Beer Line Cleaning…

Nobody enjoys cleaning beer lines – it’s a chore, it’s expensive and it involves throwing away perfectly good beer.

StayClean have been helping pubs, clubs and bars to reduce their costs and increase their profits for more than 25 years.

With a StayClean system installed you can reduce line cleaning frequency and make some significant savings*.

Most importantly: the beer you serve will taste just as fresh as it always has.

Happy customers and increased profit on every barrel means everyone wins. That’s the StayClean Advantage.

Typical Savings

*an average bar with eight lines, each containing three pints of beer can expect to save approximately £3,000 per year by reducing line cleans from weekly to monthly.
Try our calculator to see how much you could save.

  • StayClean does not affect taste, as it never comes in to direct contact with the beer.
  • The system is installed without making any changes to your existing cellar – our equipment fits around your current cellar set-up, complies with insurance requirements and is approved for use by breweries.
  • Running costs are as low as £30 per unit per year – less than £10 per line.
  • When you do need to clean your lines you simply follow your standard process
  • All StayClean installations are backed by our 5 year guarantee covering parts and labour.
  • You start saving from day one.

How it works

StayClean beer line cleaning systems use digital technology and high quality antenna cables to develop a lossless ultrasonic signal that gently pulses the beer in the lines.

This action slows the build-up of yeast clumps and bio-films that tarnish the beer in the lines.

Our system has been tested and proven by the Department of Sonochemistry at Coventry University, by Professor Mason and his team.

Cellar Temperature Monitoring

SC Four features an on-board sensor for cellar temperature monitoring.

Cellar temperature is a key factor in maintaining beer quality. If your beer is getting warm in the cellar your lines will need cleaning more frequently, as the conditions are perfect for the cultivation of bio-films and pollutants that spoil the flavour and pour of your pints.

The calibrated sensor on the SC Four constantly monitors the local cellar temperature, displaying the current reading on the unit’s LCD screen and storing reporting data on the device for later download.

Compact Design

The SC Four is a small and discreet device, measuring approximately 140mm x 100mm x 60mm.

Designed to treat 4 beer lines per unit, the SC Four is usually located close to the fob detector / cellar buoy. This ensures that there aren’t cables trailing around the cellar and also provides a temperature reading at a critical point in the dispense system.

In larger cellars, the compact design and 4 line treatment means that individual SC Four units are installed around the cellar. This also offers the added advantage of distributed cellar temperature monitoring, helping to identify any warm spots which may be impacting beer quality on certain lines.

Mobile App

StayClean have developed a mobile application on the Android platform. The app connects to the SC Four​ device via Bluetooth and provides environmental event notifications, most notable of which are safe temperature threshold breaches.

The threshold is set at 15 degrees Celsius and any instance of a temperature breach, which may impact the quality of the beer, is recorded and saved on the device. This data can then be downloaded via the Bluetooth connection for review and analysis.

Additional information, such as continuous run-time of the SC Four device, is also logged for download. This will help to identify any periods where the device has been switched off.

All data feeds can also be downloaded and emailed to StayClean for troubleshooting analysis.

It's #StayGreenAdvent Day3! Weekly line cleans in the UK result in around a million pints of #beer being poured down the sink each week – and profits with it. Install a Stayclean Unit, save beer and profits today and #StayGreen. #beer #sustainability https://t.co/Suiuc1cLdt cleanbeer photo

On Day2 of #StayGreenAdvent, we are looking at @Brewgoodr’s Global Gathering. In March 2020, 500 global breweries will unite to end #waterpoverty for 100,000 people. Find out more and register here: https://t.co/tdbvceRagh #BGG2020 #WaterEfficiency 💧

It's Day1 of #StayGreenAdvent. Each year, about 254million pints of #water are flushed away by UK pubs from weekly line cleans: an average 6,240 pints per pub. This waste could be quartered with a StayClean Unit - #StayGreen & save water today. #WorldWaterLossDay #WaterEfficiency https://t.co/EcAsLzQN6z cleanbeer photo

Today marks the beginning of our #StayCleanAdvent, where we will shine a light on some key environmental stats on the on-trade industry and highlight some great examples of #sustainable businesses in the sector! Have a happy (and eco-friendly) Christmas 🎄
