The TURI Lab recently completed an evaluation on the life span of the ozone in a Series 1. Tersano Series 1 is reported to stabilize sanitation time for up to four hours, operating time for up to 3 days, and have a filter cartridge life of 1,600 gallons. It claims to replace all all-purpose cleaners, stainless steel cleaners, glass cleaners, neutral cleaners, and deodorizers.
Initial weights of stainless-steel coupons were recorded and then coated with 0.5 grams of DCC-17 soil. The coupons air dried overnight and dirty weights were recorded the next day. A clean 5-gallon bucket was filled to the 4-gallon marker 3 times with the ozone water. In a clean 1000ml glass beaker, ozone was collected to the 800ml marker. Three dirty coupons were placed on the abrasion machine at a time per abrasion trial. Using a spray nossil, the ozone water was sprayed once on each dirty coupon and then once on a wypal towel. The machine was run for 20 cycles (30 seconds of cleaning), and then the clean coupons were removed to air dry overnight on a tray. This process was repeated for the 30min, 60min, 120min, and 240min mark for Series 1 with the same sample of ozone water per trial. Clean weights were recorded for percentage removal the next day.
DCC-17-33% vegetable shortening; 33% lard; 33% vegetable oil; 1% carbon lampblack.
