A rotary regenerative heat exchange assembly comprises (1) heat exchange wheel means including a heat exchange wheel having a rotation axis and rotably mounted for rotation about said axis and means for rotating said wheel about said axis; and (2) cabinet means comprising openings for securing said assembly to a source of relatively cool air and to a source of relatively warm air so that when said assembly is properly located in an operative position in said cabinet means a portion of said wheel intercepts the flow of said relatively cool air and another portion of said wheel intercepts the flow of said relatively warm air, said cabinet means including means for slidably supporting said heat exchange wheel means and an opening so that said heat exchange wheel means can be slid into said cabinet means to said operative position, and at least partially moved out of said cabinet means so that said wheel can be maintained and/or replaced.
