Use cases of UV lamp drivers
The quality of UV lamp drivers is so important because of the critical nature of UV applications for various use cases. These include water treatment, air and surface disinfection, and UV curing.
UV light can be used to treat water by attacking the genetic material of any bacteria and virus present. By focusing on quality and efficiency, intelligent UV lamp drivers can be used with minimum environmental impact in various applications. UV and advanced oxidation technology are very suitable if you want to develop a sustainable water treatment solution.
Air and surface disinfection:
Due to UV’s anti-microbial properties, it can also be used to disinfect surfaces and inactivate airborne pathogens. UV disinfection is deployed in a wide range of applications and industries and is particularly useful in high-contact areas. UV light reliably reduces the germ load and improves hygiene and storage conditions. UV lamp drivers can be used to adjust UV output so you achieve your desired disinfection level.
High-intensity UV light can also be used in a photochemical process that instantly cures inks, coatings, or adhesives. Not only is this fast, but it is also more practical as it reduces logistical complexity and no harmful solvents are released.
There are two groups of drivers that are used depending on the specific type of UV project: Low-Pressure UV Lamps and Medium Pressure UV Lamps.
Low-pressure lamps, limited to 1000 W, provide exactly the right wavelength of light to fight bacteria and have several advantages compared with medium-pressure lamps. The conversion rate from electrical to UV energy for low-pressure lamps stands at around 34 to 38percent. This means they deliver a higher rate of efficiency than medium-pressure UV lamp drivers, where the conversion is around 12 percent.
While the higher efficiency level of low-pressure lamps may be advantageous in certain circumstances, medium-pressure lamps can achieve higher levels of electrical power - as high as 36 kW. As such, medium pressure lamp drivers are likely to be more suitable for projects that have limited space and need a high UV level, as in some space-restricted water disinfection systems.
Medium-pressure lamp drivers also produce light of multiple wavelengths, which is beneficial for advanced oxidation. Besides attacking the DNA of bacteria, they can also be combined with other solutions to help with the breakdown of chemical substances.
What are the advantages of Nedap UV driver technology for your business?
The efficiency of UV lamp drivers is crucial for several reasons. Firstly, poor quality lamp drivers can result in damage to the UV lamp from over-voltage or component stress. Before the advent of electronic lamp drivers, many businesses relied on electromagnetic devices, which were inefficient, offered less control in terms of power, and required extra attention in terms of their mounting and space requirements.
At Nedap, we are proud of the efficiency and power output levels we are able to achieve with ourUV lamp drivers. We advise you to select UV sources with higher levels of energy efficiency, lowering costs for your customers business over the life time of a product, reducing carbon footprint, and improving your product reliability. Initial low-cost lamp driver systems offering limited features with regard to the power factor, THD, and efficiency will lead to higher operational costs during the lifetime of your UV systems.
Nedap’s driver technology is already employed to improve the safety of drinking water and optimize the printing process for millions of customers around the world. Our UV lamp drivers have already been put to use in several world-leading projects. In New YorkCity, Nedap supplied the lamp drivers for one of the largest UV drinking water purification plants ever built. The plant can supply 8.3 billion liters of clean water to more than 9 million inhabitants in New York and its surrounding areas. The plant uses more than 6000 Nedap UV lamp drivers to purify the water, offering engineers full monitoring to test the UV lamp settings at anytime using dedicated Nedap software.
Elsewhere, one of the leading US printing companies was able to reduce its energy usage, lower installation costs, and cut space by approximately 50% by switching from electromagnetic 50/60 Hz ballasts to our high-frequency electronic lamp drivers. The benefits of the reliability, high levels of efficiency, and high PowerFactor offered by our technology, in combination with step-less dimming, were the major factors that prompted the decision to adopt Nedap’s solutions.
