Modular air handling unit
General description23LX Lennox modular air handling units satisfy all forms of air treatment such as ventilation, filtration, heating, cooling, humidity and recovery.The 23LX Lennox air handling units are available in 44 sizes to cover an airflow range from 1 000 up to 100 000 m3/h with total pressures up to 2 500 Pa.Special units can also be supplied for airflows and pressures outside the normal range. The wide range of unit sizes allows the best choice in relation to the requested face velocity.The 23LX units have been developed and dimensioned in length, width and height, using a module of 160 mm with 28 basic sizes and 16 low profile sizes. When site conditions request it, the low profile units have a distinctly rectangular cross-section in order to reduce the height while increasing the width.

ConstructionFrame and panels:
Frame and panel structure of 23LX air handling units have been developed with particular care on thermal insulation and resistance.Casing consists of aluminium frame with 50 mm sandwich panels, in a wide range of thickness and materials, are insulated with injected polyurethane to 45 kg/m3 density or mineral wool to 90 kg/m3 density.Internal surface of the unit is completely smooth and no screws are visible inside the unit.Gasket between the panels to ensure airtight seal, to eliminate thermal bridges, to reduce air leakages and to eliminate dust accumulation.3 way corner joint is in glass fibre reinforced nylon
EN 1886 Classification for standard construction: Mechanical resistance: D1 Leakage : L1/L2 Filter by-pass: F9 Transmittance: T2 Thermal bridges: TB3 (standard), TB2 on option
Base frame: Base frame consists of galvanized steel “C” shaped frame 2,5 mm thickness according to the unit length and it is supplied with four corner feet with lifting holes suitable for 2” diameter thickness walled steel pipe.

Options and available configurationsCoils:
Water, direct expansion, steam and electric coils, housed in a separate section on slide rails. On request ARI certified coils.Coils are factory tested at 30 Bar by injecting with dry air while the coil is immersed in water.Electric coils are supplied with safety thermostat with manual reset.
Recovery sections, heat recovery module available in R/A coils, cross flow, heat wheel and heat pipes, heat wheels and run around coils.
Drain pans: Condensate drain pans in aluminium or stainless steel and can be inclined to ensure complete drainage (option).
Fan sections:
Fan sections include fan, electric motor, motor slide rail, belt driven transmission, base frame with anti-vibrating mounts, flexible connection on the fan outlet, earthing cable on the fan and motor base frame.
When plug fans are supplied the drive motor is mounted directly on the fan shaft. Inverter can be supplied to control motor speeds.
Fans are double inlet double width, DIN R20 series, available in:Forward curved for low pressuresBackward curved for medium-high pressuresBackward curved airfoil blades for high efficiency and medium-high pressures.
Motors are three phase asynchronous, closet construction with external fan, squirrel cage, horizontal shaft type B3, IP55 protection with F class insulation, IEC, CEI and UNEL approved. On request inverter motors, monophase, antispark, with bimetallic protection, with heater …
Transmissions are V belts and pulleys type SPZ, SPA, SPB and SPC (fixed or variable pitch)
Fans up to size 400 are mounted on rubber antivibration mounts and all other sizes are fitted with spring mounts.
Attenuators, standard or envelopped
Safety devices: Motors are fitted on belt tensioning skid provided with manual adjustment. Transmission is achieved by V-belt and pulleys
