Chiller & AHU installation in Al Wahah

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.

Modern design helps, but we must avoid placing the unit above sensitive areas like meeting rooms or executive offices, and we assess vibration and noise with the engineer to select the right spot.

Wider spaces allow more routing flexibility, but pipes need full insulation and aluminium cladding to prevent condensation and moisture, especially if the external spaces are exposed to direct sun.

Yes, coastal humidity increases the risk of condensation on pipes and units, so we insulate all pipework with thick layers and use aluminium cladding that repels both heat and moisture.

We inspect existing connections and calculate them with the engineer before installation, and if they are inadequate we recommend upgrading the electrical panel or adding a dedicated circuit.
