AMS Spectral UV unveils LED UV, IR drying innovations that save energy, speed production, including LED UV Quatro Series System that emits more than twice the output of traditional lamp heads at two different frequencies, uses less energy

June 10, 2022 (press release) –

It's really good to be back exhibiting again after all this time. And we can actually show the marketplace the things that we've actually been working on to try and improve the situation.

Two challenges both to do with UV curing and drying. 1: The machines are getting faster, faster, so the LED UV system gets more powerful and there's actually less space on a lot of machines for an LED system. 2: When it comes to customers who print with conventional inks and water based coatings, they would like to have something like energy reduction, because it's amazing the amount of energy that's consumed by existing IR, hot air, and drying systems that have been used in the past.

On the LED UV side, what we've launched now, and what we brought out is our new LED UV Quatro Series System. This is an extremely compact LED lamp head that has more than twice the output of traditional lamp heads that we have been supplying. And we have situations today where the LED UV system will never, ever limit speed of your machine or cause a curing issue. Another unique feature of this particular technology, the Quatro, is the fact that we can have two different frequencies of LED light. We have 405 nanometers for deep cure and 365 nanometers for surface cure, so that you actually get the perfect cure as well as having extremely high speed applications.

The other unique thing here, you only need one head. We don't need to have several lamp heads to compensate for inefficiency of lamp heads or something like this. So, it's one unit giving you all the benefits of LED, which is actually extremely low energy consumption as well.

I mentioned earlier that one of the challenges today is the cost of energy in the printing world. And also, machines are getting faster and faster. So we went away and we developed a brand new IR hot air system. Here you can see in our unit we have these special IR lamps. They're patented lamps. They've got a very, very special ceramic jacket around the outside of the lamp that collects all of the IR and directs right down onto the substrate.

This stops all of the waste that happens with traditional IR systems going back and deflecting it back on the lamp and getting lost. So all of our simulations, we expected to see energy consumption reduction of about 30%, but on our first installs, we've actually seen reductions of about 40%.

Now, when you think about the fact that typically sheet-fed press consumes maybe 80, 85 kilowatts of IR hot air, a 40% reduction in that is dramatic. The same on some high speed web applications where IR airs being used, it might be consuming 200 kilowatts, for example. A reduction of 40 kilowatts is dramatic there as well. And also we have, as you can see, the unit is extremely compact. It's lightweight. And with this type of technology with the lamps arranged this way, if you're printing on a narrow substrate, we can actually turn off the lamps on the outside too. Also reduces the energy consumption. These are two of the things that we're doing to try and improve the situation.
