Consistently straight
A61/A71 High performance module

A61/A71 high capacity fins constitute a highly efficient radiant ceiling system that ensures the even distribution of heating and cooling energy in a room, creating a pleasant indoor climate. The special geometry of the fins with rounded aluminum profiles ensure freedom from draughts and compliance with standards regarding room air velocity, even at the highest cooling capacity. The fin elements can be arranged as an island or a field on the ceiling.

  • Very high heating and cooling capacity
  • With optional absorbers: Advanced sound absorption values (class B)
  • Powerful and energy efficient
