- Ideal for: Corridors, perimeter office zones, narrow retail spaces, and reception areas
6. FCT2 Series – Two-Way Ceiling Cassette Fan Coil Unit
The FCT2 Series delivers conditioned air in two opposing directions, suited to elongated spaces, narrow rooms, and open-plan layouts where airflow needs to reach both sides of a central ceiling position.
- Dual-direction discharge – Even air distribution across elongated or rectangular spaces
- Flexible blade configuration – Adjustable louvers for customised airflow direction to suit room geometry
- Ideal for: Meeting rooms, elongated offices, restaurant dining areas, and retail stores
7. FRC Series – Round Ceiling Cassette Fan Coil Unit
The FRC Series is a circular ceiling cassette, combining 360° airflow performance with a distinctive round panel design that complements contemporary and high-end architectural interiors where the standard square cassette panel is aesthetically undesirable.
- Round panel design – Circular ceiling panel suits modern, minimalist, and architecturally sensitive interiors
- 360° airflow distribution – Delivers even temperature across the zone from a central ceiling position
- Premium aesthetic – Ideal for spaces where the FCU is a visible architectural element
- Ideal for: Luxury hotel lobbies, high-end retail boutiques, premium offices, and restaurants with design-led interiors
8. FWM Series – Wall-Mounted Fan Coil Unit
The FWM Series is a surface-mounted wall fan coil unit, the most straightforward FCU installation type, requiring no ceiling void and no ductwork. It is ideal for spaces where concealed installation is not possible or where a simple, cost-effective zone cooling solution is required.
- No ceiling void required – Surface wall mounting suitable for any room type regardless of ceiling construction
- Simple installation – Minimal on-site work, chilled water connections, condensate drain, and electrical supply only
- Auto-swing louvers – Horizontal and vertical airflow direction control for optimised air distribution
- Ideal for: Clinics, server rooms, classrooms, retail shops, guesthouses, and retrofit installations
Standard vs District Cooling Models
The FCU range is available in both standard chilled water and district cooling configurations:
Standard Chilled Water Models
- Connected to a building’s own chilled water plant (chiller + cooling tower or air-cooled chiller)
- 2-pipe or 4-pipe configurations for cooling-only or simultaneous heating and cooling
- Standard chilled water flow and return temperatures (typically 6°C/12°C or 7°C/14°C)
District Cooling Models
- Purpose-designed for connection to district cooling networks, widely used across Dubai, Abu Dhabi, and GCC master-planned developments
- Rated for higher chilled water supply temperatures and pressures typical of district cooling networks
- Comply with district cooling provider specifications including DEWA, Empower, Tabreed, and other UAE district cooling utilities
- Suitable for large mixed-use developments, master-planned communities, and high-rise towers served by centralised district cooling plants
Energy Efficiency & Quiet Operation
Every FCU in the range is engineered for low energy consumption and quiet operation:
- EC (Electronically Commutated) fan motors – Available across the range for up to 50% reduction in fan energy consumption compared to standard AC motors
- High-efficiency chilled water coils – Optimised fin and tube geometry maximises heat transfer per unit of chilled water flow, reducing pump energy requirements
- Multi-speed fan control – Low, medium, and high speed settings allow occupants to balance comfort and noise according to preference
- Low noise fan assembly – Forward-curved or backward-curved fan wheels selected for optimal noise-to-performance ratio at each capacity
- Minimum sound levels – Indoor units achieve noise levels as low as 28 dB(A) on low speed, suitable for bedrooms, executive offices, and noise-sensitive healthcare environments
- Standby mode – Units reduce fan speed during unoccupied periods while maintaining minimum chilled water flow to prevent coil condensation issues
BMS & Smart Controls Integration
All FCU series support comprehensive control and building automation integration:
- Fan coil unit controllers – 2-pipe and 4-pipe PI/PID controllers with LCD display for precise zone temperature management
- Modbus RTU / BACnet MSTP – Standard communication protocols for integration with any BMS platform
- Centralised BMS control – All FCUs across a building manageable from a single BMS interface for centralised scheduling, monitoring, and energy management
- Occupancy sensors : Compatible with PIR occupancy sensors for automatic standby or setback when zones are unoccupied
- Smart thermostats : Compatible with wired and wireless smart thermostats for enhanced occupant control
- Group scheduling : Zone grouping by floor, department, or building area for efficient centralised control

Why Chilled Water Fan Coil Units Are the Preferred Choice
In large commercial and residential buildings served by central chilled water plants or district cooling networks, fan coil units are the dominant terminal device for a range of practical and economic reasons:
- No refrigerant in occupied spaces – Chilled water FCUs use water as the heat transfer medium eliminating refrigerant leak risk in occupied zones
- Long service life – Simple, robust construction with few moving parts delivers 15–25 year service life with minimal maintenance
- Low operating cost – Fan coil units are among the most energy-efficient terminal devices available particularly when paired with EC fan motors
- Individual zone control – Each FCU operates independently, delivering precise zone-by-zone temperature management across the building
- Compatibility with district cooling – The UAE’s extensive district cooling infrastructure makes chilled water FCUs the natural terminal device choice for the majority of commercial and residential developments in Dubai and Abu Dhabi
- Easy replacement – Standardised connections and compact design make FCU replacement straightforward without major building works
