Modular air handling units.


• The ADV Next Air range is developed from the new Rhoss air handling vision.

Innovative ideas and cutting-edge technology are the winning combination that characterise it.
This, together with our thirty years of experience in the sector, leads to the new innovative line of air handling units that looks to the future of air conditioning. The strength of the product lies in the use of latest generation creative engineering solutions, preserving the qualitative excellence and the reliability traits that have made Rhoss a well-known name. The fully modular nature and the wide range of configurations come together in the Next Air range to create perfect balance between customisation and standardisation, flexibility and industrialisation.

• Sturdy and self-bearing structure made from one 50 mm thick single-piece sandwich panel, internally and externally hot galvanised sheet steel painted with oil-free polyester paint, highly resistant to corrosion. The internal surfaces are completely smooth to inhibit microbial proliferation and prevent the accumulation of dust.
• Insulation of self-extinguishing polyurethane base resins with a density of 48 kg/m3. Fire reaction Euroclass Cs3d0.
• The step-type full-face front inspection sandwich panels are housed in the profile seat, with thermal cut interruption, a soft PVC double gasket that simultaneously ensures tightness and prevents humidity, water or any other unwanted element from entering the machine.
• The fixing profiles are made of latest generation plastic material (PVC-RAU). Specifically made on Rhoss design, their geometry ensures perfect thermal insulation of the structure and complete interruption of thermal bridge, optimally resistance to exposure to sunlight (UV rays) and atmospheric agents, ensuring outstanding resistance to ageing.
• The condensate drain pans are made of magnesium and aluminium alloy sheet steel, ensuring excellent resistance to corrosion. They are installed inside the machine structure and are fully insulated.
Thanks to the double inclination, full drainage of fluid is guaranteed thus avoiding any kind of unwanted stagnation.
• All units are suitable for both indoor and outdoor installation.
