How ColdFog® Works

Understand a Cold Fog ^® System

A Cold Fog^® system is a completely self-contained system capable of generating man-made water fog for humidification, cooling, special effects and other applications.

The Cold Fog^® 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 Cold Fog^® system is shown below.

We offer the world’s only PATENTED ruby-orifice fog nozzles with 9 kinds of diameters:

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:

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 Cold Fog ^® 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.
