The benefits of this dual pump system are many. Two pumps halve the duty cycle and prolong overall pump life. Furthermore, separate pumps ensure that only fresh, clean water is used, eliminating possible cross-contamination when drain pump residue is reintroduced into subsequent wash and rinse cycles. A washer's cycle time is dependent upon the time it takes for the incoming water to be heated up to wash or rinse temperature. Heater DI Rinse Cycles Complete elimination of residue is best accomplished by one or more heated DI rinse cycles.
Deionized water becomes more aggressive when it is heated, providing better rinsing.
Many glassware washer manufacturers provide DI rinsing capability, but very few provide the ability to heat the DI water to such temperatures. Due to the nature of dental applications, the model G 7781 Dental Thermal Disinfector does not feature a DI rinse. All Miele washers are equipped with a powerful circulation pump. This system provides a high turnover rate of water which provides effective cleaning action in a shorter time period, while remaining gentle on your delicate glassware. Typically, other brands of under-counter models circulate at a less effective rate of 60 to 80 gallons per minute.
