Calabrian Corporation
Sulfur dioxide (SO2) is available in a liquefied form, under pressure.
Unlike other manufacturers who produce SO2 using a sulfur burner, Calabrian's proprietary production process generates high purity on-purpose sulfur dioxide by the reaction of pure oxygen with sulfur. This unique closed loop design supports a more efficient and environmentally friendly production process.
