In 1990 DeLille Oxygen Company started their own Specialty Gas division which was rare for an independent distributor at the time. Since then DeLille has continued to expand their offerings in the specialty gas division to suit any industry’s needs not only in terms of lead time, but in quality as well. DeLille became a certified supplier for Purity Plus in 2008 in order to have third-party certifications and standards that are even higher than traditional standards.
