Water Mist System
The MVU misting system is used for knocking down suspended gases, providing
additional cooling during ventilation operations and protection of exposures. It can also
be used for decontamination purposes.
Misting Ring:
1.5” diameter stainless steel, 12 nozzles
Flow Rate:
450 lpm @ 7 bar (130 GPM @ 100 psi)
Reach:
40 meters (130 feet)
Droplet Size:
200 microns
Supply:
Central

Misting Ring
A misting ring made from 1 1/2“ diameter stainless steel tubing is mounted forward of
the propeller inside the ventilator-shroud. A total of twelve evenly spaced, 65 degree
spray pattern nozzles on the ring provide a homogenous water fog.
The air stream generated by the ventilator is utilized to transport the water vapor. At a
flow rate of 3490 liters/minute and a delivery pressure of 7 bar the reach of the stream is
over 40 meters.
The finely dispersed droplets of the water vapor absorbe heat, inert fumes, and wash-
down hazardous vapors. Flow rates may be decreased or increased if so desired.
The heat absorption capacity amounts to 23,500 BTU/sec.
Water line connection, 1¼” FPT ball valve.
