Chilled water piping in Al Quoz 

Chilled water piping in Al Quoz: local context

Al Quoz is a long-established industrial and commercial area between Sheikh Zayed Road and Al Khail Road, full of warehouses, workshops, showrooms and creative spaces, alongside staff accommodation. Much of the stock dates from the 1980s–2000s and is now being renovated or converted. Work here is often refurbishment of older buildings rather than new construction. Recent years have seen many units converted into galleries, studios, fitness venues and showrooms.

• Older warehouses often need electrical upgrades, new main distribution boards and power factor correction to support new tenants or processes.
• Conversions to showrooms, galleries or offices require new HVAC systems, often ducted split or VRF, in buildings with limited roof capacity.
• The area is central, so logistics are simple, but streets are busy with trucks and limited parking.

Building types we serve in Al Quoz

For factories and industrial plants, the work concentrates on process cooling and ventilation, heavy LV distribution, hazard-appropriate fire protection and plant that tolerates dust and high ambient temperatures.

Scope of work

• Pipe sizing review against design flows and allowable pressure drop, with velocity checks to limit noise in risers and erosion at fittings.
• Installation of steel or pre-insulated mains, risers and branch pipework with supports, anchors and expansion provisions suited to each route.
• Isolation, balancing and two-way control valves at coils and risers so individual floors or buildings can be maintained without shutting the plant.
• Chemical cleaning and flushing to remove mill scale, debris and welding residue, with water treatment introduced after flushing.

Systems we install

• Pre-insulated buried pipe networks between buildings
• Automatic air vents, drains and air separators

UAE site and climate challenges

• Buried networks in saline or high-water-table ground face corrosion, so pre-insulated systems with protective jackets and sealed joints are used and trenches are backfilled with suitable material.
• Riser shafts open to outdoor air during construction fill with dust and humidity, so insulation is installed only after shafts are closed and pipes are clean and dry, avoiding trapped moisture under the vapour barrier.
• Two-pipe versus four-pipe distribution: almost all UAE buildings need cooling only, so two-pipe is standard, but hospitals, laboratories or palaces needing reheat for humidity control may justify a separate heating loop.
