Parts and contaminants · 4 min readUltrasonic cleaning in hospital technical servicesCastors, trolley parts, kitchen filters and grilles: what a hospital's technical service can clean in an industrial tank, and the line it must not cross.

Parts and contaminants · 4 min readUltrasonic cleaning of heat exchangers in industryScale, oil, biofilm and deposits on plate packs, tube bundles and coolers cost heat transfer and pumping energy. Which heat exchangers can go into an ultrasonic tank and which cannot, the two-step chemistry for scale and oil, tank sizes for plates and bundles, and the checks before the exchanger goes back into service.

Parts and contaminants · 4 min readUltrasonic cleaning of bearings and mechanical componentsOld grease, wear particles and dirt out of dismounted bearings, gears and couplings so they can be inspected and reused. Which bearings to clean and which never to wash, the settings, and the steps that stop a clean bearing from rusting or being damaged before it is greased again.

Operation and maintenance · 3 min readThe foil test: a one-minute check of cavitationA sheet of household aluminium foil in the bath for sixty seconds shows where the tank cleans and where it does not. How to run it, what the hole pattern means, and how to use it as the acceptance test for a new machine and the monthly check for an old one.

Choosing a machine · 3 min readTank material and wall thicknessOur tanks are AISI 304 stainless steel, 2 mm on the ST and SF series and 2.5 mm from the AL-600 upwards. Why that grade, why those thicknesses, what cavitation does to a tank floor over the years, and when AISI 316 is worth specifying.

Operation and maintenance · 4 min readSafety around an ultrasonic cleaning tankHot alkaline liquid, a running bath that causes pain and tissue damage to a hand put into it, noise above the hearing range that is still noise, fumes, and heavy baskets over an open tank. The hazards of an industrial cleaner, and the habits and fittings that control them.

Industries · 3 min readUltrasonic cleaning in heavy industry: energy, oil and gas, mining, railHeat exchangers, valves, pump and compressor parts, turbine components, hydraulic blocks and filters from plants where a stopped machine costs more per hour than the cleaning tank costs to buy. Large tanks, heavy baskets, scale and heavy oil, and the maintenance schedules they fit into.

Process and parameters · 4 min readFiltration and bath lifeA cleaning bath fails in three ways: it fills with particles, it saturates with oil, or its chemistry is used up. Filtration handles the first two and stretches the third. What a filtration loop and an oil skimmer do, when a bath needs them, and how to tell when a bath is finished.

Operation and maintenance · 4 min readEnergy and running costs of an ultrasonic cleaning tankThe heater, not the ultrasound, is the cost. What a 96-litre and a 300-litre tank draw over a shift, where the kilowatt-hours go, and the four habits that cut the bill by a third: lid, timed heat-up, the right temperature, and a bath that lasts.

Operation and maintenance · 3 min readDaily and weekly maintenance of an ultrasonic cleanerAn ultrasonic tank has no wear parts in the liquid, so maintenance is about the bath, the floor, the filter and the heater. A routine that takes ten minutes a day and half an hour a week, and what to look at once a month.
