A Rosenberg ECFanGrid is ideally suited for the use in retrofit projects particularly where a single large radial fan is being replaced.
Dismantling the old fan, reducing it into pieces, is the only manageable method for removal. Further, installing the new fan becomes the an equal challenge when working with single large radial units.
However, when using an ECFanGrid, installation is not an issue mainly due to the modular design, which allows the unit to be built directly on site. Also, a key feature is that the modules fit through standard doors and can be handled by one or two people.
Additionally, Rosenberg offers two ECFanGrid construction options: either mount modules into a pre-defined frame, as illustrated in Fig. 1, or use the Unobox design shown in Fig. 2, which is self-supporting and stackable.
