Ultimate thermal comfort through innovative design


The Grand fan coil unit is designed to provide draught-free air conditioning with ultimate thermal comfort to indoor air through its ingeniously designed two-way grille. The fresh air is supplied to the room from the top of the grille, while the return air intake takes place from the bottom of the grille. The supply air is directed along the ceiling, which guarantees the draught-free cooling of the room.

Combined with versatile and adaptive Vari Pro automation and the award-winning Vari PRO room controller, the Grand makes an excellent choice for air conditioning when high thermal comfort is sought.
The Vari Pro automation guarantees the system’s precise control of air temperature and flow, and ensures that the conditions in indoor spaces remain consistently pleasant while the energy consumption of the air conditioning is kept to a minimum.

| Energy efficient and silent

  • Maximised heat transfer area of the coil guarantees maximum cooling capacity with minimised energy consumption
  • Improved cooling capacity allows the fan to be operated at a lower speed, which reduces the sound level
  • Innovative grille design optimised in accordance with the EC fan ensures minimal energy consumption
  • Silent operation guaranteed by unit design and soundproofing
