Understand a ColdFog® System
A ColdFog® system is a completely self-contained system capable of generating man-made water fog for humidification, cooling, special effects and other applications.
The ColdFog®fog system is complete with pump, motor, water filters, control panel, nozzles, tubing, operating manual and water treatment package. Working pressure is 400-3200 psi (adjustable). A typical ColdFog® system is shown below.
We offer the world’s only PATENTED ruby-orifice fog nozzles with 9 kinds of diameters:
| Flow Rate
at 1000 psi
|ASI-4R||0.0040″||0.11 mm||0.014 gpm|
|ASI-45R||0.0045″||0.11 mm||0.017 gpm|
|ASI-5R||0.0050″||0.13 mm||0.020 gpm|
|ASI-55R||0.0055″||0.14 mm||0.025 gpm|
|ASI-6R*||0.0060″||0.15 mm||0.026 gpm|
|ASI-8R||0.0080″||0.20 mm||0.046 gpm|
|ASI-10R||0.0100″||0.25 mm||0.072 gpm|
|ASI-12R||0.0120″||0.30 mm||0.092 gpm|
|ASI-15R||0.0150″||0.38 mm||0.120 gpm|
*standard nozzle orifice size:
0.006″(.15mm). gpm = gallon per minute.
The nozzle consists of a 316 stainless steel body with ruby-orifice, 316SS impingement pin and extended polypropylene filter to avoid trapping particles in the base of the nozzle. High-pressure water (400-3200 psi) reaches the nozzle, shooting a fine liquid jet against an impingement pin of equal diameter resulting in the finest atomization possible, atomizing water into billions of 1 to 15 micron droplets like those occurring in natural fog.
Ruby-orifice nozzle spray shown below:
The degree of atomization (the size of water droplets) produced by a nozzle can be divided into the ranges shown below, comparing with known droplet diameters for different types of precipitation:
|Type of Precipitation||Size of Droplet (Microns)|
|Note: 1 = 25,400 Microns (µm)|
Using our patented ruby-orifice nozzle, you now get precise flows and predictable fog for your applications. Droplet analysis sheets will be supplied upon request. ASI-6R nozzle droplet analysis shown below,
Why Does the ColdFog® Ruby-Orifice Nozzle Have Such a Long Life?
Brass or ordinary stainless steel orifice nozzles have a relative life, since the passage of water under high pressure will enlarge the orifice in a short period of use. Nozzle wear is characterized by an increase in nozzle flow, followed by a general deterioration of the spray pattern, increased droplet size and loss of system efficiency. ASI ruby-orifice nozzles have Lifetime Unconditional Orifice-Wear Warranty.
|Steel||1.5 to 2|
|Monel||2 to 3|
|Stainless Steel||4 to 6|
|Hardened Stainless Steel||10 to 15|
