     FCH are among the most powerful trench heaters designed for heating and cooling.

  • Both heated and cooled air is raised right up the ceiling to result in an even distribution throughout the room.
  • 4 and 2 pipe connection versions are available. The 4 pipe connection guarantees maximum flexibility, whereas the 2 pipe connection will ensure the maximum capacity.
  • The air flow passing through the appliance is continuously filtered to trap a considerable part of the dust and dirt in the room and protect the convector from contamination.
  • The set includes drain pans that allow the device to operate both above and below the dew point. 
  • Quiet and extremely economical EC fans increase the convection efficiency more than 4 times, almost without any sound.
  • Due to extremely low inertia, can quickly increase and precisely maintain the set room temperature, providing the room with exactly as much heat as you require just when it is required.
  • Create an effective warm air curtain for large windows, without allowing cold to penetrate the premises. The heat is perfectly distributed throughout the room.
  • Operates very well with low-temperature heat sources, such as heat pumps or condensing boilers.
  • Fully floor-mounted, and therefore do not impede free passage.
  • Perfect for any interior, as the only visible element is the grill, the material and colour of which can match the floor covering.
  • May be walked on and can easily withstand the weight of a number of adults.
  • Supplied with a stainless steel casings and copper-aluminium heat exchangers, to ensure they remain extremely reliable over the long-term.
