Compact Horizontal Concealed Duct Type Fan Coil Unit

Product Overview of Horizontal Concealed Fan Coil Unit

This horizontal concealed duct type fan coil unit is engineered for ceiling-mounted installation in commercial and residential buildings where space is limited. With a body thickness of 200 mm, the unit fits within shallow ceiling cavities while delivering ducted air distribution. The product line includes nine models (DCV-MFP-34WA-E through DCV-MFP-158WA-E) with airflow ranging from 340 to 1500 m³/h at high speed, covering cooling loads from 2000 W to 12500 W total heat. External static pressure is rated at 12 Pa standard with a 30 Pa optional configuration for extended ductwork.

Design and Construction of Concealed Duct FCU

200 mm Slim Body Profile

The unit measures 200 mm in height across all nine models, reducing the required ceiling plenum depth compared to standard horizontal fan coil units. The low-profile design supports installation in renovation projects and new construction with limited vertical ceiling space. Net length ranges from 700 mm to 1300 mm depending on capacity grade.

Reversible Water Connection Sides

The left and right water pipe connection orientation can be specified during ordering. This feature allows installers to match existing piping layouts without re-routing hydronic lines, reducing on-site modification work for commercial procurement projects. All water connections use ZG3/4" threaded ports.

Plastic Fan Blade Assembly

The centrifugal fan assembly uses plastic blades engineered for smoother airflow delivery and reduced operating noise compared to metal blade alternatives. Each unit is fitted with multiple fan wheels corresponding to its capacity size, driven by a single DC brushless motor.

DC Brushless Motor System

All models are equipped with DC brushless motors. Power input at high speed ranges from 21 W (34WA-E) to 85 W (158WA-E). The motor supports three-speed operation (high, medium, low) for capacity adjustment based on occupancy and load conditions.

Optional Drain Water Pump

A drain water pump is available as an optional accessory for installations where gravity condensate drainage is not achievable. The standard condensate drain connection measures ø26 mm in diameter.

Performance Characteristics for Commercial Applications

Airflow and Static Pressure

Air volume ranges from 340 m³/h to 1500 m³/h at high speed, with medium and low speed values proportionally reduced. Standard external static pressure is 12 Pa; the 30 Pa option is available for projects requiring longer duct runs or multiple diffusers.

Cooling and Heating Output

Total cooling capacity spans from 2000 W to 12500 W (high speed, total heat) across the model range. Sensible cooling and heating capacity values are listed in the specification table. All ratings are based on standard air and water entry temperature conditions.

Noise Levels

High-speed sound pressure levels range from 31 dB(A) (smallest model) to 48 dB(A) (largest model). The plastic blade design contributes to lower tonal noise compared to conventional metal fan assemblies.

Hydronic Specifications

The coil assembly uses hydrophilic aluminum fins and copper tubes with a maximum working pressure rating of 1.6 MPa. Waterflow volume at high speed ranges from 0.34 m³/h to 1.44 m³/h, with pressure dropping from 14 kPa to 40 kPa across the model line.

Typical Applications in Commercial and Institutional Buildings

This horizontal concealed fan coil unit is specified for a range of commercial applications including hotel guest rooms, hospital wards, office buildings, classroom spaces, retail areas, and multi-unit residential buildings. The concealed ceiling installation preserves interior design aesthetics, while the ducted configuration allows flexible air outlet placement per room layout requirements.

Technical Specifications

FAQ About Concealed FCU

What is the body thickness of this fan coil unit?

All nine models share a uniform body height of 200 mm, allowing consistent ceiling detail design across different capacity zones of a building.

Can the water pipe connection side be customized?

Yes, left-side or right-side water piping orientation can be specified at the time of ordering to match project piping layouts.

Is the drain water pump included as standard?

No, the drain water pump is an optional component. Standard units rely on gravity drainage through the ø26 mm drain connection.

What external static pressure options are available?

The standard configuration provides 12 Pa external static pressure. A 30 Pa option is available for projects requiring longer duct runs.

How many fan speed settings are supported?

Each unit operates at three selectable speeds: high, medium, and low. Corresponding airflow and capacity values are listed in the specification table.
