Change of personnel at LPW

Björn Lepple new Service Manager

At the turn of the year, LPW Cleaning Systems GmbH experienced a personnel change. Service Manager Markus Hoch has left the Ried-based company to accept a CEO position. He has been succeeded by Björn Lepple.

LPW CEO Gerhard Koblenzer: "We thank Mr. Hoch for the years together and wish him all the best…

Changed cleanliness requirements in type and quantity require different testing methods. In addition to technically complex and time-consuming procedures (e.g., XPS, ATR/FTIR, TOF-SIMS, etc.), UV light inspection has proven to be a quick method that makes even the smallest particles or fibers visible.

Nothing enters the cleanroom without pre-cleaning to avoid any contamination. (Photo/Graphic: LPW)

The LPW pure water supply unit for the final rinses in the TDZ represents another important component in ensuring process quality. (Photo/Graphic: LPW)

The quality of the cleanroom air concerning particulate contamination and turnover frequency is maintained in a recirculation filter system and controlled via process data monitoring (including particle counters). (Photo/Graphic: LPW)

The cleaning system can contribute to recontamination, not only during the cleaning process itself, but also through unintended cross-contamination of the product. The maintenance area is also often a source of this and is therefore always placed outside the cleanroom in LPW systems. (Photo/Graphic: LPW)

Industrial cleaning technology in high purity environments

A cleanroom alone does not ensure cleanliness

When it comes to industrial cleaning technology, applications in or before cleanrooms are increasingly being discussed — and not only in the medical and semiconductor segments. However, there is sometimes the impression that simply combining a cleaning system with a cleanroom provides the solution…

The new cleanroom has been significantly improved in its range of performance regarding monitoring, energy efficiency, and performance. (Photo: LPW)

After the fire: modern, powerful, and absolutely high-tech.

LPW Test and Service Center reopens

After just under six months of construction, the test and service center for precision cleaning at LPW's company location in Riederich was recently reopened. Due to a fire at the beginning of the year, it had to be rebuilt from scratch. The cleaning specialists took this as an opportunity to make th…

The PowerJet Compact CNp system (from left to right: Clean module, Clean AM, and Pure) is standardly equipped with an integrated treatment chamber embedded in the two feed tanks for goods up to a batch size of 600 x 400 x 300 mm for weights up to 150 kg. The recirculation system features an integrated full-flow filtration with a filter area of over 4 m² and filter units down to 0.5 μm.

Increase for PowerJet Compact CNp system family

Highest purity after additive manufacturing

In nearly all areas of the High Purity industry, 3D-printed components are now in use. Due to their special shapes and complex internal geometries, they require special treatment during post-processing. Therefore, LPW Reinigungssysteme GmbH has expanded its PowerJet Compact CNp system family with th…

After fire at the LPW Test and Service Center

Operations continue as usual

Last Thursday, a local fire with heavy smoke development occurred in the building of the Test and Service Center (TDZ) on the premises of LPW Reinigungssysteme GmbH in Riederich. The cause was probably a technical defect in a water treatment system. Fortunately, no one was injured. The extent of the…

The CNp Technology: A Game-Changer in High Purity Processes: Last year, LPW obtained the European patents for the CNp process (Cyclic Nucleation), which has been in use and internally developed for years, following international rights. CNp acts directly on the boundary layer of a component, even in hard-to-reach internal contours (such as 3D implants or fine capillaries and lumens). Through targeted pressure fluctuations within the liquid-specific vapor pressure curve, the formation of vapor bubbles, the cleaning effects of gentle cavitation, and effective media exchange, contaminants are dissolved and, if necessary, residual contamination carried along is safely removed. With the ultrasound-CNp combination as a process enhancer, LPW also tackles the most challenging tasks in fields such as medical technology or high vacuum technology.

New CNp System: Small Powerhouse for Highest High Purity
New to the LPW portfolio is the space-saving standard chamber system PowerJet compact CNp. The two-stage system with integrated steam intermediate rinse occupies just under 4 m² and features, in addition to ultrasonic and Cyclic Nucleation (CNp) cleaning processes, the necessary drying for higher requirements. This can be implemented in the form of hot air as well as infrared vacuum drying. Furthermore, the new system is equipped with a treatment chamber embedded within the two pre-treatment tanks, suitable for goods up to a batch size of 600 x 400 x 300 mm and weights up to 150 kg. The sandwich construction supports cleaning and rinsing processes as well as drying through a higher temperature level. The recirculation system features integrated full-flow filtration with a filter area of over 4 m² and filter units up to 0.5 µm. Currently, the small powerhouse is available in two versions.

1. New products in medical technology, such as additively manufactured implants, pose new challenges for cleaning equipment manufacturers. Additionally, there are regulatory requirements (in Europe, the Medical Device Regulation) that must be addressed. (Photo: LPW)

2. Capillary structures, such as in fine channels and tubes, are subject to the highest cleanliness standards depending on their intended use. Due to their aspect ratio (the ratio of inner diameter to length), these components make the use of most known cleaning methods impossible and also challenge the rinsing and drying processes. Here is a 300 mm long glass capillary with an inner diameter of approximately 50 µm. (Photo: LPW)

3. In laser and high vacuum technology, cleaning is confronted with delicate and highly precise processed surfaces – such as mirrors, for example. (Photo: LPW)

4. The influences of drying on the degree of technical cleanliness are often underestimated. For example, energy-efficient recirculating air drying tends to concentrate the finest organic and inorganic contaminants, which can lead to recontamination of the components. Therefore, LPW uses environment-decoupled infrared systems. (Photo: LPW)
