At Precisa Techno Trade Ltd., I designed HVAC systems for pharmaceutical facilities, including GMP-compliant cleanroom and containment environments. I prepared load calculations, BOQs, clarification sheets, and AutoCAD drawings.
I also designed cleanroom airflow strategies using HEPA filtration, CAV and VAV controls, and pressure cascades. I coordinated ancillary equipment such as pass boxes, dispensing booths, and LAF units with the overall HVAC design.
At Tritech Building Service Ltd., I worked as an HVAC Sales Engineer, conducting cooling load calculations and advising clients on HVAC-R equipment selection. I developed practical knowledge of chillers, AHUs, FCUs, and dehumidifiers.
At Walton Hi-Tech Industries PLC., I designed VRF and FCU components using SolidWorks 3D, producing 3D assemblies and fabrication drawings. I also supported sheet-metal production workflows and prepared BOQs for system components.
