Ultra high performance Environmentally friendly with heat recovery solutions Optimised performance thanks to the control system Air flowrate: 1500 to 6000 m 3 /hr and a compact 400 mm profile Available pressure: 100 to 1000 Pa with high output and minimum sound level USE The Air Compact air-handling unit is especially suitable for decentralised air-conditioning applications. It can be CEILING MOUNTED or incorporated into a FALSE CEILING with access from below, in RAISED FLOORING or directly in the FLOOR itself with access from above. It can also be installed vertically against a WALL: Upward discharge only with cooling coil (max 4 rows) Upward or downward discharge for the other configurations. RANGE The Air Compact range consists of 3 sizes ranging from 1500 m 3 /hr to 6000 m 3 /hr. Units are only 400 mm thick and the width varies depending on the size: DESCRIPTION Casing Extra-flat high quality AHU, two-tone (Ral 9006 and 7024) 25 mm galvanised steel exterior casing with double wall construction and glass-wool insulation, internal 275 g/m² galvanised sheet, resistance to salt mist: 250 hours Easy access via hinged door (1 or 2 unhingeable doors) Classification in accordance with EN 1886 Airtightness : L2 Mechanical resistance : D2 Other characteristics : T3, TB2 and F9 Hydraulic connection On the left: L or on the right: R (specify on order) The are available in the following models: ceiling mount HC, floor mount HF, or Vertical wall V, easily secured using angle brackets equipped with antivibration mounts Angle brackets of the same type can be used to interconnect the air-handling and additional from the outside. Air Compact 25: 750 mm Air Compact 40: 1310 mm Air Compact 60: 1880 mm Angle bracket covers give the product a perfect final appearance. 4 standard unit lengths mean that various configurations are possible The lengths are 610, 830, 1100, ; models will be determined by the selection software. RA damper Intake-side or discharge-side dampers, whether for air intake, frost protection or insulation purposes, are easily secured to the air-handling unit or additional unit. The guide markings for dampers are identical on both the unit and the duct. The dampers are class 1 or class 3 in accordance with standard EN 1751. Their thickness in the direction of airflow is 110 mm Height is 310 mm. They are fitted with both motorisable and manual control (spindle length: 80 mm). 1
2-way mixing box: CM2 Box enabling fresh air and return air to be mixed by a moving vane ensuring flow metering and distribution. Manual and motorisable control. 3-way mixing box: CM3 Box enabling removal of extracted air, introduction of fresh air and air recycling via the intermediary of two moving vanes ensuring flow metering and distribution. Manual and motorisation control possible. HI HS SI Straight or Curved Plenums: PLD PRS Can be mounted on either intake or discharge. 2 plenum types: - intake or direct discharge: frame with double deflection grille, length 25 mm. - intake or discharge at RIGHT ANGLE: fitted with a double deflection grille, length 330 mm. PLD PRS Filtration In addition to a full section G4 filter base assembly, the following solutions are available: G4, F5 pleated, F6-F7- F8-F9 rigid pockets in universal sizes, with a compression system starting at filtration efficiency class F6. - Pressure taps mounted as standard on each stage. - Optional liquid filled pressure gauge. Hydraulic or evaporator coil in the AHU or vertical unit. CFV The coils are totally DRAINABLE. Piping is fitted with threaded ends with purge and drain plugs (Ø 1/8 ). - In heating mode: Size 25: 1, 2, and 3-row coils are available, Size 40 and 60: 1, 2, and 4-row coils are available, A frost protection thermostat with automatic reset can be installed on the coil. - In refrigeration mode: For each size there are 3, 4, and 6-row chilled water coils and 3, 6 rows of direct expansion coils. The section is fitted with an eliminator, maximum face velocity: 3.1 m/s and a stainless steel condensate container. Container isolation option using closed-cell foam. For vertical applications, max 4 rows in the CFV unit. 2
Electric heater The electric heater can be installed in the AHU (Power module 1) or in an additional BEC unit (Power module 1 or module 2). It is fitted with 2 safety devices: 1 thermostat with automatic reset and 1 Klixon with manual reset. Depending on the nature of elements adjacent to the electric heater, (filter or motor, for example), a radiation shield may be installed upstream or downstream. Sound attenuator Fitted with a horizontal sound attenuator, height 200 mm, length 600 mm. Plate recuperator Three-phase 400-Volt configurations are available Plate recuperator, aligned arrangement 25, 40, 60 size or offset arrangement 25 and 40 size: available in 2008. Fresh Air Extracted Air Return air Fresh Air Return air Discharged Air ALIGNED ALIGNED OFFSET (view from above) VENTILATION Single size fan (wheel size: 280mm) for the entire range.

4 motor capacities are defined and cover the entire operating range: 0.25 kw 4-pole; 0.55 kw 4-pole; 0.75 kw 2-pole; 1.50 kw 2-pole The frequency inverter is needed to reach the desired operating point. If there are 2 fan motor, 1 single frequency inverter controls both motors. The frequency inverters are connected to a SINGLE PHASE 230 V power supply and supply the motors with three-phase current.
