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 45% 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
The Space Distribution Unit External Absorption
(SDU-E) is designed for higher capacity dispersion.
The SDU-E is available for all HUMIDI-TECH
models except Models VM-16 through VM-34 using
three-phase 400 V power with the SSR control
option.
Mounting the SDU-I and SDU-E
Both SDUs may be mounted on a wall directly 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.
Note: See the following pages for more
information about SDU-I and SDU-E.
