<p>An air handling unit comprises a framework of interconnected elongate frame members 10 in the form of pultruded sections in which fibres are embedded in resin. The fibres may run parallel to each other and to the section longitudinal axis. Additional reinforcing fibres may be provided to define connection points for panels 6 which close off the framework. The unit houses dampers, coils, filters or humidifiers for treating air. The pultruded frame members are of hollow box section (Fig 2, not shown). They may be interconnected by moulded corner pieces (Fig 3, not shown). <IMAGE></p> |
