FB-A Ultra and Ultra plus

FA-A Ultra with recirculating air suction grid

Consistent Heat or Comfortable Coolness Type „Ultra“ is fulfilling technically and optically high demands. It is impressive even in exclusive ambience.

Ultra is blowing out horizontally on six sides with 15° inclination, reaching an especially consistent distribution of the tempered air in the room.

Ceiling air units FB-A Ultra are rated for pure heating operation or for combined heating / cooling operation (FB-A-K).

Units with cooling function are equipped with a condensate tub below the cooling register and a condensate pump.

Air capacity up to 3750 m³/h

Heating capacita up to 40 kW

Cooling capacity up to 19,9 kW

Enormously powerful Type „Ultra plus“ of series FB-A is extending series Ultra by a diagonal fan unit for hightest air capacities.

Due to diagonal air flow and favourable sound behaviour, the FB-A Ultra plus ceiling units can used wherever the capa-city of FB-A Ultra units with their low pressure axial fans isn‘t sufficient any more.

Ultra plus will make it even for larger rooms without efforts - and especially quiet.

Moreover, the special scoop shape of the fan wheel is extremely energy-saving.

Recirculating, Mixed, Outside Air Operation

Out versatile product range - tailor-made for your requirements.

In recirculating air operation, the air is sucked out of the room to be heated and blown back into the same room after being heated.

This procedure causes lowest operating costs.

In mixed air operation, fresh air (fresh air amount variably adjustable) is sucked toge-ther with room air.

This procedure reduces heating costs, using partially already heated air out of the hea-ted room, and on the other hand provides the necessary fresh air.

In outside air operation, the air is sucked directly from outside for heating or cooling.

In suitable circumstances, this procedure guarantees clean and unspoilt air.
