Our Technology


The Legionella Tech flushing unit sets new standards when it comes to protecting your people and safeguarding your reputation.


Utilising Radio Frequency

Our choice of 153MHz makes it easy to integrate into existing installations using the same frequency. It also offers a massive performance gain over the common 434MHz open frequency, with a 2km radius compared to just 200m. Low interference, more accurate readings and faster relaying of info are added benefits of 153MHz.

We’ve also developed our own unique ‘intelligent’ software, giving users the chance to create bespoke control programmes for enhanced performance and compliance. It means our system is proactive, not just reactive – a major advantage in the war against contamination.

Last but not least, we’ve used a 1-10v input for easy pairing with any number of different applications, ideal for triggering a flush routine or piggybacking information to the user. Our technology also comes with replaceable Li-on batteries

153MHz is a radio frequency legally licenced by OFCOM. Our equipment will always have exclusivity for the use of this bandwidth, all of our water treatment products within United Kingdom are 153MHz enabled. The bespoke frequency makes our product unique and unrivaled, some of these benefits include:

• 2Km’s range* on our flushing units and temperature transmitters.
• 10km’s range* with our repeater booster’s for large sites or where penetration through challenging environments (basements, lift shafts, concrete reinforced walls etc.) is required. Traditional open frequencies such as 434MHz are governed by OFCOM, any products utilising the frequency have to attenuate the signal and usually achieve a maximum range of 200m.
• 153MHZ is exclusive to Legionella-Tech, unlike other products on the market we have no issues with signal clash or saturation.

*line of sight


For our customers that require monitoring on smaller sites, we are able to offer our 434MHz range.

• 434MHz is an unlicensed frequency as such we are able to take advantage of mass manufacturing, which allows us in turn to pass savings on to our customers.
• Our equipment is tried and tested, we have a successful history of supplying, commissioning and servicing this range.
• Our 434MHz transmitters are smaller and more discreet making it ideal for small offices, retail plus many other locations where range is not a limiting factor.
