Unique and compact design

From a study on Hdo’s components and thanks to some technical implementations we have the ability 

to provide this reverse osmosis machine in a more silent version. It is possible to realize the silent version 

only on the 70 ,100 e GAS versions both LT and standard version. The main change is on the booster pump, 

with the consequential influence on the product (highest) and waste (lowest) ratio 

For this reason the installation of this machine is suggested in scenarios with the inlet water 

not exceeding 800 μS / cm, simply to avoid too much impact on membrane durability.
