The overall size of the DCS800-EP is slightly larger than the FlexPak 3000 in some cases. However, the FlexPak3000 required more clearance in width and height, so differences in those dimensions are unlikely to be a problem. Depth, however, could sometimes be an issue, especially with the optional Bframe reactor.
Width: four inches of side clearance was required for the FlexPak 3000 to allow room for the control rack to swing open. DCS800 does not have a swing-out control rack so very little side clearance is required.
Height: The FlexPak required more top and bottom clearance for airflow than does the DCS800.
Depth: The depth of the DCS800 is greater in some cases. This may cause an issue if there is very little depth clearance in the existing enclosure.
Table 4, below, compares the dimensions and clearance requirements. (See tables 1 and 2 to determine frame size by model number.)
