Airmaster Equipment Emirates was selected to supply grilles and diffusers for the Grand Hyatt project after intense competitive technical and price evaluation, says a spokesman for the Ajman-based manufacturer of air terminal devices.

"The consultant Arkiteknik International visited our manufacturing facilities in Ajman for further evaluation of our quality control procedures, testing procedures and the technical expertise required to fabricate curved and special shape air terminal devices," the spokesman adds. "In order to ensure perfect co-ordination and fit, Airmaster seconded technicians to the project to carry out accurate measurements, prepare templates and install them correctly. This special assistance ensured that work progressed according to plan and without a hitch, even though thousands of metres of linear slot diffusers and curved ones of various curvatures and chord lengths were supplied."

He continues: "Steady growth, characterised by high quality standards and productivity, is the hallmark of Airmaster. Our technical expertise is backed by certificates from the Intertek Testing Laboratories, US. Airmaster has also been certified to ISO 9002 since 1997 and its quality management system meets international standards."

Airmaster's modern powder coating facility is fully equipped and supported the Grand Hyatt project with standard and special colours. For better coordination and matching finishes, the contractor also assigned to Airmaster the procurement and finish painting of other types of diffusers not covered in Airmaster's range of products. Round diffuser cones in plain aluminium were obtained from associated companies from Europe and assembly and a matching colour-finish were carried out at the Ajman facility.

Commenting on the company's area of expertise, the spokesman says: "Air distribution is one of the four key factors determining the effectiveness of an air-conditioning system, the other three being temperature, humidity control and cleanliness.

"Air distribution, however, is often paid the least attention. Even if the other three parameters are well controlled, poor air movement results in an inefficient air-conditioning system.

"Air terminal units contribute not only to the physical comfort of occupants but also to the aesthetics of the environment, combining the technical requirements of the mechanical engineer and the creative concepts of the architect and the interior designer."
