Description
• WallAir is a wall-mounted induction unit for supply air, cooling or optionally, cooling and heating.
• The unit is installed above a suspended ceiling in adjacent space or room, with a joint wall-mounted supply and return air grille.
• WallAir is primarily designed for offices, health facilities and other premises where this installation method is suitable.
• Supply air and return air are distributed in the room horizontally along the suspended ceiling.
• With the supply air flow as the driving pressure, room air is induced through the finned coil, which removes or, where applicable, adds heat.
• The front front of the unit is divided into two sections, the upper part being a supply air duct fitted with nozzles which creates the induction in the appliance. The lower part of the front consists of a return air grille.
• The supply air part of the grille has adjustable slats for a draught-free indoor climate, while the return air section has fixed horizontal slats.
• The grille is detachable for inspection and maintenance purposes.
Material options and finishes
• Powder coated finish.
Sizes (mm)
• Supplied in 4 different lengths:
600/800/1000/1200
• Duct dimension Ø125 placed on the back of the unit.
Configuration alternatives
• Version for cooling or cooling and heating.
• Water connection side:
– left / right.
Options and accessories
• Integrated control for stand-alone operation or connectivity to parent BMS.
• Complete selection of connection accessories:
– Adjustment damper type ZMC
– Setpoint changer.
– Connection hoses.
– Control valves for water supply.
– Valve actuators.
• Device housing and duct connection made of hot-dip galvanized sheet steel with EPDM rubber gasket.
• Visible parts: casing, frame and perforated front grille made of sheet steel, powder coated in white RAL standard colour. Other colours are available.
• Coil made of copper tubes with aluminum slats.
• Plastic details of Polyethylene.
• 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 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.
• In order to be able to adjust the drive 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.
• The supply air flow, q (l/s or m3/h) is checked by measuring the driving pressure P (Pa) in the hose from the supply air duct. When the prescribed operating pressure has been measured, the required 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.
• 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.
