EUROVENT certified Air Handling Units:
• 32 models with air volumes: from 2.000 to 110.000 m3/h • Special execution for higher air volumes
This leaflet contains a summary of the CTL series air handling units, illustrating their main characteristics. The purpose is to describe the standard range, while at the same time highlighting the flexibility and best technical solutions possible for meeting different needs at site. Constructional quality and the components used guarantee reliability, functionality and efficiency that last over time. The CTL units are available in 32 sizes, covering a vast range of air flows, and are designed using a simple and flexible modular system.

SIZES Air handling units are sized by selecting the components that meet the system’s thermo-mechanical design requirements. The unit is selected according to air flow and air velocity through the coils. The following values are recommended:
- Ventilation section (no filters, no heat exchangers): max 4,0 m/sec - Heating coil: max 3,5 m/sec - Cooling coil: max 2,8 m/sec
The CTL range is available in 32 sizes for nominal air flow from 1,000 to 100,000 m3/h. The tables show the possible choices based on these two main parameters. For greater clarity, the table below illustrates: CTL: CTL model H: Unit height, excluding the base (add 95/150 mm) L: Section width Sb: Coil face surface area V: Air flow m3/h

Internal insulation The following types of thermal and acoustic insulation can be used: • Polyurethane foam, density 40+/-5 kg/m3, thermal conductivity 0.022 (W/mk). Reaction to fire in accordance with ISO 3582 DIN 4102:B3. • Mineral wool, as well as being a natural material with good thermal insulation properties, has an open cell structure that makes it an excellent soundproofing material; indeed it combines five fundamental features, including thermal-acoustic insulation and excellent reaction to fire. Density 90/100 kg/m3, thermal conductivity 0.045 (W/mk). Sound attenuation 23 mm polyurethane foam panel.
Rain cover Required for installations outside of the equipment room, made from: • coated sheet metal, 6/10 mm thick • galvanized sheet metal, 6/10 mm thick • Peraluman sheet metal, 8/10 mm thick Secured directly onto the sections using suitably insulated and sealed screws.
10
Dampers In the standard version, these have an aluminium frame, aluminium louvers with airfoil blades, 100 mm pitch. The specially-shaped blades ensure tightness when closed. Upon request, these can be fitted with seal gaskets on the sides and on the louvers. All dampers came with 12 mm diameter motor drive shaft for manual or electrical servo control. Can be installed both outside and inside the unit.
Filters The air filter section is a fundamental part of the air handling unit, as it removes any contaminants from the air flow. Before choosing a filter, several points need to be assessed, including: • Type of application • Efficiency • Dust accumulation • Pressure drop The following table helps select the best filter.

MIDDLE EFFICIENCY FILTERS Middle efficiency or coarse filters are used as the first or second filter stage.
