Trench Fan Coils FCH
High heating and cooling capacity, allowing use as primary heating units even in low energy-efficiency buildings
Extremely low noise level, suitable for spaces with strict acoustic requirements
Integrated condensate collection trays, enabling operation below the dew point
2- and 4-pipe models:
– 4-pipe system – maximum heating and cooling flexibility
– 2-pipe system – maximum output capacity
Efficient operation with low-temperature heat sources, such as heat pumps and condensing boilers
Low thermal inertia – heating (or cooling) is supplied strictly according to actual demand, significantly reducing energy consumption and preventing overheating
EC fans – quiet operation and maximum energy efficiency, providing up to 4x higher convection performance
Robust stainless steel casings, designed for pedestrian loads and capable of withstanding the weight of several adults
Reversible aesthetic grilles made of aluminium or solid oak
Designed and manufactured in EU
FCH series high-capacity trench fan coil units are designed for efficient space heating and cooling, ensuring comfort even in low energy-efficiency buildings. Thanks to their high heating and cooling capacity, these units can be used as primary heating and cooling devices.
The units feature an extremely low noise level, making them suitable for spaces with strict acoustic requirements, such as residential areas, hotel rooms, and offices. Integrated condensate collection trays allow reliable operation below the dew point, ensuring stable and safe cooling performance.
The FCH series is available with 2- or 4-pipe connections. The 4-pipe system provides maximum flexibility for independent heating and cooling control, while the 2-pipe system is designed for maximum instantaneous output.
The units operate efficiently with low-temperature heat sources, such as heat pumps and condensing boilers, making them easy to integrate into modern, energy-efficient HVAC systems. Low thermal inertia ensures that heating or cooling is supplied only according to actual demand, significantly reducing energy consumption and preventing overheating.
EC fans ensure quiet operation and maximum energy efficiency, achieving up to four times higher convection efficiency compared to natural convection solutions. This allows rapid and even distribution of heating or cooling throughout the entire room volume.
FCH units are equipped with robust stainless steel casings, designed for pedestrian loads and capable of supporting the weight of several adults. Reversible aesthetic grilles made of aluminium or solid oak allow easy integration with floor finishes and interior design concepts, while maintaining a minimal visual impact on the space.
