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
Vapormist 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-8, and all
VM-10 models except those using 240 V, three-phase power with
SSR control.
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 Vapormist models except those models using 240V/480V/600V/
three-phase power with the SSR control option and drawing more
than 21.7 amps. The SDU-E dispersion box requires an installed
condensate drain line and water seal, provided by installer. See the
following pages for installation instructions.
Mounting the SDU-I and SDU-E
Both SDUs can be mounted on a wall directly above the Vapormist
cabinet or mounted on a wall remote from the Vapormist. Use the
mounting template on the box for correct placement. Two lag bolts
are provided with each fan unit.
