Innovative Unit Base Desien
On the inside a high-tech composite material will not rust and
incorporates a sloped drain pan which improves drainage and helps
inhibit mold,algae and bacterial growth. On the outside metal base rails
provide added stability as well as easier handling and rigging.
Convertible Duct Configuration
IN Unit is designed for use in either downflow or horizontal applications.
Each unit is converted from horizontal to downflow and includes two
horizontal duct covers. Downflow operation is provided in the field to
allow vertical ductwork connections. The basepan seals on the bottom
openings to ensure a positive seal cin the vertical airflow mode.
