Ducted dehumidification · UAE
Concealed units with multi-stage filtration for villas, apartments, hotels, offices, shops and warehouses. We survey, size, install and service them across all seven emirates.
Site survey · sizing · installation · maintenance, UAE-wide
Systems
Every unit sits above the ceiling, runs on its own ducts and filters the air it dries. Choose by the air that needs treating: the air already in the house, the fresh air coming in, or a large volume.
Series R
Dries the air already in the house and returns it through its own supply ducts. For villas and apartments that have enough fresh air.
Series F
Brings in filtered outdoor air, dries it and recovers energy from the exhaust. For sealed towers and villas the AC cannot dry.
Series H
For large volumes: hotels, warehouses, showrooms and indoor pools. Sized to the moisture load, not the floor area.
Series T
Treats the fresh air before it reaches the rooms: filters, dries and exhausts through its own path.
On every system
Three stages in the same airflow that dries the air: a washable pre-filter, a fine-filter stage and activated carbon. Spores, dust and odours leave with the moisture.
The UAE summer problem
Sealed, double-glazed homes trap moisture from showers, cooking and laundry. The AC cools, cycles off and cannot hold a humidity target. By morning the windows are wet and the wardrobe smells.

If two of these sound familiar, a survey is worth it.
Each point answers something UAE owners say about portable units.
The unit sits above the false ceiling. In the room you see a grille and a wall controller, nothing else.
One system reaches every room through the ducts. A portable treats one room, and a villa needs several.
Condensate goes to a plumbed drain. A 20-litre portable can fill its tank in under a day in August.
The compressor runs in the ceiling void, not beside the bed. Portables reviewed in the UAE reach 57 dB.
The same airflow passes a pre-filter, a fine-filter stage and activated carbon, so spores and dust leave with the moisture.
The humidistat holds the setpoint through a six-week summer trip. No tank, no reset, no coming home to mould.
Air leaves the room through a return grille and comes back drier and cleaner through the supply grille. The unit sits above the ceiling, out of sight.
A dedicated return duct draws humid room air into the unit. It never connects into the AC ductwork.
The air passes a cold coil; moisture condenses out and the air leaves drier. Capacity is rated in litres a day and sized to your moisture load.
Condensate runs to a plumbed drain. There is no tank to empty and no hose across the floor.
Three stages: a washable pre-filter, a fine-filter stage and activated carbon. Spores, dust and odours stay in the filters.
Dry, filtered air comes back through the supply grilles. The humidistat holds the setpoint and the unit stops when it is reached.
Four systems, one question: which air needs treating?
Series R · recirculating ducted
For villas and apartments with enough fresh air. Sits in the ceiling void and dries the air already in the house, room after room.
Series F · fresh air with heat recovery
For sealed towers and villas that need fresh air without the humidity it carries. Supplies filtered outdoor air, exhausts stale air and recovers the energy.
Series H · high capacity
For hotels, warehouses, showrooms and indoor pools. Large volumes, continuous operation, integration with the building's HVAC on review.
Series T · fresh-air treatment
For villas, offices and hotels that bring in outdoor air. Treats the fresh air before it reaches the rooms: filters, dries and exhausts.
On every system
A washable pre-filter, a fine-filter stage and activated carbon in the same airflow that dries the air. The controller shows when a stage is due.
Cheapest first. Ours last.
A portable unit is a good tool for one damp room. It is not a whole-home fix.

Spaces
Spaces
Ground-floor damp, jammed doors, wardrobe mould and condensation have one cause. One ducted unit per zone replaces three portables and the daily emptying.
Spaces
Double glazing keeps the heat out and the moisture in. A concealed unit in the ceiling void holds the setpoint, with no tank and no box on the floor.
Spaces
Corridors, spas and indoor pools included. Capacity in litres a day, fresh-air treatment with heat recovery, and a service plan.
Spaces
Retrofit into existing ceilings. No floor units, no tanks, a set humidity for staff and equipment.
Spaces
Door traffic brings humid air in all day. Units sized for the openings keep glass clear and stock dry.
Spaces
Coffee, paper, leather, electronics and archives held at a set humidity with high-capacity units sized by volume and door openings.
Two outcomes per space, measured on the survey and checked at handover.
By space
The same concealed units, sized differently: a villa, a penthouse, a hotel floor, an office, a showroom, a storage facility. Pick your space to see what is measured and what is installed.
From survey to handover, one team.
On site
Humidity readings room by room, a ceiling-void check, duct routes and drain points.
Engineering
Load calculation from the readings, occupancy and fresh air. Never by floor area alone.
Our own team
Dedicated return and supply ducts, a plumbed drain and the electrical connection. Nothing joins the AC ductwork.
Readings report
Setpoints configured, readings recorded, filter schedule and maintenance plan handed over.
A wall controller shows the reading, the setpoint and the filter status. Nothing to switch on in the morning.
Set the humidity you want; the unit runs only while the air is above it.
The panel tells you when the fine-filter stage is due. The pre-filter is washable.
Rated power is published on the datasheet. Running cost at DEWA tariffs follows once we have measured real installations.
Datasheets, duct spigot drawings, electrical loads and BOQ text, all in one place.

Short answers. The full list of questions is on the FAQ page.
It depends on the moisture load, not the floor area: how many people live there, how much fresh air comes in, how many wet rooms, and the ceiling height. A survey measures the humidity room by room and we size from that. The figure is stated in litres a day at 30 °C and 80 % RH, the standard rating condition.
No. The unit runs on its own dedicated return and supply ducts and is never connected into the AC ductwork. The AC keeps cooling; the dehumidifier holds the humidity. The two systems work side by side.
Yes. The humidistat keeps the unit running on its own setpoint and the condensate goes to a plumbed drain, so there is no tank to fill. Leaving the AC on fan or auto mode while away is still good practice, but the humidity no longer depends on it.
Running cost depends on the unit's rated power and on how many hours it actually runs, which the humidistat controls. We publish the rated power from the datasheet and calculate the monthly cost at DEWA tariffs once we have measured real installations. One correctly sized unit under humidistat control replaces two or three portables running flat out.
The compressor and fan sit in the ceiling void or a plant room, not in the room. What you hear is air at the supply grille. The noise figure at the grille comes from the datasheet and we publish it per model.
No. Existing mould has to be removed first, and mouldy gypsum often has to be cut out and replaced. The system then keeps the humidity at a level where it does not come back, and the filtration takes spores out of the air.
Our own team surveys, designs, installs and commissions the system. Installation time depends on the duct runs and the ceiling access, and we confirm it in the quote after the survey. You get a readings report and a maintenance plan at handover.
Yes. Every unit passes the same airflow through a washable pre-filter, a fine-filter stage and activated carbon, so dust, spores and odours are removed as the air is dried. The controller tells you when a filter is due.
