Introducing AURUM ® - LPG Additives with CH25X Technology, the new gold standard for your bottom line.

Compared to propane treated with AURUM ®, untreated LPG emits a higher level of CO emissions and impacts engine wear and performance over time. For your LPG powered equipment, Innospec’s advance AURUM ® LPG additives, with CH25X technology, represent a revolution for autogas, tank cleaning, heating, and metalworking applications.
