COOLING TOWER WATER TREATMENT CHEMICALS
corrosion and scale inhibitors
Smart Release Technology tablets provide consistent, controlled protection against harmful corrosion and scale.
FIGHT HARMFUL CORROSION AND SCALE IN YOUR SYSTEM
You need to mitigate corrosion and scale to keep your cooling tower system running smoothly and efficiently.
Scale and corrosion negatively impact your system's heat transfer capabilities and can promote microbial growth.
With Dober's tablet technology, your system can combat harmful scale and corrosion and ultimately help save you time, money and storage space.
Depending on your specific needs, take a look at our technical data sheets (TDS) at the bottom of this page for more information about our corrosion and scale inhibitor tablet offerings.
If you have questions about which corrosion and scale tablet might be the right one for you, reach out to a Smart Release expert.
