FC series natural trench heaters are designed for space heating without fans, operating on the principle of natural air circulation.
The units operate completely silently, making them particularly suitable for spaces with high acoustic comfort requirements, such as bedrooms, hotel rooms, and residential areas.
Thanks to their reliable design with no moving parts, FC convectors offer an exceptionally long service life and require no complex maintenance.
Low thermal inertia allows rapid response to temperature changes, making FC one of the most energy-efficient solutions, capable of precisely maintaining the set room temperature (up to ±0.5 °C).
The convectors are equipped with robust stainless steel casings, ensuring durability and reliable operation even in areas with intensive use.
The FC construction is designed for pedestrian loads – the convector can be safely walked on and is capable of withstanding the weight of several adults.
For architectural integration, reversible aesthetic grilles made of aluminium or solid oak are used, allowing the solution to be matched to the floor finish and overall interior design concept.
