Castel Engineering presents mounting systems for air-conditioning installations: galvanised steel rails on black bases for rooftop outdoor units and smaller floor stands. Boards labelled 'ClimClick' and 'OptimalDuct' show line-set trunking, set against blue walls, white vertical slats and black-and-white photos of units mounted on roofs.
