Boiler Water Treatment
Why do you need Boiler Water Treatment Chemicals?
Water Treatment chemicals are used to minimize corrosion and to prevent scale. By reducing corrosion and preventing scale, equipment life is prolonged and the equipment operates efficiently.What type of Boiler Water Chemical do I need?
Download our easy boiler selection guide
and choose the program you need.What are the most popular Boiler Chemicals?
For steam boilers Alkalinity
, Phosphates & Polymers
, and Amines
are the most popular. More advanced steam boiler systems have other chemicals. For hot water boilers or very low steam production boilers
, nitrite based products are the most popular.Where do we feed our Boiler Chemicals?
For steam boilers, ideally the Alkalinity
are feed to the center to the storage section of the deareator or feed water tank with long chemical injection quills. Polymers
should be feed to the drop leg of the deaerator
or feed water tank. Ideally, amines
should be fed to the center of the steam header. hot water boiler chemicals are commonly feed into a chemical pot feeder
.Why is pH important for Boiler Water Treatment?
The most popular pH builder is sodium hydroxide. This product is used as the boiler alkalinity
source. Boilers and Boiler Systems are primarily made of mild steel. At elevate temperatures, mild steel prefers higher pH waters. a higher pH will reduce your overall corrosion rates.Why do I need an Oxygen Scavenger?
The most popular Oxygen Scavenger is Sodium Sulfite. Even if you have a good operating deareator, sulfite should be fed to remove any dissolved oxygen in the boiler water. Dissolved oxygen at elevated temperatures and pressures becomes extremely corrosive. Failure to use a sulfite will lead to large localized corrosion pits and premature boiler tube failure.What are Amines?
DEHA, cyclohexamine, and morpholine
are the most popular steam treatment chemicals. Amines are used to increase the condensate pH. Steam exiting the boiler typically is low in pH
and is corrosive to the steam system. Why do I need a Polymer or Phosphate chemical?
Polymers and Phosphate are used in Boiler Water Treatment programs to prevent boiler scaling. Even if you have an excellent operating softener, small amounts of hardness will pass through the softeners
and softener upsets occur. Phosphates and Polymers are used to capture this hardness which prevents it from scaling to the boiler tubes. Bottom and surface blowdowns allows the capture hardness to exit the boiler. Failure to used a Phosphate or Polymer may lead to boiler scaling.How do I prevent Boiler Scale?
Always, always use a softener. Phosphates and polymers are used to capture small amount of hardness
. It is also more economical to use a softener.How do I remove Boiler Scale?
First, ask yourself why this occurred and be honest with yourself. It is easy to point fingers, but there are a lot of factors why boiler scaling occurred. The number one thing to do first is to shut the front door, that is stop adding hardness to the boiler. If you do not stop the hardness, you throwing money away and your problems will never go away. A few solutions may be install dual softener tanks in series, perform more hardness tests, check the hardness in the boiler daily, etc.
You can acid clean your boiler
, but let us warn you acid cleaning is expensive and if not properly performed can cause massive corrosion. Hire a professional if you are performing acid cleaning.
Your second choice is to use an acidic polymer
to gradually remove the boiler scale over time.How do I remove Rust in a Boiler?
Leave the rust alone! A lot of times the rust may be the only thing preventing the tubes from leaking. Accept the past and implement a solution to minimize the damaging starting today. If the pits are large and localized you have oxygen related problems, if it is a overall general boiler rust look at a pH or passivation solution. If you choose to remove the rust make sure to use a good iron removal chemical
.How come prices for Boiler Chemicals cover such a wide range?
A lot of boiler chemical
companies build the cost of monthly visits in the costs of the chemicals. You water treatment service representative must be paid for his time. Nothing is for free. If you value his service and their price is right, there is no need to shop around. You can use our prices as a quick check to see if you are being over charged.How can I simply my Boiler Water Treatment Program?
If you are using 3 or 4 drum
Boiler Water Treatment chemicals and your boiler system is large, it is the most cost effective way. Stick with it. If you have an smaller Boiler Water System, you may switch to an all-in-one
boiler water treatment program. These chemicals are less concentrated since they have to be stable and have to keep all the components in solution instead of precipitating out.Do I need to perform chemical testing?
Testing should always be performed to establish a base line of how much boiler chemicals should be used. Always monitor boiler chemical usage and logsheets
to establish a history so trouble shooting may be performed when problems arise. For larger boilers, always use a boiler conductivity controller

Cooling Water Treatment
Why do I Cooling Water Treatment chemicals??Cooling Water Treatment chemicals
are used to minimize corrosion and scale
and to kill bacteria
development. Chillers use a Nitrite based product to prevent corrosion.What are the most common Cooling Water Treatment chemicals?
All organic corrosion and scaling chemicals are very popular. The most common biocides are non-oxidizers and oxidizers. Non-oxidizers include Isothiazolin
, Oxidizers are stabilized bromide chlorine
and sodium hypochlorite
.What is a Cooling Water Treatment Biocide?
is used to kill bacteria
. Bacteria will form in most water systems and some form of bacteria must be used to kill off bacteria. Bacteria is water systems is dangerous to humans and may causes a list of process problems.What are common Scale and Corrosion chemicals?
All organic corrosion and scaling chemicals are commonly used for moderate water conditions. For more complex waters, there are different chemicals that may be used. How do I remove Cooling Water Scale?Inhibited Sulfamic Acid
may be used to remove scaling. If you are removing scaling in a chiller
system isolate the chiller from the process before cleaning. Where do I feed my Cooling Water Treatment chemicals?
Feed the scale and corrosion cooling water chemical as more water is added and dumped from the system. Oxidizers should be on a daily basis and non-oxidizers on an as needed basis. Use dipslides
to check for active bacteria.How much of each chemical do I feed?Cooling Water Treatment chemicals
require low relatively low ppm of chemical residuals. For an all organic cooling water treatment program, 10 to 15 ppm or organphosphonate
. A free chlorine rate should always be maintained in recirculating cooling water systems open to the air. Always consider purchasing a complete cooling water test kit
if you are just getting started.How come prices for Cooling Water Chemicals cover such a wide range?
Many chemical companies build the cost of service visits into the chemicals. The water treatment service representative must be paid for his time. If you value his service and their price is right, there is no need to shop around. You can use our prices as a quick check to see if you are being over charged.
Do I need to perform chemical testing?
