Concealed ducted climate systems · Dubai, UAE

ONYX NOVA controls humidity.

Concealed dehumidification, fresh-air treatment and indoor-air-quality solutions for residential, hospitality, commercial and specialised spaces across the UAE.

Installed above the ceiling or in a service space, with its own return and supply ductwork.

Problem recognition

Does your home still feel humid while the AC is running?

Air-conditioning is designed primarily to control temperature. Its ability to remove moisture varies with operating conditions, system design and cooling demand. Lowering the thermostat may make the room colder without providing stable, independent humidity control.

  • Condensation on windows or diffusers

    Water forming on glass, ceilings, ducts or around AC outlets.

  • Recurring mould

    Mould returns on the same surfaces after cleaning and repainting.

  • Musty odours

    A damp smell in closed rooms, wardrobes and storage areas.

  • Damp wardrobes

    Clothing, shoes and stored items that never feel completely dry.

  • Damage to interiors

    Furniture, finishes, artwork and textiles affected by sustained moisture.

  • Cold but humid rooms

    The thermostat is low, the room is cool, and the air still feels heavy.

  • Humidity after fresh air

    Indoor humidity rises whenever outdoor air is introduced.

Two systems, two jobs

Air conditioning and ONYX NOVA are complementary, not alternatives.

ONYX NOVA does not replace air-conditioning. The AC continues to control temperature; ONYX NOVA independently manages moisture and treats the air.

Air conditioning

  • Primarily controls temperature
  • Dehumidification depends on cooling operation
  • May cause overcooling when used to fight humidity

ONYX NOVA

  • Independently monitors and manages moisture
  • Operates based on humidity demand
  • Filters and treats circulated air
  • Can support controlled fresh-air introduction when properly designed

ONYX NOVA does not replace air-conditioning. The two systems perform different but complementary functions.

How it works

Typical ONYX Core installation concept

Most ONYX NOVA solutions are concealed ducted systems installed separately from the air-conditioning system. ONYX Zenith may also be integrated into an air-conditioning or wider HVAC system where the project design allows.

  • Condensate / fresh air

ONYX Core uses its own engineered return and supply ducts. Where the interior design allows, the ONYX NOVA and AC air paths may use separate sections of the same visible grille, helping preserve a clean ceiling appearance while keeping the systems functionally separate.

Layers

Installation architecture depends on the selected ONYX NOVA solution. Zenith may use an integrated HVAC arrangement following professional engineering review.

Why professional design matters

Equipment cannot be selected on floor area alone.

Two properties of the same size can behave very differently. Selection follows an assessment of the factors below, and is confirmed during design.

  • Moisture load
  • Outdoor temperature and relative humidity
  • Quantity of introduced fresh air
  • Property infiltration
  • Ceiling height and room volume
  • Occupancy
  • Kitchens, bathrooms, spa and pool areas
  • Exhaust systems
  • Zoning
  • Duct routes
  • Available ceiling or service space
  • Static pressure and airflow
  • Target humidity and temperature
  • Operating schedule
  • Integration with AC, FAHU and ventilation systems
