Abstract: An air handling unit has a first modular cabinet comprising a first profile, a second modular cabinet comprising a second profile that is complementary to the first profile, and the first profile comprises an alignment feature. An air handling unit has a heat exchanger cabinet comprising a first profile, a blower cabinet comprising a second profile complementary to the first profile, a first connector system disposed at least partially on each of the heat exchanger cabinet and the blower cabinet, and the first connector system is operable to releasably secure the first profile to the second profile. An air handling unit has a first modular cabinet comprising a first portion of a first connection system and a second modular cabinet comprising a second portion of the first connection system. A component of the first portion may be least partially received within the second portion.
