SDU-I:
Provides instant, internal absorption
The Space Distribution Unit Internal Absorption
(SDU-I) disperses humidity with no visible vapor trail
or wetness, making the HUMIDI-TECH
®
with an
SDU-I ideal for use in finished spaces. When room
RH is 40% or less, the SDU-I fan mixes room air
and steam to ensure complete absorption before
discharge as humidified air. The SDU-I is available
for models VM-2 through VM-10.
SDU-E:
For higher capacity units or remote mounting
The Space Distribution Unit External Absorption
(SDU-E) mounts either directly on top of
the HUMIDI-TECH cabinet or remotely within a
space, providing application flexibility. The SDU-E is
available for models VM-4 through VM-34.
Mounting the SDU
The SDU may be mounted on a wall above the
HUMIDI-TECH cabinet or mounted on a wall remote
from the HUMIDI-TECH. Use the mounting template
on the box for correct placement. Two coach screws
are provided with each fan unit. (See Page 5 for
mounting instructions.)
