Our Culture

Our team maintains the highest standard of honesty and integrity. Each of us is empowered with respect. Everything we achieve is a credit to our incredible team.

Exploring Ozone Technology

Advantage Engineering (President: Steve Hengsperger) is prototyping for Dyson Vacuum aka Fantom Technologies. When Fantom is forced into bankruptcy, Mr. Hengsperger hires ex-employees to continue the development of its residential drinking water system using ozone technology. 

Tersano is incorporated and continues with R&D for water treatment systems. Timing is ideal, as the EPA, FDA and USDA all agree that ozone is an approved sanitizer. Tersano introduces a residential sanitizing system for a spray bottle and produce bowl — with great consumer interest. Tersano’s system becomes available in large retail stores and receives the Best Invention award from Time Magazine.

SAO Gets Attention

Tersano introduces Patented Stabilizer Technology, extending sanitizing time to 4 and 24 hours.

Tersano is the first company to achieve Green Seal 37 & 53 approvals simultaneously.

NSF adds ozone to the WhiteList.

International and North American distribution of Tersano SAO grows steadily.

A world leader in Stabilized Aqueous Ozone

Tersano serves clients in various industries such as healthcare, education, manufacturing, hospitality, airports and office buildings. Clients include large facility support services, restaurants, building service contractors — and into homes everywhere.
