Boiler water treatment chemical programs

Ensure the safe and optimal operation of your boiler while protecting assets with Hydrex®


Corrosion, scaling and fouling can reduce the operating efficiency of your boiler and compromise the performance of all the systems connected to the water and steam circuits, causing downtimes and increasing the total cost of operation. Hydrex chemical solutions for boiler water treatment combine selected formulations, equipment, real-time monitoring and service to prevent these situations from occuring. 



To define the optimal conditioning strategy, the Hydrex boiler water treatment program starts with a risk assessment to evaluate make-up water and feedwater quality, system configuration (pretreatment, boiler characteristics, pressure, norms, etc.) and operating conditions, taking all the parameters and constraints into consideration. The objectives of the program are: 


heat picto

To prevent the formation of deposits that could damage the heat transfer and to ensure the long-term protection of assets.


air quality picto

To fix the pH conditions and remove any dissolved oxygen – a constant threat to boiler feedwater systems, internal boilers and condensate systems.


steam picto

To reach sufficient steam quality for the targeted use (no carry-over nor silica).

piping picto

To get non-aggressive condensates with respect to return piping.


graphic picto

To optimize the consumption of chemicals, energy and water by using simulation tools to calculate the potential savings along with online analyzers to measure and manage performance.



To reach maximum operator safety and sustainability by using the most environmentally friendly techniques. 

In addition to boiler water treatment programs, our industrial water treatment specialists can provide you with efficient solutions to pretreat boiler feedwater such as:
