There are two common forms of sanitizing systems for dishwashers: High Temperature Sanitizing and Chemical Sanitizing. The Differences?
High Temperature Sanitizing Machines
High temperatures sanitizing dishwashing machines use heat to sanitize dishes and glassware. These machines require a booster heater to raise the temperature of the final rinse to 180°. Some machines require the separate purchase of a booster heater.
Unlike the Low Temperature Chemical Sanitizing machines, these do not require regular purchasing of chemicals, however, they typically use slightly more energy than a chemical sanitizing machine.
Chemical Sanitizing (Low Temperature) Machines
These machines use a chemical bath to sanitize dishes and glassware, thus requiring a monthly purchase of chemicals. However, these machines reduce water heating energy costs.
They are usually less effective when washing grease-laden wares as opposed to high temperature units, and dishes may not dry as effectively if humidity in the dish room is too high.
