Fan Coil Unit Aquaris SilentDescriptionDescription of the equipmentThe Aquaris Silent fan coil units are air-conditioners that are especially designed for the decentralised use, for heating or cooling with circulating air.The fan coil units guide the air to be treated through the heat exchanger where it can be heated or cooled in a particularly energyefficient way. They are used to bring the air quickly to the desiredtemperature and require only small heating or cooling surfaces.The optimised heat transmission allow lower supply temperatures during heating. And higher supply temperatures duringcooling. This minimises the line losses and saves energy on theway from the boiler or cold water generator to the end device.With different fan speeds or continuous control and valves to influence the flow rate, the device power can be controlled in aflexible way and adapted to nearly all conditions.Starting from the ambition to provide maximum adaptation tothe architectural situation of the room to be air-conditioned, thefan coils are produced in different models - ranging from unitsto be installed in false ceilings and floors (horizontal model) tounits for visible mounting with device casing (vertical and horizontal models).Base unitThe base unit consists of a housing made of galvanised steelwith thermal and acoustic insulation. A motorised fan, one ortwo heat exchangers, a filter and a condensate pan are integrated in the unit.Characteristics- Air throughput from 160 to 1850 m3/h- Cooling capacity: from 1 to 8.3 kWa Heat exchanger- Heating capacity: from 1.25 to 11 kWb Housing- Static pressure: up to 70 Pac Motorised fand Filtere Condensate panAdvantages- Flexible assembly and installation versionsHousing- High cooling and heating capacitiesThe housing of the device consists of profiles and covers madeof galvanised sheet steel having a 6 mm thick insulation.- Control technology adapted to any demand- Low noise generation or reduced sound pressure- Energy-efficient, decentralised air conditioning- Solid compact design- Easy mounting and maintenance- Attractive appearance (unit plus housing)Heat exchangerThe heat exchanger unitcan consist of a single register of 3 rows for coolingand heating operation (forconnection to 2 pipelines)or of two registers of 3 1rows (for connection to 4pipelines).The registers were developed for use with water or a water/glycol mixture and consist ofcopper pipes, aluminium ribs, a manual ventilation and drainagesystem and a frame made of galvanised sheet steel.The length of the register depends on the required performance.The water connections can be attached to the register either onthe left- or right-hand side.Optionally, an electric heating register can be used to supportthe heating mode.11/01 - 3Construction subject to change.Version: 05.04.2013No return possible!

Fan Coil Unit Aquaris SilentCondensate panThe condensate pan can bemounted horizontally or vertically and serves for the collection of the condensatewater below the cooling register. The pan is made of galvanised steel and has athermal insulation (polyethylene with a thickness of 3mm) to avoid the formation of condensation water.The condensation water outlet is located on the same side as thehydraulic connections and can be connected to the on-site drainsystem.Motorised fanThe motorised fan consistsof double-sided intake-operation, dynamically balancedcentrifugal blowers with forward curved blades and direct drive.The fan motors are designedas AC (SP series) or highly efficient EC motors (EC series) andare equipped with maintenance-free friction bearings for a longservice life.For the AC fan motor, 6 steps are made available by a step transformer. The EC fan can be activated with 0-10 V and is infinitelyvariable.The housing and the fan wheel are made of plastic and are optimised for the lowest possible sound pressure.FilterThe air filter of filter class G2and G3 (according to the order) consists of a syntheticfabric on a plastic frame. Thefilters are attached withholding clips and can be dismounted without requiringtools. Moreover, they are distinguished by simple maintenance(washing or compressed air).AccessoriesOptionally, depending on customer request and installationspecific requirements or in order to achieve increased performance and optimum operating characteristics, different additionalcomponents can be integrated, such as plenum boxes for supply and return air, electrical heating registers, flexible connections, connection frames, housings, valve kit, additionalcondensate pan, condensate pump, SCHAKO Ib 1 ventilationgrilles and SCHAKO DBB ceiling diffusers. SCHAKO offers anextensive product range of control equipment.11/01 - 4Construction subject to change.Version: 05.04.2013No return possible!
