The VariMach sonic flare tip features spring-actuated variable sonic nozzles to allow the exit area to vary with pressure, ensuring constant sonic velocity of the exiting waste gas. This industry proven technology guarantees sufficient inspiration of air to ensure 100% smokeless combustion and infinite turndown. Radiation levels are also minimized throughout the entire range of flow, yielding shorter stack heights and reducing material costs. Additionally, the VariMach has the lowest purge rate of any flare technology on the market, minimizing utility costs while maintaining flashback protection.
