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.

One Draught Guard unit can treat up to 12 lines, regardless of length.

No, the BLM systems used a completely different technology. They operated 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, nor are we aware of any ATP or other industry standard test that proves its efficacy in maintaining line cleanliness, or preventing the growth of biofilm or beerstone.

Absolutely not. Draught Guard's technology does not change the chemistry or biologics of the beer itself. 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.

Draught Guard is installed through a simple, non-invasive process. Mounted inside, outside or near the keg cooler, the units can be configured specifically for your draught system and setup. Your local Draught Guard representative will ensure the best installation for your system, testing for full signal strength and propagation.

After your local Draught Guard representative installs the equipment, they will test and ensure signal strength and propagation. Unlike other systems, the Draught Guard signal can be tested, measured and verified using an oscilloscope, and ongoing signal monitoring will be displayed on the system's LCD screen.
