What is the difference between Medium Pressure and Low Pressure UV Lamps?

There are many factors to consider when looking into what type of UV treatment system to implement into your production process. To ensure you are selecting the right equipment for your goals, it is important to understand the difference between Medium Pressure and Low Pressure Lamps.

So what is the difference between these two types of lamps?

Low Pressure UV Lamps produce a single monochromatic wave length of 254 nanometers. Medium Pressure lamps are polychromatic, producing multiple types of wave lengths between 200 and 400 nanometers.

What are the advantages and disadvantages of Low Pressure UV Lamps?

The single wave length that Low Pressure lamps produce is right within the germicidal range of 250 to 280 nanometers which makes them more efficient. While Low Pressure lamps are more efficient than Medium Pressure, they are less powerful so you need more lamps in order to reach the right level of disinfection. Low Pressure lamps also typically have a longer lamp life.

What are the advantages and disadvantages of Medium Pressure UV Lamps?

Medium Pressure lamps are much more powerful than low pressure lamps so you need a smaller number of lamps. This allows you to be able to treat relatively high flow rates with less lamps. While these lamps are more powerful, they are less efficient and have a shorter lamp life when compared to low pressure lamps.
