Chilled water piping in Dubai Investments Park (DIP) 

Chilled water piping in Dubai Investments Park (DIP): local context

Dubai Investments Park is a large mixed-use development off the Emirates Road near Jebel Ali, combining industrial plots, warehouses and cold stores with residential, retail and education buildings. It has been one of Manolia's busiest areas: the firm delivered MEP for a 19-factory industrial complex with HQ, HVAC for a driving centre of six buildings, HVAC for a mall and HVAC for a cold store here.

• Factories and warehouses need high electrical loads, process ventilation, compressed air and large-scale sprinkler or hydrant systems, coordinated with racking heights and roof structure.
• Cold stores require insulated panels, refrigeration plant, vapour barriers, anti-condensation measures at doors and careful control of floor heave and defrost drainage.
• Dust from surrounding desert and construction sites clogs condenser coils and filters, so maintenance access and filter selection are planned for frequent cleaning.

Building types we serve in Dubai Investments Park (DIP)

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.
• Chemical cleaning and flushing to remove mill scale, debris and welding residue, with water treatment introduced after flushing.
• 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

• Expansion vessels and pressurisation units
• Energy meters at building or tenant connections

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.
• Large temperature differences between installation in summer heat and cold operating conditions cause expansion and contraction, so anchors, guides and loops are positioned to protect long risers, branch take-offs and equipment connections.
• Pressure independent control valves versus manual balancing valves: PICVs cost more per coil but simplify balancing, keep flows stable as loads change and help protect the system delta-T over the building's life.
