OUR ENGINEERING DEPARTMENTS ESTIMATION, DESIGN & DRAFTING DEPARTMENTS:
ABU DHABI OPERATIONS:
Reporting to the Technical Manager, the engineers start with the heat load calculation, selection of the equipment, ducting, refrigerant piping/chilled water piping, to the finalcosting of the project. Our Auto CAD drafting department makes shop drawings from the input they receive from the design engineers. We have a dedicated team of engineers specialised in the selection of AHUs and FCUs, with the latest windows-based software, for the chilled water projects.
Our Abu Dhabi office covers Abu Dhabi and Al Ain territories.We have design, sales and installation /maintenance departments with qualified and experienced graduate engineers, along with necessary support staff. Abu Dhabi maintenance department also carry out 24 hour maintenance jobs.
SALES DEPARTMENT:
MAINTENANCE DEPARTMENT:
All our engineers are experienced in the sales and installations of residential and commercial air conditioning systems. All of them are highly qualified and trained engineering graduates. Installation Department Headed by a graduate mechanical engineer with more than 29 years of experience in the air conditioning field, along with site engineers, we have various eams for the our engineering departments installation and commissioning of DX and chilled water units and we have also our own team for the duct work.
Our maintenance department takes care of the after sales service. We also undertake annual maintenance contract for the air conditioning works. We have good stock for all the necessary spare parts.To make sure that we have prompt response to maintenance reques twe established maintenance departments in Abu Dhabi, Dubai Sharjah, Fujairah and RAS Al Khaima. Our maintenance department works 24 hours a day

CASSETTE TYPE LOW NOISE VORTEX FAN & FRESH AIR INLET
4-WAY AIRFLOW Front air deflectors are adjustable for horizontal or vertical airflow. Smooth airflow can be directed to air condition the whole room or even a particular point for better comfort.
Incorporating with the vortex fan technology as well as optimized air plenum, these units fit neatly into the ceiling and distribute conditioned air through 4 sides of the unit. Fresh air outside can be led into the room, which keeps room air fresh and ventilated. It’s about 15m3/h. (Optional function to build fresh air plenum.)
