You may have noticed some of the pictures we have with these air handlers in the wall and the grey flooring. These units were made for Boston. Later, the same customer wanted additional units for Boston as well as their facility in Slidell, Louisiana. These have butyl rubber flooring and cooling is handled through vents in the floor. This is different from how we normally do things, but demonstrates our ability to custom build modules for any purpose.
This picture is of the Slidell units installed. The Boston units were deployed indoors.
