The Unico System is a complete indoor comfort system
that includes an indoor air handling unit and small duct
system. The air handler and duct system were designed to
operate together to provide the proper airflow in every in-
stallation. The conditioned air is supplied through a series
of 2-inch ducts as a stream of air that entrains and mixes
the room air. This process of aspiration produces a more
even temperature distribution in the room.
The Unico 'M' Modular Series air-handling units consist
of various modules that are easily latched together. The
modules can be arranged in a vertical-up-flow, vertical-
counter-flow and horizontal-flow configuration. They can
be combined as a heating-only, cooling-only, or heating
and cooling air handler unit. See Fig. 1.
