DoubleTree by Hilton Resort & Spa Marjan Island is a 701-room hotel and leisure destination which enjoys a prime location on the trunk of Marjan Island, a cluster of five man-made islands in the upscale area of Al Hamra, Ras Al Khaimah. As one the first hotels to open on the prestigious Marjan Island, it was a development of strategic importance to Hilton Worldwide, Al Marjan Island (AMI) Company, and Ras Al Khaimah tourism.

Taqeef had previously worked on HVAC projects with the development’s contrractors – Al Ali Contracting and ATKINS. They were looking for an A/C supply partner who could meet Hilton International standards and had the design and technical capability to engineer innovative and bespoke cooling solutions. The project’s size and scope also required a partner with sufficient infrastructure and stock-holding to ensure on-time, on-budget delivery and exceptional after-sales service.


Originally the development had been designed for a chiller system. However, Taqeef recommended converting it to a VRF system which would reduce service costs, reduce power consumption, reduce indoor unit sizes and reduce noise levels. It would also provide independent systems for added reliability, allow heating and cooling simultaneously for added comfort, and save on service area and mechanical room space.

The benefits made this system the obvious choice, however, the challenge came in engineering a VRF solution that could meet Hilton International’s specification standards.


Taqeef’s technical team – working in partnership with our international brand partners – adapted the VRF units to include a leak detection system for every room. The individual leak detectors provided optimum safety and were compatible with the building management system (BMS), HILTON International standards and covered by Taqeef’s 10-year warranty guarantee.

We co-ordinated a phased installation plan with the development team and Taqeef engineers rigorously tested every installation before each building was handed over individually.

Our innovative technical solutions provided the client with a bespoke, best-fit HVAC system that exceeded expectations on efficiency, reliability and safety. While our superior service and after-care provision cemented our reputation as the go-to supplier for commercial A/C solutions throughout the region.
