1. Energy Efficiency and Cost Savings

Energy efficiency is often the main consideration in modern HVAC system specifications and FCUs offer a cost-effective solution by optimising energy use. With advanced EC (electronically commutated) fans and variable speed controls, FCUs can adjust airflow to match demand, reducing power consumption and keeping energy costs low. Compared to alternative systems like variable refrigerant flow (VRF), FCUs allow for efficient heating and cooling without high refrigerant usage making them a sustainable option.

Additionally, FCUs can integrate seamlessly with heat pump systems, further improving energy efficiency. By using low-grade chilled and hot water, they operate effectively in conjunction with renewable energy sources such as air-source and ground-source heat pumps.

2. Superior Climate Control with Customisable Options

Biddle’s fan coil units, including the ProAir and DecoQT ranges, are designed with advanced control options to provide precise climate control. These units offer multiple control methods:

Basic control: Simple speed controllers allow for easy airflow adjustments.

Project-specific controls: Units can be integrated with third-party systems for seamless automation.

Direct digital control (DDC): Enables advanced features like remote monitoring, fault detection and integration with building management systems (BMS).

These options provide flexibility for consultants and installers, ensuring that FCUs meet the unique demands of different environments, from office buildings to high-end residential developments.

3. Flexibility in Installation and Application

FCUs are highly adaptable and can be installed in various configurations, including ceiling-mounted, wall-mounted or underfloor setups. They can be used in both new construction and retrofit projects, offering solutions for spaces with limited ceiling voids.

Biddle’s ProAir Series, for example, is available in two depths (270mm and 235mm) to accommodate different spatial constraints. Additionally, units can be customised with left- or right-hand orientation, acoustic enhancement, and painted finishes (to RAL), making them suitable for diverse applications such as hotels, offices, retail spaces, and schools.

4. Low Maintenance and Long-Term Reliability

Designed for durability and ease of maintenance, FCUs feature accessible filters, removable panels, and straightforward servicing. The inclusion of G2 or G3 filters ensures better air quality while protecting the coil and fans from dust and debris buildup.

Biddle’s DecoQT model, for instance, includes tool-free access for filter changes, allowing for easy vacuum cleaning by maintenance teams. Additionally, condensate trays are designed with insulation to prevent moisture formation and corrosion, ensuring long-term reliability.

5. Quiet Operation for Enhanced Comfort

Noise levels are a critical factor when specifying HVAC solutions, particularly in office buildings, hotels and educational institutions. FCUs are designed to operate at low noise levels while maintaining efficient air distribution.

The DecoQT fan coil, for example, operates as low as 28dB(A), ensuring a quiet indoor environment. The acoustic design of Biddle’s units minimises sound emissions even when running at full capacity, making them ideal for noise-sensitive applications such as hotel rooms where guest comfort is cruical.

Conclusion

Fan coil units continue to be a preferred HVAC solution due to their energy efficiency, advanced control options, installation flexibility, low maintenance and quiet operation. With Biddle’s range of high-performance FCUs, specifiers can confidently integrate these systems into projects, ensuring optimal indoor climate control while maximizing energy savings.
