Fixed Beer-Line Cleaning: Qualflow's VerxClean Product Performance With Large UK Pub Operator

VerxClean Benchmarked Against a Traditional Open-Flow Automatic Beer-Line Cleaner

As part of its selection process for a new automatic beer-line cleaner, a major UK pub operator asked Qualflow to benchmark the performance of VerxClean against its current automatic line cleaner. The pub operator wanted a system that would meet the requirements of its new and existing pubs, while reducing the overall cost of ownership. These pubs typically have high tap numbers(>40), bar servers on different levels/floors and split product lines.

The existing equipment install-base implements a tank based, un-pressurised open-flow clean of the beer-lines.

Benchmark Metrics

The pubs were selected for the initial trial. The Verx performance was benchmarked against the old equipment using the following metrics; Efficay of Clean, Keg Yields, Cycle Times, Detergent Usage, Ease of Use, FOB Hygiene

Staff Feedback

In addition to the assessment, management teams at the inital test pubs were asked to complete a survey to compare their experience and assess the performance of the Verx and the old line cleaner. The survey comprised of eight questions focused on the technical features of both line cleaners and the benefits that these deliver. Out of a maximum score of 100, Qualflow's overall performance score was 90%, versus 46% for the old equipment. When asked to assess line clean quality, Qualflow's score is 96%, compared to 48% for the old equipment. When rating their overall opinion of both systems, Qualflow's score is 96% compared to 36% for the open-flow cleaner.


Trial Highlights



Better Clean

Based on ATP line hygiene measurements

Better Clean

Based on ATP line hygiene measurements

Based on ATP line hygiene measurements, the quality of the clean has improved by a factor of 20 since the introduction of Verx. The operator has reported reduced FOBing and improved key yields in addition to better pour quality.



Increased Keg Yields

Keg Yield Increased by 3% to 5%

Increased Keg Yields

Keg Yield Increased by 3% to 5%

Average Keg yields for all products have increased by 4% or 3.52 pints per keg in the trial pubs. This represents the opportunity for revenue yield increase of c£6.5m across the pub estate and a rapid return on investment (< one-year).



Reduced Cycle Time

Cycle Time Reduced by 33%

Reduced Cycle Time

Cycle Time Reduced by 33%

Verx’s high capacity allows cleaning of up to 10 lines per cycle and reduced average cycle times by 33% or 4.3 hours/week in a typical pub. This represents a potential cycle reduction time of c200K hours/year across the pub estate.



Reduced Detergent Usage

Detergent Usage Reduced by 33%

Reduced Detergent Usage

Detergent Usage Reduced by 33%

Verx reduced average detergent usage at the trial pubs by 45%, offering a potential saving of c£900K per annum across all pubs and a significant reduction in the cost of ownership.

The old equipment used excessive detergent to compensate for drain down.



Ease of Use

Score of 90% for Ease of Use

Ease of Use

Score of 90% for Ease of Use

When asked to score the ease of use or level of automation, management teams gave a score of 90% to Verx compared to 44% for the incumbent equipment.



Improved FOB Hygiene

Improved Hygiene Across All Test Pubs

Improved FOB Hygiene

Improved Hygiene Across All Test Pubs

Better process conformance due to Qualflow’s unique FOB Alarm and Smart Hoses, greatly improved FOB hygiene at all test pubs.
