When your warehouse needs a proper HVAC system

  1. 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. 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. 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.

  • Building a new warehouse and need HVAC from the start

    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. 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. 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. 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. 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.

  • Rooftop ductwork and an exhaust fan, with Jeddah buildings in the background.
  • Rooftop packaged AC units with rectangular duct transitions, city buildings behind.
  • Insulated rooftop duct run beside a packaged unit, a warehouse roof in the background.
  • A grid of round diffusers in an open-plan office ceiling, mid-construction.
  • An insulated rooftop duct elbow, against a mountainous backdrop.
  • Large insulated ductwork running along a factory ceiling, with workers visible below.
  • A yellow round diffuser mid-installation, with spiral duct and a suspended ceiling grid.
  • Duct insulation wrap in progress on a construction site, bare duct still exposed.

What sets this district apart

Al Qaws warehouses sprawl over land packed with heavy workshops and large industrial equipment, and spaces are often confined between nearby buildings because of zone density. Metal roofs and heat-generating equipment release massive thermal energy, so cooling here must be robust and reliable, any breakdown could halt production or endanger workers. Heat-load calculation includes not just roof and walls but also heat from equipment and industrial processes.

Al Qaws, in east Jeddah, is a dense industrial zone with heavy workshops and warehouses packed with giant equipment.

Heavy industrial warehouses in Al Qaws need very high-capacity central units, often with a backup or secondary unit because of reliance on continuous production.

The AC setup in Al Qaws

  1. 1

    Very high-capacity central system with standby

    Powerful primary unit with connected standby to ensure production never stops due to failure or maintenance.

  2. 2

    Heavy multi-stage industrial filters

    Heavy-duty filters protect the unit from industrial dust and fumes, with scheduled maintenance every two months.

  3. 3

    Reliable ductwork with robust controls

    Sturdy, durable ductwork with industrial-grade thermostats that withstand pressure, humidity and workshop dust.

Before the visit

Before our visit in Al Qaws

  1. 1

    Ask about equipment types and industrial processes

    List the heavy equipment and heat-generating processes, as this significantly affects thermal-load calculation.

  2. 2

    Check if there is room for a potential backup unit

    If you plan a backup unit, check available space on the roof or outside the warehouse for installation.

  3. 3

    Define operating hours and potential maintenance windows

    Tell us full operating hours and whether specific times are available for necessary scheduled maintenance.

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 heavy equipment in the workshop produces massive heat, how does the cooling system account for this load?

We calculate total heat load from roof, walls and operating equipment, and add a large safety margin because heavy workshops often exceed predicted load.

We cannot afford cooling downtime because production stops, what do you recommend?

We recommend a very high-capacity primary unit with a standby unit connected, so if the main one fails the backup switches on automatically, allowing maintenance without downtime.

Industrial dust and workshop fumes may clog filters quickly, what should we do?

We install multi-stage heavy-duty filters and set maintenance every two months to clean or replace them; we may also add an extra air-purification filter depending on fume type.

The warehouse may run 24/7, can the cooling system handle continuous operation?

Yes, but we need a high-quality unit with a powerful compressor and components rated for continuous operation, and regular scheduled maintenance is essential to maintain performance.
