Events and venues

Big nights. Smaller energy bills.

Lighting, HVAC, bar fridges and cellar cooling run whether the house is full or the doors are locked. We cut that waste with voltage optimisation, KBR Refrigeration and CleanFlo, then prove every kWh in Pulse.

The problem

Doors open for a few hours. Your appliances run for all 24.

Even a busy venue only has a crowd in for a slice of the day. Lighting, HVAC, bar fridges, cellar cooling and beer coolers keep drawing power before doors, after close and on every dark day in the diary.

Then the pressure flips. Thousands of pints in a short interval, through lines that have sat still since the last show. That is where fobbing, slow serves and wasted beer come from.

Voltage optimisation

One install. The whole venue uses less.

UK mains often arrives well above the voltage your equipment is built for, and a stadium or arena pays for every extra volt across thousands of lights, motors and chillers. Voltage optimisation brings the whole site down to the level your kit runs best at. Nothing changes for the crowd, the bill just gets smaller.

  • HVAC, air handling and extraction
  • Escalators, lifts and pumps

KBR Refrigeration

Cooling that knows when the bar is open.

Refrigeration is usually the largest single electrical load behind a bar, and most of it runs flat out around the clock. KBR matches cooling to real demand and your event calendar, asset by asset, without letting temperatures drift.

Same temperatures

Thermocover probes read like the product, not the air, so compliance holds.

Follows your calendar

Cooling ramps down on dark days and is back to temperature before doors.

Fast payback

Typical return in 12 to 18 months, fitted with no downtime.

Energy and temperature side by side for auditors and brand owners.

CleanFlo beer line management New

No more fobbing at half time.

Bacteria in beer lines and fob detectors cause fobbing and spoil the taste, so standard lines need a full clean every 7 to 10 days. CleanFlo stops it at the source and your lines can go up to six weeks between cleans. Across dozens of lines in every bar, that is a lot of beer, labour and chemical you stop pouring away.

Ask about CleanFlo

Antimicrobial drop line

Made from an antimicrobial polymer, so bacteria cannot colonise the inside of the pipe.

TF Module fob detector

Vortex blades remove the still zones where bacteria breed. Beer lost per clean drops from a quarter pint to a tenth.

Yeast sediment trap

Catches free yeast before it reaches the tap. Zero fobbing was recorded in trade trials.

How much beer goes down the drain?

Every line clean flushes beer out of the line before the cleaning fluid goes in. Put in your own numbers and see what moving to six weekly cleans could keep in the glass.

Beer kept a year£2,580
Pints saved1,720
Cleans saved1,720

Compares your current cleans with one every six weeks (about 9 a year). Labour, chemical and water savings come on top. A guide only, we confirm the real figures on site.

Questions we get asked

Energy saving for venues, answered.

Why is voltage optimisation such a good fit for venues?

Stadiums, arenas and theatres run huge amounts of lighting, HVAC, motors and cooling, and UK mains often arrives at a higher voltage than that equipment needs. Voltage optimisation fits once at the incoming supply and brings the whole venue down to the right level, cutting electricity use by up to 15% with no change for your crowd or your shows. Lights and motors also run cooler, so they last longer.

How much energy can a venue save?

It depends on your supply voltage, how often you trade and how much refrigeration runs behind your bars. Voltage optimisation typically cuts site electricity by up to 15%, KBR usually pays back in 12 to 18 months and the Cellar Manager alone cuts primary cellar cooling by around 30%. We work out your own figure from half hourly data before we quote.

Will KBR affect beer or food temperatures?

No. KBR uses Thermocover probes that read like the product rather than the air, so the controller manages to the temperature that matters. Cellar and fridge temperatures are logged in Pulse, so you have records for EHOs, brand audits and your own quality checks.

What is CleanFlo and how does it stop fobbing?

CleanFlo is KBR's new beer line management system. It combines antimicrobial drop lines, TF Module fob detectors and a yeast sediment trap. Together they stop bacteria building up in the lines, which is what causes fobbing and off flavours. In trade trials with Greene King, tested by the University of Nottingham, bacteria fell by 99.98% and zero fobbing was recorded.

How often do beer lines need cleaning with CleanFlo?

Up to six weeks between cleans, compared with every 7 to 10 days on standard lines. For a venue with dozens of lines that means far less beer flushed away, less chemical and up to 80% less engineer time.

Can you install without affecting events?

Yes. We plan every install around your event calendar and fit on dark days or before doors. KBR units and CleanFlo parts go in without shutting bars, and voltage optimisation needs only a short planned isolation that we schedule with your facilities team.

Do you work with venue groups and multi site operators?

Yes. Every site reports into one Pulse account, so you can compare energy, cellar temperatures and savings across your whole estate. Many groups start with one venue, see the verified results and then roll out.
