Reducing the need for costly demolition or helicopter expenses, the Rapid Knock-Down (RKD) air handler is designed to be delivered to the jobsite in sections matched to the building’s minimum opening, to allow for easier installation into tight or hard-to-reach spaces. The technology meets an increasing need for retrofitting buildings with severe ingress constraints. The air handler allows building owners to realize the benefits of new, more efficient, and reliable technologies while minimizing building demolition costs and downtime, the company said. The unit arrives at the jobsite in shrink-wrapped sections that are matched to the sizes of the building’s opening. Panels and frames are easily removed, and fasteners, gaskets, and sealants ship with the unit along with documentation. The unit is then installed in the allowable space and is warranted as if installed as one piece. According to the manufacturer, the air handler is made easier to assemble providing factory-supplied blueprints and instructions to walk the installer through the process, and contractors can visit the factory and participate in hands-on training on unit disassembly and assembly, to become a certified installer.
