When “this is how we’ve always done it”
is the most expensive choice

Yes, it is possible to get the best of both worlds. Apurgo has systems that remove and prevent bacteria and fouling, while, at the same time, providing major energy savings.

Great energy savings

Apurgo M3 is the system for those who want a long-lasting and effective water treatment that provides great energy efficiency – with protection against Legionella. Apurgo M3 treats the water downstream from the main water intake, preventing and removing Legionella throughout the plant, both on the cold and hot water side.


The treatment is not temperature dependent, allowing you to lower the hot water temperature from 70 to 50 °C, which will improve the energy efficiency of your buildings. The system can be adapted to all buildings, regardless of their water consumption, and it also removes biofilm. In this way, you avoid demanding and expensive periodical hot water flushing or chemical cleaning to keep the facility bacteria-free and safe. Thus, HSE risks of handling chemicals and the risk of scalding during hot water flushing will be a thing of the past.

More efficient energy systems

Heat&Cool Smart is our solution to ensure continuous optimal water quality in your closed-loop energy systems, which, in turn, ensures the best possible energy efficiency. With Heat&Cool Smart, you reduce the need for maintenance, and you can always be sure to have the right pH, continuous filtration, and the right pressure.


By continuously monitoring the energy system, we can predict potential problems and, in advance, see if measures should be taken. This ensures that the plant always has the desired functionality and effect. The predictive technology of Heat&Cool Smart maintains the quality of your energy system, extends its life, and contributes to great energy savings.

Operational monitoring 24/7

Both Apurgo M3, Apurgo Clean and Heat&Cool Smart are connected to our cloud solution, Apurgo Cloud, which provides operational monitoring 24/7. This means that we can quickly notify you if there is something that needs immediate attention, such as a water leak, need for filter replacement, pressure drops, changes in water quality, or other tasks or issues that need to be followed up.
