Cases Overviewnu glass Partners With KNF To Create Revolutionary Frequency Transparent Windows
The Swiss startup, known for its process that makes glass permeable to telecommunication frequencies, works closely with KNF to create their revolutionary technology.
The world is becoming increasingly more reliant on wireless technology in both professional and personal applications. Even as this technology evolves, wireless users continue to face certain unique challenges. Making calls or using data indoors can still be a hassle in many locations. This is especially true for those using public transportation like trains, where window glass greatly impacts wireless signals. Swiss startup nu glass has created a revolutionary new technology to solve this problem. Their cutting-edge process relies on KNF diaphragm pumps.
Wireless Signals Have Difficulty Penetrating Glass
While wireless signals have become stronger and more efficient in recent years, they still struggle to penetrate building materials, including insulating glass. This makes it difficult, and in some cases impossible, to get service indoors. Everyday clear glass can reduce wireless signal by up to 4 decibels (dB), while coated glass can reduce signal by as many as 30 dB (x1000). This is especially a problem in public transportation vehicles like trains, where passengers may struggle to receive wireless signals at all. It is an issue faced by commuters worldwide, for which Swiss startup nu glass has developed a cutting-edge solution.
A Unique Glass Cutting Pattern Drives Improved Signal
Most glass is insulated with a thin metal layer invisible to the naked eye. nu glass uses a patented laser technology to engrave a pattern on this layer, allowing for wireless frequencies to penetrate the glass. This treatment can increase indoor signal by up to 1000 times. The etching is nearly invisible, and it has no detrimental impact on the glass and keeps its original protective properties. It allows for penetration by all commonly used wireless frequency ranges.
nu glass uses a portable system to complete the engraving process, allowing them to visit customers on site. The system can engrave glass while it’s in place, preventing the costly and time-consuming process of removing and reinstalling individual panes of glass. The process is fast and efficient and can be applied parallel to standard maintenance, allowing for trains to keep on their schedule and return to service on time with enhanced connectivity.
“At nu glass we work to deliver the best connectivity no matter where they are, within an efficient and passive solution” Luc Burnier, Founder and CEO of nu glass, said. “Our revolutionary technology invented at Switzerland EPFL makes it possible on existing and installed glazing.”
nu glass’s revolutionary glass cutting pattern allows wireless signals to better penetrate windows. The engraving can be completed on-site without having to remove windows.
KNF Pumps Facilitate Etching Process
KNF diaphragm pumps play an integral role in nu glass’s cutting process. The system uses multiple N 838 pumps, which provide the necessary suction. Pumps are used in suction plates, which help adhere the system to the window during the engraving process. nu glass’s system is currently used exclusively on trains but could potentially be used on glass installed in buildings or other structures.
The N 838 is an outstanding gas transfer pump option. It offers a maximum flow rate of 34 l/min with an ultimate vacuum down to 100 mbar (abs.). Also available are a variety of motor options, including brushless DC motors. The N 838 has excellent reliability and operates oil free, preventing media contamination.
KNF’s N 838 diaphragm gas pump plays a vital role in nu glass’ engraving system, holding it in place during etching.
KNF Provides More Than Just Pumps
While finding the ideal pump for their system was important, nu glass wanted to make sure they were working with a partner that shared their values. A focus on quality and sustainability are the key components of those values. It was also important for nu glass, which began its life at the EPFL Lausanne, to work with a local company. This made working with KNF, with multiple facilities in nearby cities and a strong presence in the community, a natural choice.
“While we needed to find a pump that met our needs, it was important to find a business partner that we could grow and work closely with as well,” Burnier said. “KNF provided both of those for us.”
KNF has locations in 24 countries and more than 900 employees worldwide, a commitment to collaborative pump design allows each location to serve their communities directly. KNF engineers work closely with customers to specifically tailor pump solutions to their needs. This dedication to local partnerships coupled with the backing of a large global team allow KNF to provide a high level of service for a wide range of customers.
