If you are interested in selecting and purchasing a ducted fan coil unit (also known as a duct fan coil) to provide the cooling and heating system for your project or building, with suitable quality and pricing, stay with us as we explore the technical specifications, available capacities, and how to choose the right ducted fan coil unit.

Ducted Fan Coil Unit Experts' Buying Guide and Price List

Ducted fan coil units, also known as duct fan coils or ducted FCUs, are a type of fan coil unit typically installed in the false ceiling or other concealed areas of buildings. They distribute conditioned air to the desired spaces through ductwork.

In general, ducted fan coil units are available in a wide range of capacities, from 600 CFM to 3000 CFM, in two types: rear air return or bottom air return (horizontal and vertical models). They are also designed to allow the intake of fresh air, and are manufactured under various Iranian and international brands.

Due to their high air delivery capacity, ducted fan coils are commonly used in large spaces such as sports halls, hotel lobbies, medical center lobbies, cinemas, building lobbies, and more, to ensure a suitable indoor temperature as part of the HVAC system.

Ducted Fan Coil Unit Advantages

Ducted fan coil units are a suitable option for air conditioning buildings that need uniform air distribution, reduced piping for the cooling and heating system, environmental beauty, and energy savings. The advantages of ducted fan coil units are:

• Uniform air distribution: Ducted fan coil units distribute cold or hot air evenly throughout all spaces and prevent the creation of hot or cold spots in the environment due to the use of ductwork.
  
  
• Possibility of hidden installation and maintaining the appearance: These systems are usually installed in false ceilings or hidden spaces, so they do not affect the interior decoration, and the aesthetic appearance of the environment is preserved.
  
  
• Reduced noise and operating sound: Due to installation in ceiling spaces and the use of ducts, the noise generated by the fan coil is minimized, creating a quiet environment for residents or employees.
  
  
• Flexibility in design and implementation: Ducted fan coil units can be implemented in various buildings and with different designs. It is possible to choose the appropriate capacity for each space and also adjust the temperature for different areas.
  
  
• Increased indoor air quality: In ducted fan coil units, it is possible to install various air filtration filters, which improve the quality of incoming air, reduce dust, and prevent pollutants from entering the indoor environment.
  
  
• Possibility of connection to smart systems: Some advanced models of ducted fan coil units have the ability to connect to building management systems (BMS), which helps to better control the temperature and reduce energy consumption.
  
  

Ducted Fan Coil Unit Types Based on Static Pressure of the Blower Fan

Ducted fan coil units are classified into three main categories based on static pressure:

• Low Static Pressure
• Medium Static Pressure
• High Static Pressure

Static pressure refers to the force exerted by the unit’s blower fan to overcome the resistance of the ductwork system and ensure proper air distribution. The longer and more complex the duct layout, the stronger the fan required, meaning a higher static pressure is needed.

Below, we will explain each of these categories in detail.

1. LSP Ducted Fan Coil Unit

Low static pressure ducted fan coils are designed for small and medium spaces that require short ductwork.

This type of ducted fan coil, due to its low static pressure, is usually used in residential buildings, small offices, and spaces that require simple air distribution.

Since the fan power in low static pressure ducted fan coils is less than other models, these fan coils have low energy consumption and produce little noise, but they are not suitable for large spaces or long ductwork.

LSP Ducted Fan Coil Unit Features:

• Fan static pressure between 10 and 50 Pascal
• Suitable for small and medium spaces
• Requires short and simple ductwork
• Low noise level
  
  

LSP Ducted Fan Coil Unit Advantages:

• Low energy consumption
• Easy installation and lower cost
• Low noise and quiet operation
  
  

LSP Ducted Fan Coil Unit Disadvantages:

• Limitations in ductwork length
• Inability to provide sufficient air for large spaces
  
  

2. MSP Ducted Fan Coil Unit

Medium static pressure ducted fan coils are more suitable for office buildings, commercial buildings, hotels, and stores that require medium ductwork.

The higher static pressure of this type of ducted fan coil compared to the low-pressure model allows for better and more uniform air distribution inside the space.

Medium static pressure ducted fan coils strike a good balance between energy consumption, air distribution capacity, and noise level, making them a practical option for medium-sized spaces.

MSP Ducted Fan Coil Unit Features:

• Static pressure between 50 and 150 Pascal
• Suitable for office buildings, commercial buildings, and hotels
• Possibility of better and more uniform air distribution
• Ability to install in false ceilings with medium ductwork
  
  

MSP Ducted Fan Coil Unit Advantages:

• Possibility of longer ductwork compared to the low-pressure model
• More uniform air distribution
• Suitable for medium-sized spaces
  
  

MSP Ducted Fan Coil Unit Disadvantages:

• Higher energy consumption compared to the low-pressure model
• Higher noise production
  
  

3. HSP Ducted Fan Coil Unit

High static pressure ducted fan coils, or high pressure, are more suitable for large buildings, hospitals, conference halls, and shopping malls that require extensive air distribution.

Due to the high static pressure, it allows the use of long and complex ductwork. High static pressure ducted fan coils have a stronger motor and fan, so they distribute more air in the space, but they also have higher energy consumption and noise levels.

HSP Ducted Fan Coil Unit Features:

• Static pressure over 150 Pascal (usually between 150 and 300 Pascal)
• Suitable for large buildings and public spaces
• Possibility of using long and complex ductwork
• Stronger motor and fan for more air distribution
  
  

HSP Ducted Fan Coil Unit Advantages:

• Possibility of air distribution in large spaces
• Ability to connect to multiple air distribution vents
• High-performance power
  
  

HSP Ducted Fan Coil Unit Disadvantages:

• High energy consumption
• Higher noise production
• Higher installation and maintenance costs
  
  

Ducted FCU Vs. Concealed Ceiling FCU

The difference between ducted fan coil and concealed ceiling fan coil is in their air distribution method, capacity, and installation:

• Capacity: Concealed ceiling fan coil units are usually used in lower capacities (200 to 1,200 CFM) for smaller spaces such as residential units, hotel rooms, and office spaces.
  
  In contrast, ducted fan coils with higher capacities (600 to 3,000 CFM) distribute conditioned air to multiple spaces through ductwork and are more commonly used in large buildings, hotel lobbies, commercial centers, and hospitals.
  
  
• Installation and Air Distribution: Concealed ceiling fan coil units usually do not require ductwork, but in some cases, they can be connected to short and limited ducts. This type of fan coil is installed directly inside the false ceiling and distributes air directly into the space through one or two vents.
  
  Although it does not require an extensive ductwork system compared to ducted fan coils, in some applications, a short duct may be used for multiple vents for better air distribution. In contrast, ducted fan coils must have ductwork to deliver conditioned air to multiple points in a building.

Factors to Keep in Mind When Buying a Ducted Fan Coil Unit

Some important points to consider when selecting and purchasing ducted fan coils include the following:

• The working pressure of the water coil in ducted fan coils is based on a working pressure of 8 bar, which is suitable for buildings up to 20 stories.
• Considering the possibility of manufacturing ducted fan coils with higher working pressures customized for buildings over 20 stories, if your building height exceeds this amount, be sure to discuss the matter with the sales experts at DamaTajhiz HVAC.
• Static working pressure of the air-handling fan of the ducted fan coil (low, medium, high).
• Type of air intake for the ducted fan coil (from below or from the back).
• Before purchasing and ordering various types of ducted fan coils, ensure the orientation of the cold and hot water inlet and outlet pipes to the fan coil (left or right), the type of device, air return as "intake from below" or "intake from the back," and the possibility of fresh air intake.
