Cooling fit for a mosque
Mosque HVAC in Al Shati
Mosque cooling in Al Shati must combine cooling power with easy maintenance in a very humid coastal setting. Alrabih designs systems that endure heat, salt and moisture whilst keeping noise low during worship.

When a mosque needs a specialist approach
- 1
Heat reaching the back rows
Cold air pools near the units and never reaches the back of the hall. In Jeddah's humidity, worshippers in the far rows feel the heat even with the system running. That is a design problem, not a unit fault.
- 2
Noise that disturbs prayer
Unit noise in a quiet hall distracts worshippers and breaks concentration. The right unit type, its position and the air velocity setting all reduce noise to the lowest possible level, and those choices are made at the survey.
- 3
A dome or high ceiling that traps heat
Hot air rises and collects under the dome, so the breathing level stays warm even with large units running. We set diffuser angles and air paths at the survey to push that hot layer out rather than cool over the top of it.
Who it's for
Building a new mosque that needs AC from the start
We join the design stage to fix duct routes and unit positions before ceilings are closed, so the installation is clean and efficient with no remedial work needed later.
Ask on WhatsAppYour existing mosque cools unevenly across the rows
We survey the existing system, find the cause of uneven distribution and propose changes to the airflow paths or units without disrupting the mosque.

- Hall survey and airflow mapping
- Ductwork to SMACNA standard
- Units fitted at surveyed positions
- Airflow check across the rows
- Contracts scheduled between prayers
How we work
How we work
- 1
Mosque survey
We visit the mosque outside prayer times to measure the hall, ceiling height and dome, and agree diffuser positions, duct routes and unit locations before any work begins.
- 2
Design and fabrication
We design the system from the survey data and fabricate the ducts in our own workshop from G90 galvanised sheet, then prepare them for installation.
- 3
Installation at agreed times
We coordinate with mosque management to work between prayers or at times that do not interrupt activities, and we leave the hall clean at the end of each working day.
- 4
Testing and handover
We run the system and measure air distribution at the front and back rows and sound levels, adjusting the balance until comfort is even across the whole hall.
Designed for a mosque or units placed at random?
| Alrabih | The usual way | |
|---|---|---|
| Air distribution | Even across every row | Cold front, hot back |
| Sound | Assessed at survey | Not considered |
| Dome and high ceiling | Planned airflow paths | Hot layer left above |
| Maintenance | Scheduled between prayers | Visits that disrupt use |
| Startup scheduling | Programmed before each prayer | Manual, inconsistent start |

What sets this district apart
Al Shati is a modern coastal northern area with mosques in residential towers and upscale neighbourhoods, prayer halls that are deep and open to humid, salt-laden sea air. Humidity reaches very high levels most of the year, and salt deposits on every exposed surface, so the system must combine very high dehumidification capacity with robust, corrosion-resistant metal parts and frequent short-interval maintenance to prevent decay and blockage.
Al Shati is a highly coastal neighbourhood in north Jeddah very close to the sea, home to modern mosques in residential towers with deep prayer halls directly exposed to sea moisture and salt.
Al Shati mosques require powerful central cooling systems with very high dehumidification capacity and salt-resistant metal components.
The AC setup in Al Shati
- 1
Central system with exceptional dehumidification
The system combines powerful central units with very high dehumidification and outlets distributed across hall depth and dome height.
- 2
Salt and rust-resistant materials and coatings
All metal parts, ducts and outdoor units use specialised coatings and alloys designed to resist salt and high moisture.
- 3
Multiple elevated drainage points
Ducts and outlets are fitted with multiple drainage points elevated from floor level to prevent pooling of water, salt and dirt.
Before the visit
Before our visit in Al Shati
- 1
Identify the outdoor unit location on roof or high balcony
Confirm a safe elevated spot for the outdoor unit where the team can access and service it regularly without hazard.
- 2
Measure hall height, dome and full depth
Calculate the full height from floor to dome and the complete depth from entrance to far wall so the system design covers every spot.
- 3
Plan an intensive maintenance schedule before installation
Agree with mosque management on a monthly or bimonthly maintenance schedule from the start, with clear steps for drainage, cleaning and inspection.

FAQ
Questions about Mosque HVAC
How do you make sure the far rows get enough cooling?
At the survey we set diffuser angles, air velocity and duct routing so cold air travels to the last row. After installation we measure the temperature difference between the front and back rows and adjust each diffuser's balance until that difference is as small as the space allows.
Can you work in a functioning mosque without disrupting prayers?
Yes. We agree a phased schedule with mosque management in advance and divide the work into sessions between prayers. Before each call to prayer we lift tools, cover any temporary openings and return the hall to a usable state, then resume afterwards.
What type of ductwork do you use in prayer halls?
We fabricate ducts in our own workshop from G90 galvanised sheet, round or rectangular as the design requires. We use Armaflex and Kimmco insulation and Foster sealants to limit heat gain and keep sound transmission through the ductwork as low as possible.
Can the system be set to start just before each prayer time?
Yes. The controls on Carrier, YORK, General, Midea, Gree and Smart Gold units support scheduled start and stop times. At the survey we confirm the scheduling options for the chosen units and programme the timings at handover, so the hall is already cool when worshippers arrive.
Can we cool only part of the hall when fewer people attend?
Yes, if the system is designed in zones. We divide the hall into sections, each with its own unit or closable outlets, so you run the front rows alone when few people attend and the whole hall for Friday prayer and occasions, cutting power use without affecting worshippers.
Sea salt affects cooling systems, can your system handle this harsh environment?
Yes, we select high-grade salt and moisture-resistant materials and coatings, and recommend intensive maintenance every month to two months.
Humidity here is very high, does it affect cooling efficiency?
We select units with exceptional dehumidification capacity that prioritise moisture removal first, then cooling, for better comfort and sustained cooling power.
The prayer hall is very deep and tall, how do you deliver cooling to all corners?
We distribute outlets and flow rates across the depth and height of the hall and dome to cover all areas without dead zones or harsh cold spots.
Can your team access the outdoor unit in tall residential towers?
Yes, we visit the site to identify the best safe location for the outdoor unit, whether on roof or high balcony, and confirm our equipment suits the height and access.
