The optional polytube adapter is designed to adapt suspended Model UDBP and
UDBS blower type unit heaters for use with polytube ductwork. Directly in line
with the heater discharge, the adapter is installed on the front of the heater and is
equipped with a collar for attaching the field-supplied polytube.
The most common application of polytube ductwork for distribution of tempered
air is in greenhouses. Polytubes are also used in industrial buildings to improve
operating efficiency by recovering stratified air and reducing the need for com-
plete area heating.
