High-Temperature Sanitization on Warewashing Machines — NSF/ANSI 3 Explained
High-temperature sanitization disinfects cookware with heat alone: a fresh-water final rinse at 82–85 °C thermally kills bacteria without chemical sanitizer. This is the thermal-disinfection method described in NSF/ANSI 3 for commercial warewashing machines.
Thermal vs chemical sanitizing
Warewashers sanitize one of two ways: a hot final rinse (thermal) or a chemical sanitizer dosed into a lower-temperature rinse. Thermal needs no consumable chemical and leaves no residue, but requires a booster heater to reach rinse temperature reliably.
The temperature threshold
For thermal sanitizing, the rinse water reaching the ware must hit the sanitizing band. The CE-UWL delivers an 85 °C rinse via a 15 kW booster heater, comfortably inside that band.
What NSF/ANSI 3 covers
NSF/ANSI 3 is the standard for commercial warewashing equipment; it defines the temperatures and conditions under which a machine is considered to sanitize. Confirm any project-specific NSF listing requirement with your sales contact, as listing is separate from meeting the temperature method.
- Thermal sanitizing uses heat, not chemicals.
- The CE-UWL rinses at 85 °C via a 15 kW booster.
