Frame Reinforcement: Technicians are welding additional hollow section steel to the existing AHU/FCU base frame.
On-site Support Work: Welding and grinding are being used to modify the structural platform, likely to improve load distribution or level the unit.
Hot Work Safety: Fire extinguishers are staged on-site, and technicians are following safety protocols during welding.
Ducting Repair: Extensive application of aluminum foil tape to seal the insulation around the duct-to-unit connection.
Condensation Prevention: The sealing ensures a continuous vapor barrier to prevent sweating and air leakage at the inlet/outlet.
Isolator Installation: The corners of the frame are being fitted with vibration isolation pads or protective covers to reduce noise transmission through the building structure.
Base Leveling: Adjustments are being made to the galvanized steel frame to ensure the unit sits correctly on its concrete plinths.
Site Cleanup: Post-welding debris and slag are being cleared to maintain a clean mechanical room environment.
Pipe Alignment: Verification of condensate drain and refrigerant piping alignment following the frame modifications.
