Yes, in high pressure leak detection.
Some of our designs are for industrial applications which require them to produce smoke at very high pressures (some as high as 120 PSI or more). An inert gas, such as nitrogen, must be used with those high pressure machines because the oxygen in shop air will cause a ‘flash’ effect inside the smoke machine chamber.
One of STAR’s patents is for exactly that application. All smoke machines manufactured today, when used with shop air, will flash if enough pressure is created inside the smoke chamber (flash can start to occur between 20-40 PSI / 1.4-2.8 bar). Our inert gas technology allows us to manufacture smoke machines for any pressure setting while completely eliminating the flashing issue.
