FH4-M trench heaters are designed for high-capacity heating in spaces with strict acoustic requirements. Due to the extremely low noise level, the units are widely used in bedrooms, hotel rooms and living spaces where thermal comfort must be ensured without audible background noise.
The units are suitable for low-temperature heating systems, including heat pumps and condensing boilers. Integrated EC fans ensure high convection efficiency, even heat distribution and fast response to temperature changes.
FH4-M units are equipped with durable stainless steel casings adapted for pedestrian loads and daily use in residential and commercial applications. For architectural integration, double-sided aluminum or oak wood grilles are available.
