Cleaning method in critical process environments
The NHK High-Frequency Impactor cleans heat exchangers efficiently, removes deposits, boosts efficiency, extends uptime, and reduces costs.
NHK High-Frequency Impactor – Maximum Efficiency for Heat Exchangers
Heat exchangers are the heart of industrial processes. Deposits of dust, flue gases, or chemical particles can reduce their performance. The NHK High-Frequency Impactor from NetterVibration effectively removes even stubborn buildup, ensuring continuous cleaning, boosting energy efficiency, extending operational uptime, and significantly reducing maintenance costs.
Innovative Technology for Superior Cleaning
The NHK operates with a freely oscillating, self-adjusting piston that drives a heavy mass to strike the surface up to 50 times per second. Unlike conventional devices, it delivers many light impacts instead of single strong blows, thoroughly cleaning surfaces while protecting the equipment. The striking frequency is infinitely adjustable, and depending on pressure, the NHK can either vibrate or strike, delivering optimal cleaning results for every application.
Robust and Flexible – Designed for Heat Exchangers
Built for demanding environments, the NHK is heat- and corrosion-resistant, making it ideal for critical locations such as tube bundle or plate heat exchangers. Deposits are removed during operation, minimizing downtime and extending equipment life. Placement and calibration are performed on-site by NetterVibration experts to ensure maximum efficiency.
Proven in Industrial Applications
In waste-to-energy or biomass plants, the NHK keeps heat exchanger surfaces free from flue gases, dust, and lime buildup. Tubes are vibrated at high frequency and, if needed, struck, ensuring continuous heat transfer and maintaining energy efficiency.
Versatile Applications
Beyond heat exchangers, the NHK is used in foundries and industrial production processes: under vibrating tables to compact molding sand, for removing sintered metal parts, in permanent mold casting, and for compacting stampable furnace masses. Its combination of vibration and impact makes it a powerful and flexible tool for a wide range of applications.
