Chiller & AHU installation in Al Hamra

The method depends on the chiller weight, the building height and the space available around the site. The survey determines whether a crane or other equipment is used, and we verify that the roof structure can carry the load before setting the unit on its base.

Chilled water pipes carry cold water through hot, humid, salty air. Without external protection, insulation deteriorates from moisture and salt and loses effectiveness. Aluminium cladding protects the insulation from outdoor air on rooftops and the humid interior air found in coastal buildings like those in Jeddah.

Yes, if the existing ducts are in good condition and match the new unit's connections. At the survey we check the duct opening sizes, the duct condition and the plenum arrangement, and confirm whether part of the network needs adjustment or transition pieces need to be fabricated in our workshop.

After the pipe pressure test we run the chiller and AHUs, measuring air temperature and pressure at each unit's outlets. We adjust dampers and valves to achieve the designed air and water flow to every zone in the building, and record the final readings before handover.

A concrete inertia base adds mass that dampens the chiller's own vibration and holds the unit steady when the compressor starts. Rubber anti-vibration mounts interrupt the path of vibration before it reaches the roof slab. Whether to use one approach or both depends on the site survey, which takes into account the roof structure, the size of the unit and the building design.

Chiller vibration transmits noise to hotel suites. We use very heavy vibration-isolation bases, secure pipes with special flexible hangers, and run acoustic testing before handover.

Coastal humidity is high and condensation threatens ceilings and walls. We wrap every pipe in heavy insulation and secure aluminium cladding, and install drain lines for each unit with meticulous care.

We carefully assess cooling demand with the consulting engineer and select the right chiller capacity. We conduct full pump and balance tests to ensure efficient, even distribution to every AHU.

We install AHU units with high-efficiency filters and advanced control systems. We conduct balancing tests to ensure governed airflow into every corner of each suite.
