Chiller installation in Al Majaz: local context
Al Majaz surrounds Khalid Lagoon and Al Majaz Waterfront in central Sharjah, a district of high-rise residential towers, hotels, offices and retail that grew mostly from the 1990s to 2010s. Its lagoon-front towers are some of the city's most recognisable, and many are now in their second cycle of MEP upgrades. Streets are busy and plots are tightly packed.
- Lagoon proximity means humid, salt-bearing air, so cooling towers, condenser coils, roof pipework and steel supports need corrosion protection and regular inspection.
- Refurbishment of occupied towers involves replacing chillers, pumps and risers floor by floor, with coordinated shutdowns agreed with building management and SEWA where supplies are affected.
- Limited street parking and loading space mean materials arrive in small loads and are moved by hoist or service lift during agreed hours.
Building types we serve in Al Majaz
For malls and retail centres, the work concentrates on large-volume air handling, tenant-ready chilled water or refrigerant capacity, smoke extraction for atriums and car parks and food-court exhaust.
Approvals and authorities in Al Majaz
Chiller installation in Al Majaz sits within Sharjah's regulatory framework. The authorities you will meet are:
- Sharjah Municipality (SM)
- Sharjah Civil Defence (SCD)
- Sharjah Electricity, Water & Gas Authority (SEWA)
- ASHRAE standards (62.1, 90.1) (ASHRAE)
Scope of work
- Rigging and lifting plans for heavy chillers onto roofs or into basements, coordinated with crane availability and site logistics.
- Header, bypass and expansion arrangements with air separators, chemical dosing pots and make-up water connections.
- Plant manager and BMS integration for sequencing, staging and alarm reporting, followed by manufacturer start-up and performance verification.
- Refrigerant leak detection and plant-room ventilation where water-cooled machines sit indoors, wired to alarm and to start the emergency extract fans.
Systems we install
- Water-cooled centrifugal chillers with cooling towers
- Chiller plant managers sequencing machines on load
UAE site and climate challenges
- Air-cooled chillers lose capacity as condenser inlet air rises, and UAE design conditions around 46 to 50°C mean machines must be selected for that ambient, not catalogue ratings at 35°C, or the plant will fall short on peak days.
- Dust and sand clog condenser coils and reduce heat rejection, so coil cleaning access, coatings for coastal sites and a planned cleaning regime are built into the handover.
- Air-cooled versus water-cooled: air-cooled needs no cooling tower or water treatment and suits most towers, while water-cooled is more efficient but needs make-up water, treatment and more maintenance.

Frequently asked questions
Which authorities approve chiller installation in Al Majaz?
Approvals in Al Majaz typically involve Sharjah Municipality, Sharjah Civil Defence, Sharjah Electricity, Water & Gas Authority and ASHRAE standards (62.1, 90.1). Exact routes depend on the plot, the master developer and whether the site sits in a free zone, so we confirm the authority matrix during mobilisation and prepare submissions accordingly.
Does Manolia work in Al Majaz?
Yes. Al Majaz is in Sharjah, roughly 20–60 minutes from central Dubai depending on traffic. Site teams are mobilised from our Dubai headquarters with supervision, QA/QC and HSE staff assigned to each project.
Why is the chilled-water delta-T important?
Delta-T is the temperature difference between supply and return chilled water. When it is lower than design, pumps move more water to deliver the same cooling and chillers run inefficiently. Correct coil selection, two-way control valves and balancing maintain delta-T, and Manolia verifies it during commissioning.
