No, the RapidHeat Sterilizer involves only rapidly moving hot, dry air to sterilize instruments. As such, the only moving mechanical parts of the sterilizer are (1) the blower (fan and motor) for moving hot, dry air over a heating element, repeatedly through the sterilization chamber and (2) the cooling fan to maintain temperature control for the printed circuit boards and outer sterilizer housing. There is no vacuum system nor does the unit require water or a drying system. The sterilizer is pre-set for thermocouple-controlled temperature and sterilization cycle times. The unit requires little or no maintenance as compared to the more complicated steam sterilizer technology, which requires frequent cleaning and maintenance of all the mechanisms involving the management of steam, water, pressure, and vacuum.
