Industrial cooling done right
Factory HVAC in Al Salihiyah
Factory HVAC in Al Salihiyah, east Jeddah, must handle both equipment heat and coastal humidity at once. We design a system that keeps temperature steady and humidity low throughout intensive working hours.
- Industrial ventilation
- SMACNA ducting
- Shift-planned maintenance

When does a factory need a specialist system?
- 1
Machine heat exhausting the workers
Compressors, motors and furnaces push out steady heat that scattered split units cannot handle. We assess every heat source on site and design a system that removes that heat and delivers cooled air precisely where people work.
- 2
A high roof that traps hot air
Hot air rises and collects under the roof while workers suffer at floor level. Evaporator positions, airflow angles and unit sizing all depend on the ceiling height and building shape, and the site survey decides each of these.
- 3
Production dust destroying equipment
In wood, metal and plastic factories, coarse dust enters units and damages compressors and coils. We select equipment suited to industrial environments and design air paths that separate cooling air from contaminated process air wherever possible.
Who it's for
Building a new factory that needs HVAC
We join at design stage to fix unit positions, duct routes and extraction before the roof is cast and machines are installed, so the system is built into the structure from the start.
Ask on WhatsAppExisting factory where heat is hurting output
We visit during live production, measure heat at its sources, and design additions or replacements that fix the problem without a long shutdown of your lines.

What the system covers
- Survey of heat and process
- Cooling, ventilation and extraction design
- Round and rectangular duct fabrication
- Unit installation, connections, plenums
- Maintenance around shift patterns
How we work
How we work
- 1
Industrial site survey
Our team visits the factory during operation to measure actual heat from machines, map worker zones and critical processes, record ceiling heights and identify possible duct routes.
- 2
System design
We design central plant, distributed units or a combination to suit the factory, and fix the positions of extraction and ventilation units, duct sizes and damper locations before you approve the work.
- 3
Fabrication and installation
We fabricate duct in our own workshop from G90 galvanised or aluminium sheet to SMACNA standards, run Mueller copper in runs of up to 30 metres without welded joints, mount units and insulate pipework with Armaflex and Kimmco materials.
- 4
Commissioning and scheduled maintenance
We commission the system, check airflow distribution, refrigerant pressure and damper balance, then set up a preventive and corrective maintenance contract timed to fit around your production shifts.
Designed system or random units?
| Alrabih | The usual way | |
|---|---|---|
| Heat analysis | Measured during live operation | Visual guess only |
| Ducting | G90 sheet to SMACNA standards | Off-the-shelf, unsized duct |
| Extraction | Designed with the cooling | Standalone fans, uncoordinated |
| Maintenance | Scheduled around shifts | Only when it breaks |
| Copper runs | Mueller, no welds, 30 metres | Multiple welded joints |

What sets this district apart
Al Salihiyah houses food, chemical and assembly factories with medium-height ceilings and limited natural ventilation. High coastal humidity adds to the cooling load because equipment needs cooling and dehumidifying at once, and salt and moisture degrade outdoor-unit efficiency. The system must handle heavy thermal loads and excess humidity together, and requires regular maintenance to fight coastal corrosion.
Al Salihiyah lies in coastal east Jeddah, a zone of medium-sized factories near the sea with high seasonal humidity.
Most factories here have central cooling units or small chillers with basic ductwork.
The AC setup in Al Salihiyah
- 1
Small chillers with distributed ducts
Medium-sized factories in Al Salihiyah often need a small chiller connected to basic ductwork distributed across the floor or ceiling.
- 2
Ventilation units with dehumidification
Because of high coastal humidity, we install ventilation units that remove excess moisture from recirculated air.
- 3
Salt-resistant protection for outdoor units
Outdoor units are chosen with salt-resistant coatings or treatments to fight coastal corrosion.
Before the visit
Before our visit in Al Salihiyah
- 1
Mark equipment and heat-producing processes
Show us where the heavy equipment and heat-generating processes are located before the visit.
- 2
Ensure access to outdoor space and ceilings
Make sure our team can reach the outdoor space for unit placement and the ceilings for ductwork runs.
- 3
Provide any previous maintenance records
If existing cooling units are in place, send us their maintenance history so we understand the current condition.

FAQ
Questions about Factory HVAC
Can you cool just the worker zones without cooling the whole factory?
Yes, and we do it often. We design spot cooling for workstations or worker walkways using independent units or directed duct runs, rather than trying to cool the entire building volume. The right approach depends on the site and the process, and the survey decides it.
How do you handle heavy industrial dust in Jeddah?
We select units with a protection rating suited to the industrial environment and route airflow away from dust sources where the layout allows. In scheduled maintenance we inspect and clean coils, compressors and filters before deposits build up and affect unit performance.
Do you fabricate the large ducts a factory needs?
Yes, in our own workshop we fabricate round and rectangular duct to any size the design calls for, from G90 galvanised or aluminium sheet to SMACNA standards, including plenums, transitions and dampers needed to control air distribution.
Can you do maintenance between production shifts?
Yes, when we set up the preventive maintenance contract we agree times that fit your production schedule, whether between shifts or on rest days. The aim is that production lines are never stopped because of maintenance work.
What is the difference between process ventilation and worker-zone air conditioning?
Process ventilation targets heat and fumes produced by machinery and production lines, using exhaust fans and calculated fresh-air inlets sized to the heat load at each source. Worker-zone air conditioning aims to maintain a tolerable temperature at floor level without cooling the full volume of the building. A site survey of each factory decides which approach fits each area.
Does coastal humidity affect our cooling efficiency?
Yes, high humidity increases the load. We choose units with extra capacity and design that handles dehumidifying alongside cooling.
Salt and humidity cause rust on outdoor units, how do you protect them?
We choose units with salt-resistant coatings or special treatment for exposed parts, and recommend servicing every three months to fight corrosion.
Our chemical factories need specific cooling, how do you design for that?
We ask about your chemical processes and required temperatures before design, and select units and heat capacity matched to your material and process.
How do you work with medium ceilings and irregular spaces?
We calculate distribution based on the space's shape and heat zones, using flexible ducts and precisely positioned outlets to ensure even cooling.
