Cooling fit for a mosque
Mosque HVAC in Industrial City
In Industrial City in south Jeddah, mosques serve large numbers of workers and staff, and the hot, polluted industrial environment demands the highest cooling system requirements. Alrabih designs powerful systems with high-efficiency filters that withstand dust and extreme heat.

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.

What the work covers
- 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
Industrial City is a very open economic zone with large warehouses and dense workshops emitting continuous heat and industrial dust. Mosques here receive large crowds of workers at prayer times, especially at midday and afternoon prayers, and temperatures reach extreme levels in summer. The air carries dust and pollutants from various industrial processes, adding pressure to the cooling system and filters. Design focuses on very high cooling capacity to handle heavy attendance and extreme heat, with advanced filters requiring more frequent replacement than in other areas.
Industrial City lies in south Jeddah, a wide open economic zone surrounded by large warehouses and heavy workshops.
Industrial City mosques receive very heavy attendance and need much larger cooling capacity than mosques in typical residential areas.
The AC setup in Industrial City
- 1
Industrial-grade cooling unit with very high capacity
Mosques in industrial zones need very powerful cooling units with high capacity that handle heavy crowds and extreme heat.
- 2
Advanced filtration with easy-change filters
We install multi-stage filtration with easy-change filters to capture industrial dust and pollutants, allowing regular inspection and maintenance.
- 3
Precisely distributed ducts for heavy attendance
We design high-precision duct networks that distribute cold air evenly across large halls serving heavy crowds without strong draughts.
Before the visit
Before our visit in Industrial City
- 1
Confirm electrical supply capacity
Confirm the mosque's electrical supply can support a very high-capacity cooling unit, which may require a qualified electrician's inspection.
- 2
Mark the outdoor unit location away from entrances
Choose a location on the roof or external space that places the outdoor unit away from staff entrances and heat from nearby workshops.
- 3
Provide a diagram of the hall and entrances
Send a diagram showing the prayer hall, entry points and existing windows, so we design cold-air distribution that reaches every area evenly.

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.
Our mosque gets hundreds of workers at prayer times; can the AC handle such heavy crowds?
Yes, we design the system with very high capacity to handle both heavy attendance and extreme heat. We size it based on the expected number of worshippers and the extreme temperature in the industrial zone.
Industrial dust is heavy here; do the filters need constant replacement?
Yes, industrial dust accumulates much faster than in residential areas, so we install high-capacity, high-efficiency filters and recommend inspecting them every two weeks and changing them monthly or as needed.
Summer heat here is brutal; how do you ensure the AC doesn't strain or fail?
We select cooling units designed specifically for extreme-heat zones with overload protection systems. We recommend pre-summer maintenance and regular inspections to ensure the system runs efficiently throughout the season.
The mosque's electrical supply is limited; will that affect installing a powerful AC?
The electrical supply may need upgrading before installing the powerful cooling system required. We inspect the existing circuit and advise on necessary improvements to ensure safe, efficient operation.
