GDTW Floor-Mounted Ducted Fan Coil Units, on the other hand, are floor-mounted systems equipped with a ducted air distribution design. This configuration allows conditioned air to be distributed evenly across larger areas through a duct network. They can be integrated with central air duct systems and provide more uniform temperature control in large-volume applications requiring higher capacities, making them an ideal choice for large production facilities and industrial plants.  

Thanks to their duct connection capability, the units can also be installed outside the conditioned area, with cooled or heated air delivered to the target space through air ducts. This provides a significant advantage for applications where the conditioned space is too limited to accommodate the equipment itself. 

In summary, GCW models offer a compact and localized climate control solution, while GDTW models are designed to provide centralized and uniform air distribution for larger spaces and industrial applications. 

FCU Series Fan Coil Units are widely used across a broad range of industrial applications thanks to their robust design, flexible configuration, and reliable performance.

Selecting the appropriate FCU Series Fan Coil Unit is essential to ensure efficient, reliable, and stable system operation. Key technical parameters such as capacity, airflow, and water temperatures should be carefully evaluated according to the specific requirements of the application. 

The main factors to consider include: 

• Cooling and heating capacity: The required capacity should be determined based on the size of the conditioned space and its total heating or cooling load to ensure optimal performance. 

• Airflow rate: The unit should provide sufficient airflow to achieve uniform air distribution and consistent temperature control throughout the space. 

• Water temperatures: System performance is directly influenced by the operating water temperatures. Typical design conditions are 6°C/12°C for cooling and 80°C/70°C for heating. Since the unit capacity varies with different water temperature conditions, these values should be verified during the selection process. 

• Installation space and model selection: The choice between a wall-mounted (GCW) or floor-mounted ducted (GDTW) model should be based on the available installation space, air distribution requirements, and the specific needs of the application. 

Careful evaluation of these criteria helps ensure that the selected FCU Series unit delivers maximum efficiency, reliable performance, and long-term operational stability.

FCU Series Fan Coil Units are designed to operate within centralized water-based HVAC systems, offering an energy-efficient solution for industrial climate control applications. In these systems, chilled or heated water is produced centrally and distributed to fan coil units, where conditioned air is delivered to the occupied spaces. This configuration enables more controlled and balanced energy management across the facility. 

The combination of optimized airflow and an efficient water circulation system helps minimize unnecessary energy consumption while maintaining the desired indoor conditions. In addition, the ability to provide independent temperature control for different zones allows energy to be used only where it is needed, improving overall system efficiency. This is particularly beneficial in large industrial facilities with varying operational requirements. 

Centralized fan coil systems may also offer advantages in terms of initial investment and total cost of ownership, depending on the size and design of the project. 

Overall, the FCU Series combines energy-efficient operation with operational flexibility, helping facilities optimize energy consumption and maintain operating costs under control over the long term. 

The installation process for an FCU Series Fan Coil Unit should be planned according to the selected model type and the specific requirements of the application. Wall-mounted units are installed directly onto the designated mounting surface, while ducted models require a properly designed air distribution duct system to ensure efficient and uniform airflow. 

During installation, the following factors should be carefully considered: 

• Water connections, condensate drainage, and electrical connections should be completed correctly and in accordance with applicable standards. 

• The airflow path must remain unobstructed to ensure optimal cooling or heating performance. 

• Adequate service and maintenance clearance should be provided to facilitate routine inspections and future maintenance activities. 

• The unit should be installed in an appropriate location that supports efficient air distribution and reliable system operation.

The performance of FCU Series Fan Coil Units may be affected by operating conditions and maintenance practices. Most issues are related to airflow, the water circuit, or system components and can be minimized through proper installation and regular preventive maintenance. 

Common issues and recommended solutions include: 

• Insufficient cooling or heating performance: If the desired room temperature cannot be achieved, the water flow rate may be inadequate or the coil surfaces may be contaminated. The water circuit should be inspected, the coils should be cleaned, and the system capacity should be verified to ensure it matches the application requirements. 

• Airflow problems: Uneven temperature distribution may result from clogged air filters or reduced fan motor performance. Cleaning or replacing the filters and inspecting the fan and motor assembly can help restore proper airflow and system efficiency. 

• Condensate and drainage issues: A blocked drain line or insufficient insulation may cause water accumulation, potentially reducing unit performance. The drainage system should be cleaned, and insulation should be checked and improved where necessary. 

• Irregular operation or system fluctuations: Sudden temperature variations or unstable performance may indicate issues with the control system, sensors, or water temperature conditions. Inspecting these components and optimizing system settings can help ensure stable operation. 

• Performance degradation due to inadequate maintenance: Failure to perform regular inspections of filters, fans, coils, and the water circuit can gradually reduce system efficiency. A planned preventive maintenance program is recommended. To minimize blockages caused by impurities in the water circuit and facilitate maintenance, the use of an optional bypass kit with an integrated dirt strainer is recommended. 

Proper installation, routine maintenance, and periodic inspection of all system components will prevent most operational issues and help ensure that FCU Series Fan Coil Units deliver maximum efficiency, reliability, and long-term performance.

FCU Series Fan Coil Units help regulate indoor humidity levels by removing excess moisture from the air during the cooling process. As ambient air passes over the chilled cooling coil, its temperature decreases, causing the excess water vapor it contains to condense into liquid. 

The resulting condensate water is then collected and discharged through the unit’s drainage system. As a result, the air is not only cooled but also conditioned to a more balanced humidity level. 

This dehumidification process contributes to a more stable and controlled indoor environment, which is particularly important in areas housing sensitive equipment, technical installations, or industrial processes where consistent environmental conditions are essential.

Yes. FCU Series Fan Coil Units are equipped with standard filtration systems, and additional filtration solutions can be integrated to meet specific application requirements. 

These optional filtration configurations help reduce airborne particulate matter, contributing to improved indoor air quality and a cleaner operating environment. Depending on the project requirements, suitable filter options can be selected to support the desired level of air cleanliness. 

Such solutions are particularly beneficial in sensitive manufacturing areas, technical facilities, and applications where enhanced air quality is essential for maintaining process reliability and environmental control.
