MFP-136WA-B
MECO
The MFP-136WA-B horizontal air blowing duct type fan coil unit serves as a concealed ceiling-mounted terminal device for central air conditioning systems. Designed for integration with ductwork, this unit delivers conditioned air to multiple rooms or zones through connected air ducts. The model operates with three selectable static pressure settings — 12Pa, 30Pa, and 50Pa — allowing specification matching to different duct lengths and layout configurations. This ducted configuration supports uniform air distribution across larger floor areas, making it suitable for office floors, hotel guest room corridors, retail spaces, and hospital wards where concealed installation and extended duct runs are required.

The heat exchanger assembly uses purple copper tubes paired with aluminum fins. Fin spacing is optimized through computer simulation and empirical testing to balance heat exchange surface area and air passage resistance. Purple copper tubing provides mechanical strength for withstanding water pressure in high-rise building installations. The coil design supports both chilled water cooling and hot water heating operation within standard HVAC system temperature ranges.
Each fan assembly undergoes dynamic balancing calibration during production. The centrifugal fan configuration draws return air through the coil and discharges it into the supply duct connection. The motor winding specifications correspond to the 134W power rating at 12Pa static pressure, with adjusted power draw at higher static pressure settings.
The unit casing is fabricated from tensile steel sheet with a plastic-sprayed surface finish. The drain pan uses one-piece press forming without welded seams, reducing potential leakage points. Insulation material is applied to the drain pan surface to manage condensate formation and prevent secondary water drippage. The flat pan design supports condensate drainage through the connected drain line.
The three selectable static pressure options (12Pa, 30Pa, 50Pa) enable HVAC designers to match unit performance to specific ductwork designs. Lower static pressure settings apply to short duct runs with minimal fittings, while higher settings accommodate longer duct networks with additional elbows and branches. This adjustability reduces the need for specifying different unit models across varying zones of a single project.
The unit supports interface connection with Modbus protocol-based building management systems (BMS). This compatibility allows centralized monitoring and control alongside other HVAC equipment in commercial facilities. The Modbus connectivity supports standard supervisory system platforms commonly deployed in office buildings, hotels, and healthcare facilities.
Stainless steel flexible hoses can be fitted for inlet and outlet water connections. These hoses accommodate minor misalignment between unit piping and building water lines during installation, and reduce vibration transmission from the unit to the fixed pipework.
The ducted fan coil unit installs above suspended ceilings with only supply and return grilles visible in the finished space. Common installation projects include multi-story office buildings, mid-range and luxury hotel properties, shopping mall tenant areas, hospital inpatient departments, and educational facility classrooms. The concealed design supports interior design requirements where exposed equipment is not desired.
Both inlet and outlet water connections use ZG3/4" threaded ports. Installers should match this connection size with the building chilled and hot water pipework.
Yes, the unit supports Modbus protocol interface for integration with standard building management and supervisory control systems used in commercial facilities.
The horizontal ducted design requires sufficient plenum space above the suspended ceiling for the unit body, duct connections, and water piping access. Specific clearance dimensions follow the product installation drawing specifications.
Stainless steel flexible hoses for water connections are available as an optional accessory and can be specified at the time of order.
