Thorough cleaning without roughening surfaces has always been the challenge – but one company says it has that problem licked. The German company mycon has developed a special configuration of the PowerMaster device for the foundry sector, especially for cleaning core boxes and core hoods. Boasting a cleaning effect equivalent to water pressurized up to 1,200 bar, the PowerMaster cleans plastic surfaces gently, with no abrasion, according to a company press release, getting even encrusted vents working again. The PowerMaster/Mini PowerMaster can be used manually or – for large number of items – automatically using a robot or linear actuator. The operating costs for compressed air, blasting agent and water are around EUR 20-30 per hour, depending on the area output required. 15-30 kg of operating materials are used per hour, depending on the nozzle design. The water-soluble (and food-safe) operating material can be fed into the wastewater pipes directly or filtered. With its JetMaster+ cleaning system, mycon offers a process for cleaning all types of finned heat exchangers. Even the toughest deposits can be removed — for example, from spiral-finned tubes for cooling cupola furnaces, returning them almost to the efficiency of a new exchanger.
