The Axis Universal Safety Scrubber helps to protect analyzers from corrosion due to acidic gas stream components, especially Sulphur Trioxide, Hydrochloric Acid, Sulphuric Acid & Hydrofluoric Acid. The Universal safety scrubber ( USS1 ) can be used in lime-fired boilers, coal-fired boilers, waste incinerators, and many other applications, where SO3, HF, and HCL in certain limits are present. This can also be installed after the cooler which ensures no carryover of acid and increase the life of the downstream components, especially the sample cell. USS1 material condition should be checked to ensure the right result of acid removal. Life depends on factors like the presence of aggressive components, flow rate, and period till the sample passes through the USS1.
