Chilled water piping in Al Qusais 

Chilled water piping in Al Qusais: local context

Al Qusais combines a long-established industrial area of warehouses, workshops and trading stores with residential mid-rise blocks, staff accommodation and schools, just north of Dubai International Airport and close to the Sharjah border. Much of the building stock dates from the 1980s–2000s and is being steadily refurbished or replaced plot by plot. It is a working district where trucks, buses and residents share the same streets.

• Staff accommodation blocks need generously sized domestic water storage, hot-water generation, drainage stacks and kitchen extract designed for high, simultaneous occupancy at shift changes.
• Proximity to the airport flight path can restrict crane and mobile-crane heights, so lifting of rooftop chillers and packaged units may need aviation-related permissions and planning.
• Change-of-use projects often trigger fire alarm, sprinkler and hydrant upgrades to meet the current UAE Fire & Life Safety Code before Civil Defence will sign off.

Building types we serve in Al Qusais

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.
• Isolation, balancing and two-way control valves at coils and risers so individual floors or buildings can be maintained without shutting the plant.
• Closed-cell insulation with vapour barrier, aluminium cladding outdoors and labelling with flow direction.
• Strainer and coil bypass arrangements during flushing so debris is collected in temporary screens rather than lodged in new fan coil and AHU coils.

Systems we install

• Pressure independent control valves at fan coils and AHUs
• Energy meters at building or tenant connections

UAE site and climate challenges

• Exposed roof pipework sits in direct sun for most of the day, so it receives thicker insulation and UV-protective aluminium cladding to limit heat gain, stop insulation breakdown and keep supply water temperature close to plant output.
• 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.
• 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.
