin material paired with wear-resistant copper tubes, a configuration commonly specified in industrial applications for long operating life.
The water pipe connection side can be customized according to project requirements before shipment, which simplifies on-site installation work and reduces dependence on specific inventory SKUs. The unit supports two primary installation methods: horizontal mounting in suspended ceilings, or vertical concealment in wall cavities or under-window recesses with decorative grilles. Both decorative and conceal casing dimensions are available to match different architectural specifications. All water connections use standard ZG1/2" threaded ports for inlet and outlet, compatible with most HVAC piping systems. The maximum working pressure rating is 1.6 MPa, and the condensate water pipe diameter measures 21 mm.

The slim conceal fan coil unit is specified for interior spaces where visible HVAC equipment conflicts with decorative design requirements. Typical installation locations include under windowsills, within wall recesses, and in ceiling voids with decorative panel finishes. Common project types include conference rooms, hotel corridors, office lobbies, sports venues, and retail spaces where architects require unobtrusive air distribution. The dual air outlet configuration allows engineers to select upper discharge for perimeter heating applications or frontal discharge for general space cooling, adapting to different seasonal operation modes.
The conceal version measures 145 mm in thickness and 515 mm in depth, requiring a wall cavity or ceiling plenum of at least those dimensions to accommodate the unit and service clearance.
The pipe connection orientation is configured at the factory based on order specifications. Customization requests should be submitted during the procurement stage to ensure the correct configuration is shipped.
The unit supports thermostat control as a functional feature. Controller selection and supply are typically handled separately according to project control system requirements.
The unit is designed for two-pipe chilled and hot water systems with a maximum working pressure of 1.6 MPa, using standard ZG1/2" threaded connections.
