Beer waste is often significantly underestimated. For reference, a standard 3/8" beer line holds approximately 0.75 oz per foot. With a typical bi-weekly cleaning schedule, the amount of beer flushed down the drain adds up quickly.

Example:

A 12-product Century system with 80 ft lines, cleaned bi-weekly, will discard approximately 18,720 oz of beer per year.

That same system protected by Draught Guard and cleaned quarterly will discard only 2,880 oz annually—an 85% reduction in beer waste.

Only a small number of states have strict language governing beer line cleaning frequency. Draught Guard has received approval in several of those states, including Connecticut and Pennsylvania.

While every draught system is different, the average return on investment for Draught Guard is well under one year. ROI is influenced by multiple factors, including line count, line length, keg costs, cleaning costs, CO₂ usage, and beer waste reduction.

The main enclosure features an LCD screen that confirms normal operation. During startup, the system displays the treatment signal, verifying that Draught Guard is actively transmitting its signal throughout the beer lines.

Over five years of lab and field testing—conducted with major breweries, quality experts, and industry partners—Draught Guard has been shown to outperform traditional two-week caustic cleaning in controlling biological growth.

Independent lab results demonstrate that Draught Guard inhibits up to 98% of sessile bacteria (biofilm). Unlike caustic chemicals, Draught Guard also actively breaks down and removes existing biofilm. On average, biological levels at the end of Draught Guard’s 12-week cycle are lower than those measured after a standard two-week caustic cycle.

No. Draught Guard is not ultrasonic. It operates using electromagnetic radio frequencies, transmitting its treatment signal through the beer itself via conductivity.

Ultrasonic sound waves dissipate rapidly and have not been proven effective at inhibiting, killing, or removing biofilm in beer lines.

See the response above regarding ultrasonic technology for key technical differences. Additionally, Draught Guard has been rigorously tested and validated through dozens of field pilots and university studies, demonstrating proven effectiveness against both mineral and biological buildup. Draught Guard only makes claims supported by published data—data that competing technologies have yet to provide.

Draught Guard is non-invasive and can treat up to 12 lines per unit, while FlowMaster’s magnetic technology is invasive, requires plumbing modifications, and treats only one line per device.

Draught Guard provides continuous, system-wide protection regardless of flow or line length, operating 24/7. Magnetic technologies treat only at the point of installation, require consistent flow, and have not been independently validated for biological control.

No. Ongoing sensory evaluations conducted by industry quality experts confirm that Draught Guard has no impact on beer flavor or aroma.

Additional blind taste testing at AB-Technical College found Draught Guard–protected lines produced results consistent with standard two-week caustic cleaning.

For nearly two years, the sensory team at Leinenkugel’s Brewery has conducted monthly evaluations on 48 Draught Guard–protected lines, all meeting their quality standards.

No. While Draught Guard is third-party validated to extend cleaning intervals, it does not fully replace line cleaning. A complete caustic and acid flush is recommended every 12 weeks. Faucets and couplers should continue on a bi-weekly cleaning schedule.

No. Faucets and couplers must remain on their standard bi-weekly cleaning cycle. FOBs should continue to be cleaned on the standard quarterly (12-week) schedule.

This is a common concern, but the opposite is typically true. Draught Guard increases operational efficiency by maintaining line cleanliness between visits, allowing technicians to focus on faucets and couplers during bi-weekly service. This efficiency enables line cleaners to take on more accounts, scale their business, and improve overall profitability.

None. A simple visual check of the LCD screen during routine service visits is recommended to confirm normal operation.
