DESCRIPTION

■ Casing

Double-wall casing with 25 mm glass wool insulation. Externalpanelwork made from painted galvanised steel (RAL 9006 and7024). Galvanised sheet metal interior.Hinged doors for easy access (1 or 2 lift-off doors)

■ Hydraulic connectionOn the left: L or on the right: R (specify on order)The units are available in the following models: ceiling mountHC , floor mount HF , or Vertical wall V , easily secured usingangle brackets equipped with antivibration mounts

Angle brackets of the same type can be used to interconnectthe air-handling units and additional units from the outside.

Angle bracket covers give the product a perfect finalappearance.4 standard unit lengths mean that various configurations arepossible The lengths are 610, 830, 1100, 1400 mm; models willbe 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 tothe air-handling unit or additional unit.The guide markings for dampers are identical on both the unitand the duct.The dampers are class 1 or class 3 in accordance withstandard EN 1751.Their thickness in the direction of airflow is 110 mmHeight is 310 mm.They are fitted with both motorisable and manual control(spindle length: 80 mm).

The solution for installation in confined spaces .The CTA ultra slim range offers all the essential

functions for quality air handling .

USE

The Air Compact air-handling unit is especially suitable for decentralised air-conditioning applications.

It can be CEILING MOUNTED or incorporated into a FALSECEILING 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 from1500 m 3 /hr to 6000 m 3/hr.Thickness 400 mm, 4 standardised box lengths determined bythe selection software depending on the differentconfigurations.

Air Compact 25: 750 mm Air Compact 40: 1310 mm Air Compact 60: 1880 mm

Air flow rates: from 1500 to 6000 m 3 /h in 3 sizes.

Available pressure: from 100 to 1000 Pa(high performance and reduced sound level)

■ Hydraulic or evaporator coil in the AHU orvertical unit. CFV

The coils are totally DRAINABLE. Piping is fitted with threadedends 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 canbe installed on the coil.

- In refrigeration mode:For each size there are 3, 4, and 6-row chilled water coils and3, 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.

■ 3-way mixing box: CM3

Box enabling removal of extracted air, introduction of fresh air andair recycling via the intermediary of two moving vanes ensuringflow metering and distribution.

Manual and motorisation control possible.

■ Straight or Curved Plenums: PLD PRS

Can be mounted on either intake or discharge.

2 plenum types:- intake or direct discharge: frame with double deflectiongrille, length 25 mm.- intake or discharge at RIGHT ANGLE: fitted with a doubledeflection grille, length 330 mm.

■ 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 compressionsystem starting at filtration efficiency class F6.

- Pressure taps mounted as standard on each stage.- Optional liquid filled pressure gauge.

■ Electric heater

The electric heater can be installed in the AHU (Power module1) or in an additional BEC unit (Power module 1 or module 2).

It is fitted with 2 safety devices: 1 thermostat with automaticreset and 1 Klixon with manual reset.

Depending on the nature of elements adjacent to the electricheater, (filter or motor, for example), a radiation shield may beinstalled upstream or downstream.

Air Compact 25: fitted with 1 fan Air Compact 40: fitted with a choice of 1 or 2 fans depending on flowrate

Air Compact 60: fitted with 2 fans

Fan without scroll (FREEWHEEL), with motor at shaft end,pressure range 100Pa min to 1000Pa max.

Three-phase 400-Volt configurations are available

VENTILATION

Plug fan, direct drive. Selected for its excellent performance and sound level, as shown below:

■ Designations and lengths of additional units

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 operatingpoint.If there are 2 fan motor units, 1 single frequency inverter controlsboth motors.The frequency inverters are connected to a SINGLE PHASE230 V power supply and supply the motors with three-phase current.Optional frequency inverters with THREE PHASE 400 V supply
