Chiller installation in Al Marjan Island 

Chiller 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.

• Hotels need central plants, fresh-air dehumidification, hot water with Legionella control and kitchen extract.
• 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 hotels and serviced apartments, the work concentrates on quiet guestroom fan coils, kitchen and laundry extract, hot-water generation at scale, BMS supervision and phased handover to the operator.

Scope of work

• Review of plant capacity, redundancy and part-load profile so the number and size of chillers matches how the building actually operates through the year.
• 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.

Systems we install

• Chemical dosing and side-stream filtration on the chilled-water loop
• Thermal energy storage tanks where tariffs or loads justify

UAE site and climate challenges

• Hot discharge air recirculating between closely spaced roof chillers raises inlet temperatures further, so layout, screen walls and spacing are checked against manufacturer clearance guidance.
• 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.
• Refrigerant choice, where lower global-warming refrigerants may be preferred by green building assessors but can affect chiller availability, efficiency at high ambient and service technician familiarity.
