An air treatment system having an outer heat exchange coil, an inner heat exchange coil spaced-apart from and encompassed by the outer heat exchange coil, seal structure positioned with respect to both coils so that air pulled through the air treatment system by air movement apparatus may flow through the inner heat exchange coil without flowing through the outer heat exchange coil; and in one aspect, an air treatment system having an outer heat exchange coil; an inner heat exchange coil within the outer heat exchange coil; the inner coil spaced-apart from the outer heat exchange coil; the inner heat exchange coil and the outer heat exchange coil defining an inner chamber therebetween; the inner chamber positioned so that air exhaust apparatus above the inner heat exchange coil moves air into the inner chamber for exhausting therefrom by the air exhaust apparatus; air flowing from outside the outer heat exchange coil, through the outer heat exchange coil, and into the inner chamber; and air flowing from outside the housing between spaced-apart ends of the inner heat exchange coil to within the inner heat exchange coil, through the inner heat exchange coil, and into the inner chamber.
