Main features

• Supply air and return air are distributed to the room via a horizontal supply air grille  along the suspended ceiling
• High cooling/heating effect with low noise levels
• Prepared for connection of control and electricity
• Supply air grille with adjustable slats for a draught-free indoor climate
• Supply air flow from 8 l/s (29 m3/h) at 50 Pa up to 50 l/s  (540 m3/h) at 150 Pa

Description

• HotelAir-HF (Hi-Flow) is a ceiling-mounted induction unit for supply air, cooling or optionally cooling and heating.

• The unit is installed in a suspended ceiling with a horizontally facing wall grill for supply air and vertically facing return air intake in the suspended ceiling.

• HotelAir-HF is primarily designed for hotel rooms and other premises where this installation method is suitable.

• The supply air flow is injected into the
plenum box of the beam and distributed
through the supply air nozzles. 

• With the supply air flow as a driving force, room air is induced through the finned coil, which then removes or, where applicable, adds heat.

• The mix of supply air with conditioned return air is discharged via the supply air grille horizontally along the ceiling.

• The supply air grille has horizontal slats while the return air grille is made of perforated sheet metal and can be easily opened for inspection and maintenance.

• Product versions featuring heating are delivered in four different capacities depending on the dimensioned heating requirements for each specific project:
– Effect variant 1: capacities up to approx. 950 W.
– Effect variant 2: capacities up to approx. 1100 W.
– Effect variant 3: capacities up to approx. 1300 W.
– Effect variant 4: capacities up to approx. 1450 W.

• For more information about standard materials and colors, see the separate document Product specification which can be downloaded from our website.


• The following information is only a general overview of the of assembly, installation and adjustment procedure. Always refer to the product's operation and maintenence documention (DU-SE/DV-DK) for detailed installation instructions.

• The product is connected to a circular supply air duct. Connection to a straight mounted flexible duct is not recommended.

• Heating and cooling water pipes are installed by a plumbing contractor.

• The length and width of the unit are adapted to fit standard support structures.

• The product can be suspended using a threaded rod or mounted directly against the ceiling.

• The unit is supplied with 4 factory-fitted suspension brackets for pendants (one in each corner). Fittings with pendants can be adjusted separately in four directions.

• Ensure that no damage occurs to the cooling/heating coil when tightening valves and connections. To avoid this, always use a suitable wrench as counterweight.

• When installing the beam, space should be reserved for opening the front grille and accessing the device for cleaning, inspection and service. The return air grill is easily opened for inspection and service.

• The product has fixed nozzles and is delivered for specific air flow at a certain nozzle pressure according to customer requiement (specified at order placement).

• It is possible to have a certain number of nozzles plugged on delivery in order to increase airflow later if necessary.

• The supply air flow is checked by measuring the operating pressure in any nozzle across the nozzle strips. When the prescribed operating pressure has been measured, the specified air flow has been achieved.

• For calculation of K factors, see tables and calculation formula in the operation and maintenance document (DU/DV) of the beam.

• In order to be able to adjust the operating pressure, the product should be preceded by an comissioning damper mounted in the duct before the  unit, e.g. ZMC or SPD, but not an iris-type damper.

• When installing the commissioning damper, requirements for the preceding straight section should be taken into account, see the specific damper's documentation for detailed information.

• When the unit is supplied with control options, the product is delivered internally pre-wired from the factory. See separate documentation depending on the current option regarding wiring, commissioning and operation of control and powering components.
