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
Harat Al Sham is part of old downtown Jeddah, most of its warehouses tucked into ground or upper floors of narrow historic buildings with low ceilings and ageing wiring. Heat is high due to coastal proximity and dense construction, but tight doorways and passages mean installation must be quick with minimal changes; many owners resist any structural alteration. The solution here relies on small units or split systems rather than heavy central ones.
Harat Al Sham in old downtown Jeddah is a zone of narrow, closely built historic buildings with low ceilings and old wiring.
Most stores here are small and embedded in upper or ground floors, using single split units or window condensers instead of central systems.
The AC setup in Harat Al Sham
- 1
Compact split unit
Small stores in Harat Al Sham use one compact split unit matching the low ceiling and tight floor space.
- 2
Window unit as an option
Some very old stores cannot take pipe penetrations, so a simple window unit might be the only option.
- 3
Surface mounting without drilling
The indoor unit mounts on the wall with surface brackets and fasteners only, ducts run along the wall or through existing openings.
Before the visit

Tell us about the building condition and wiring
Briefly describe the building: ceiling height, whether old wiring is safe, and which windows are available for pipe routing.
- 2
Confirm the nearest parking spot
The street is very narrow, so let us know the closest parking or entry point to ease equipment transport.
- 3
Confirm access to the outdoor installation spot
Specify the outdoor location (small balcony, exterior wall, window or roof) and ensure it is easily accessible and safe.

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.
The building is very historic, can you install without drilling or breaking walls?
Yes, we use surface brackets and fasteners, and route pipes through existing windows or openings without altering the original structure.
The ceiling is very low and space is tight, will the indoor unit fit?
We choose a compact unit fitting low ceilings and tight space, and recommend wall-mounting instead of ceiling-mounting if needed.
The wiring is very old, will it handle the new AC?
We inspect the wiring first; if it is weak we recommend installing a separate breaker or upgrading the circuit through a licensed electrician before we start.
The street is very narrow and the entrance is small, how do you get the outdoor unit in?
The outdoor unit is compact and can be hand-carried through narrow streets and small doorways. We agree in advance on the closest parking spot and easiest access route before installation day.
