HVAC installation in Al Marjan Island 

HVAC installation in Al Marjan Island: local context

Al Marjan Island is a group of reclaimed islands off Ras Al Khaimah's coast developed for resorts, hotels and residential towers, with major hospitality projects under way. Building stock is dominated by hotels and high-rise residential. Several large integrated resort projects are under construction, bringing high-rise hotel and residential towers to what was previously a low-rise emirate, and with them the full range of tower MEP requirements such as pressure zoning, stair pressurisation and high-capacity fire pumps.

• Island location means extreme salt exposure, so marine-grade equipment and corrosion protection are essential.
• Approvals typically involve the master developer NOC before municipality, Civil Defence and Etihad WE.
• Access over the causeway and limited laydown space on the island mean deliveries of large plant must be scheduled and staged carefully.

Building types we serve in Al Marjan Island

For high-rise towers, the work concentrates on pressure-zoned water and drainage stacks, riser and plant-room coordination, stair pressurisation and a cooling source sized for diversity across dozens of typical floors.

Scope of work

• Installation of AHUs, fan coil units, VAV boxes and fresh air handling units with vibration isolation, condensate drainage and service access.
• Chilled-water or refrigerant pipework installation with pressure testing, flushing and insulation sealed against condensation in humid ceiling voids.
• Toilet extract, car park ventilation and general exhaust systems sized to keep negative pressure where odours and fumes are generated.
• Controls wiring of thermostats, sensors and actuators linked to the BMS so zones can be scheduled and monitored centrally.

Systems we install

• Ceiling-concealed and floor-standing fan coil units
• Variable air volume boxes for open-plan offices

UAE site and climate challenges

• Sand-laden air quickly clogs filters on AHUs and fresh-air intakes, so intakes are placed away from roof edges where possible, fitted with sand louvres and given accessible pre-filters.
• Equipment on roofs faces direct sun and high ambient air, so condensing units are selected for high-ambient operation and spaced to avoid recirculating hot discharge air.
• Heat recovery on fresh air adds capital cost and plant space but reduces cooling load significantly in buildings with high fresh-air demand such as hotels, gyms and clinics.
