All SP Series units come as a completely assembled system.  Only the longest units that will not fit on a drop-deck flatbed in one piece have a filter section that needs to be easily connected in the field (no refrigeration work!).  

Optionally, the units can come in several sections that allow for lower weight per section and smaller size.  These are pre-designed sections that have been specifically created to allow for minimized cost and field labor.  See the General Arrangement drawings for the size and weight of the optional sections.  

Specially designed sectioned systems are available for extreme cases.  Contact your Desert Aire Representative for more details.
