When your warehouse needs a proper HVAC system
- 1
Heat that damages stored stock
Food, pharmaceutical and electronics stock all have storage temperature limits. When a metal warehouse roof bakes under Jeddah's sun, the air inside becomes a direct threat to shelf life and product quality. The solution starts with a survey of the racking layout to find the critical zones.
- 2
Workers overheating in the picking area
Workers in the picking and loading area move constantly under a hot roof. Natural ventilation alone is not enough in summer. We choose between direct cooling and evaporative cooling based on a site survey and the indoor humidity level.
- 3
Warehouse offices that are never comfortable
Supervisor and reception offices have different needs from the large storage hall. Putting them on one system raises cost and weakens performance in both areas. We give the office zone its own system and link it to the warehouse with pressure-control points.
Who it's for
Storing heat-sensitive stock in a warehouse
We locate the critical zone in the racking layout and design an independent cooling system with its own controls, keeping that area at a safe temperature separate from the rest of the warehouse.

We join the project at design stage before the roof closes, mapping cooling zones, ventilation and duct routes to fit the racking plan and loading doors from the outset.

How we work
How we work
- 1
Site survey
We visit the warehouse, measure the internal height, review the racking layout and the positions of loading doors and offices, then map the main thermal zones before proposing any system.
- 2
System design and zoning
We design a system for each zone: central or split units for offices and critical stock areas, and evaporative or mechanical ventilation for the picking area where indoor humidity allows it.
- 3
Duct fabrication and installation
We fabricate round and rectangular ductwork in our workshop from G90 galvanised sheet to the site dimensions, insulate with Armaflex or Kimmco materials, then mount the units, run the copper and connect the control points.
- 4
Start-up and handover
We start each zone separately, measure airflow at multiple points across the warehouse floor, and check that all drain lines are clear before handing over.
A zoned system or unplanned scattered units?
| Alrabih | The usual way | |
|---|---|---|
| Zone design | Surveyed and mapped before fitting | Units added when complaints come |
| Ductwork | Fabricated to site dimensions | Flex duct without calculation |
| Evaporative cooling | Where humidity allows it | Fitted without measuring humidity |
| Sensitive stock | Separate zone with its own control | Left in the general air |
| Copper runs | Mueller, weld-free to 30 m | Multiple welded joints |

What sets this district apart
Most Al Marj warehouses are modern buildings with metal roofs and large open spaces, used for raw materials, finished goods and cargo handling, yet the open design allows little natural airflow because of the high ambient temperature. Metal roofs absorb intense summer heat, so cooling systems need high capacity and strong mechanical ventilation to push cold air across the large spaces.
Al Marj sits in east Jeddah, an expanding industrial zone with modern warehouses and broad spacing between buildings.
Most warehouses here select high-capacity central systems with distributed ducts to effectively cover large spaces.
The AC setup in Al Marj
- 1
High-capacity central system for large spaces
For large unified warehouses, we select a high-capacity central unit with a central control panel managing temperature and humidity.
- 2
Robust distribution ducts with separate control points
Large ducts distribute cold air efficiently, and we add separate temperature control points in each section to manage balance.
- 3
Door loss reduction accessories
We recommend air curtains or air walls at warehouse doors to reduce cold air loss from repeated opening and closing.
Before the visit
Before our visit in Al Marj
- 1
Precise measurement of total space and height
Provide accurate warehouse dimensions including clear roof height and any internal partitioned zones.
- 2
Map door movement and goods flow patterns
Tell us how often doors open daily and where they are, and how goods move through the warehouse so we position units efficiently.
- 3
Check electrical voltage and main breaker
Provide electrical voltage details (220 or 380V) and main breaker capacity, as large systems often need dedicated circuits.

FAQ
Questions about Warehouse HVAC
Is evaporative cooling right for a warehouse in Jeddah?
It depends on indoor humidity levels and the type of stock stored. In well-ventilated open areas where stock is not sensitive to a small rise in humidity, evaporative cooling can work well. The site survey gives a clear answer before any decision is made.
How do you handle the height in tall warehouse bays?
In a tall bay, cool air settles low and hot air rises, which works in your favour when diffusers are aimed correctly at the working level and the racking. We set diffuser angles and positions during design based on the racking height and the movement aisles.
Can cold storage zones link to the rest of the warehouse system?
Cold rooms and freezer rooms run on their own refrigeration systems, which we install as a separate service. What we handle here is the ambient air around those room doors, so warm warehouse air does not rush in when they open, managed by pressure zoning between the two spaces.
Do warehouse air ducts need insulation?
Yes, especially ducts that run close to the hot metal roof. Without insulation, cool air gains heat before it reaches the diffusers and loses much of its effect. We insulate with Armaflex or Kimmco materials and seal joints with Foster sealants to stop air leaks.
Does airflow distribution differ between tall racking aisles and open floor areas?
Yes. In tall racking aisles the airflow path narrows and slows, so we choose directional diffusers that push air along the aisle length rather than spreading it sideways. In open floor areas we use wider-angle diffusers. The angle and position of each diffuser are set at design stage based on the aisle width and racking height.
My warehouse is very large, how do we ensure cold air reaches every corner?
We calculate the cooling capacity based on space volume, then design ducts of sufficient size and install multiple distribution points to reach every area with cold air.
Heat spikes sharply on extreme summer days, can the system handle peak load?
We size the system for the extreme peak temperatures expected in Al Marj, not average, so it handles summer spikes without shutting down or losing performance.
My warehouse opens and closes its doors all day, does that affect cooling?
Yes, repeated door openings cause cold air loss, so we choose a system with extra capacity to compensate, and recommend installing air curtains at the doors.
Are Al Marj's electrical runs adequate for large systems?
Most modern warehouses here have strong electrical runs, but we inspect existing distribution capacity before design and may need to upgrade the electrical circuit depending on system size.
