NEW Guyson International Kerry Microsolve M250 Ultrasonic Precision Solvent Cleaning Line

Cleaning with or without the use of ultrasonics is carried out in the stage one tank by immersion of the components into the solvent. The ultrasonic transducers are mounted on the tank base and powered by the Guyson Primewave dual frequency generator incorporating
ultrasonic output power control, pulsed operation of the ultrasonics (if required) and frequency modulation and sideband sweep. Stage one is also supplied with solution heating and a pumped closed-loop filtration system comprising a course strainer, fine filter cartridge,
welded pipework and “O” ring sealed valves.

The second tank (stage two), is electrically heated with unique pulsed control operation allowing the solvent to boil efficiently whilst helping to minimise solvent emissions.
The resulting vapour rinses the components, which are then dried in the freeboard zone (stage three). Distilled solvent, condensed by the primary cooling coils, passes through a water separator with in-line heat exchanger and returns to the ultrasonic tank, displacing contaminated solvent into the boiling sump. Distillation, together with filtration of the solvent, ensures that the ultrasonic tank is maintained at a controlled level of cleanliness.

Solvent retention features unique to the Microsolve range include triple coil reflux cooling, vapour break, 150% freeboard, optional auto top-up and solvent monitoring. These ensure that systems are safe and comply fully with environmental and safety legislation. These design features also mean that Microsolve systems are able to operate with low, predictable solvent
usage and customers enjoy low, predictable running costs.

The Mono-Solvent process is intended for applications with light to medium contamination levels and typical applications include precision cleaning of bearings, gyro components and medical components; maintenance cleaning of pneumatic and hydraulic components; and, in electronics, rosin flux removal from PCBs or from solder jigs and fixtures.
