Q. How does Draught Guard work?
Draught Guard works by generating and propagating a low frequency AC signal throughout the entire beer line. This sine wave that is induced into the line produces a dense current throughout the inner lining of the beer line, otherwise known as a skin effect. This skin effect inhibits the particulate or organics within the beer from settling out and attaching to the line, reducing and preventing the formation of biofilm and beerstone. Unlike any other system on the market today, Draught Guard's propagating signal is 100% measurable and verifiable.
Q. How many lines does Draught Guard treat?
One Draught Guard unit can treat up to 10 lines, regardless of length.
Q. Is Draught Guard similar to the BLM-2000 or BLM-Q systems?
No, the BLM systems use a completely different technology. They operate using ultrasound as a mechanism of treatment. We are not aware of any testing that proves BLM's sound waves are measurable throughout the trunk line. We also are unaware of any ATP or other industry standard test performed in the United States that proves its efficacy.
Q. Is Draught Guard a magnet?
Draught Guard is not a magnet. Magnets and electromagnets can in fact induce a charge on the beer line, but the charge generated is very small and remains localized at the point of installation. These devices only have a potential of being effective if the beer were to be flowing 24/7. Draught Guard's unique and patented technology, in comparison, propagates a signal throughout the entire length of line – regardless of flow.
Q. Will Draught Guard affect the taste of the beer?
Absolutely not. Draught Guard's technology does not change the chemistry or biologics of the beer. Biofilm and beerstone, on the other hand, are what is responsible for causing off-flavors. Draught Guard's technology inhibits the growth of biofilm and beerstone, assuring both the brewer and dispensing establishment that the beer is being served the way it is intended to be.
Q. How is Draught Guard installed?
Draught Guard is installed in the keg cooler, and can be configured specifically for your set up. Your local Draught Guard representative will ensure the best installation for your system.
Q. How do I know if Draught Guard is working properly?
Unlike all other systems, the Draught Guard signal can be tested, measured and verified. Your local Draught Guard representative can measure and verify the signal using an oscilloscope.
