When you need evaporative cooler duct
- 1
A large workshop or warehouse
Large industrial spaces get very hot in Jeddah summers and split units are expensive to run there. An evaporative cooler with distribution duct brings air to work areas at lower running cost, provided the space is ventilated and not sealed shut.
- 2
A majlis tent or seasonal space
Outdoor majlis areas and seasonal tents do not suit split AC units because of the structure. Evaporative duct delivers a cool air stream as long as the space is open enough for air changes, which the survey confirms.
- 3
Old duct with poor airflow
Old sheet duct cracks over time and air leaks from the joints before reaching the space. On site we check whether the problem is leaking duct, poor distribution, or the cooler size itself.
Who it's for
Need to cool a large workshop at reasonable running cost
We survey the workshop and check its ventilation, then run galvanised duct from the roof cooler to the work areas with exhaust openings that keep air moving through the space.
Ask on WhatsAppYou have an outdoor majlis that needs seasonal cooling
We check how open the majlis is and assess its structure, then design the duct route and exhaust openings so cool air reaches the seating area without humid air building up inside.

- Weatherproof roof collar fitted
- G90 galvanised duct runs
- Branch and air outlet connections
- Exhaust openings for air changes
- Airflow check after start-up
How we work
How we work
- 1
Site survey first
We visit, measure the space and check how open it is, because evaporative cooling needs enough ventilation; without it humidity rises inside and the cooling effect drops.
- 2
Plan the duct route
We plan the main duct run, branches, air outlet positions and exhaust opening locations, and show you the layout before any work starts.
- 3
Install duct and seal roof
We open the roof, fit and seal the collar against leaks, then run the galvanised duct and hang it on proper supports so it does not sag.
- 4
Start-up and test
We run the evaporative cooler and check that air reaches every outlet and that the exhaust openings are working so fresh air is visibly moving through the space.

What sets this district apart
Al Baghdadiyah Al Sharqiyah has modern, spacious buildings, villas, hotels and some commercial complexes, with exposed, safe rooftops for work. These wide spaces and modern layouts make evaporative duct a practical choice for open areas, large corridors and light warehouses, though Jeddah's hot, dry summers mean evaporative cooling may not deliver the results you need in all cases.
Al Baghdadiyah Al Sharqiyah lies in modern central Jeddah, a district of spacious, open buildings with safe rooftops for installation work.
Most modern buildings here can accommodate duct runs from the roof because the architecture allows sufficient space on rooftops and in corridors.

The cooler sits on a safe, exposed roof with water discharge pipes connected safely and securely.
Before the visit
Before our visit in Al Baghdadiyah Al Sharqiyah
- 1
Survey your roof and measure the space
Check that your roof can bear the unit and duct weight, and tell us the floor area you want to cool.
- 2
Identify where water discharge will go
Pick where the evaporative water runoff will drain from the roof or building side, and ensure it will not cause problems for neighbours.
- 3
Check the electrical connections
Confirm your electrical panel is close to the roof and that the circuits are safe for running a powerful fan.

FAQ
Questions about Evaporative (desert) duct installation
Does evaporative cooling work in Jeddah in summer?
Evaporative cooling relies on water evaporation and weakens when humidity is high. In Jeddah, humidity is higher near the coast and lower inland. The survey decides whether the space and the season are suitable, which is why we do not start before visiting the site.
Why do exhaust openings matter as much as the duct runs?
An evaporative cooler pushes fresh air in continuously. Without an exit path, humid air builds up inside and the felt temperature rises. Properly sized exhaust openings keep air moving through, not piling up, and that is the core of how this type of cooling works.
What sheet do you use for the duct?
We use G90 galvanised steel sheet, which resists rust in Jeddah's humid and salty air. The duct sections are formed in our workshop before being taken to site, then hung on supports along the run to stop them sagging.
Can one cooler supply duct to more than one area?
Duct can be branched from one unit to more than one outlet, but each branch reduces the airflow at every opening. The survey decides whether the cooler has enough output for the total area, or whether a separate unit for each wing is the better answer.
Can evaporative cooler duct run through a false ceiling?
Evaporative cooling depends on continuous air movement and exchange, which requires exhaust openings in the same space the duct serves. A false ceiling restricts that flow unless dedicated openings lead air out of the building. The site survey decides whether the structure allows it, because the duct run and the exhaust are designed together as one system, not separately.
Is evaporative cooling suitable for my villa in Al Baghdadiyah Al Sharqiyah?
It depends on your space size and local humidity levels. Our team visits and tests whether evaporative cooling will work in your area's conditions before proceeding.
Our building roofs are modern and safe, but how do you prevent water leaks where the duct breaks through?
We open and seal the roof carefully against rain and dust before fixing the duct and the rooftop cooler unit.
Does Jeddah's extreme summer heat reduce evaporative cooling's effectiveness?
Yes, evaporative cooling works best when humidity is low and heat is moderate. In fierce summer heat, it may not reach the cooling levels you expect.
Do the electrical circuits in Al Baghdadiyah buildings handle the power demand for the fan?
We recommend checking your electrical panel before installation to ensure the circuits can handle both the fan and the cooler unit together.
