Company History

  1. 1955

    Founded

    Started as a family shop building carbon and stainless-steel storage tanks for the chemical and carpet industries, earning a reputation for tight tolerances and reliable welds.

  2. 1988

    Entering Pharma

    Began fabricating tanks for Eli Lilly, adopting GMP-ready practices, sanitary finishes, and documentation standards that set the foundation for pharmaceutical equipment work.

  3. 1990

    First Chromatography Prototype

    Built our first prototype chromatography column in 316L stainless steel with sanitary connections and precision flow distribution—designed for pilot-scale bioprocessing and easy CIP/SIP.

  4. 1993

    First Patent Awarded

    Secured our first patent for chromatography column design, improving flow uniformity and turnaround time. This milestone accelerated our shift into large-scale pharmaceutical separation systems.
