The E888R — Recessed Ultrasonic Cleaner incorporates high powered ultrasonic technology with a sleek, flush-mounted recessed designed. The unit is designed to aid in the presterilization preparation process for instrument reprocessing. With a large 3/4” solenoid drain valve, the E888R provides auto-draining, as well as auto-filling for convenient changing of ultrasonic detergent. Changing out solution is as simple as flipping a switch. A 200 watt tank heater maintains solution temperature at 110°F allowing for maximum ultrasonic cavitation. Solid state circuitry supplies AC voltage to transducers with a continuous, complete square wave at a constant amplitude. This produces multiple harmonics to the bath . This circuitry tends to fill the less active areas in the bath providing more homogenous cleaning. The automatic tuning circuit adjusts the primary resonant frequency of 38 Khz for changes in loads and liquid levels. The combined effect of this superior circuitry is to produce a unit that is “not just another ultrasonic”. These counter-recessed, flush-mounted units require very little counter space and need no more installation than a sink, and they really perform! Controls are conveniently located on the top-plate for ease of operation.
