Immersion Heater Role and Types for Water Purification, Part 1

August 11, 2020
by Gordo Sales Team

For numerous industrial processes, water purification is an important factor that must be considered closely. Many applications, from medical areas to chemical plants and plenty of others, require clean and potable water, and immersion heaters help carry out several parts of this process.

At Gordo Sales, we’re happy to provide a wide range of immersion heaters and other industrial heating systems, including our Tempco 55-gallon metal drum immersion heater and many additional options. What role do immersion heaters play in water purification in your industrial facility, and which type of immersion heater will be best given your purification and additional needs? This two-part blog series will dig into each of these factors and more.

Distribution Loop Sanitation

Part of standard maintenance for any water purification system will involve sanitation, and immersion heaters play a role here. They help raise up the temperature of the water being flushed into the distribution loop and storage tank, which in turn helps kill bacteria or other contaminants that might be present.

Now, there are other methods that can be used for such sanitation, including ozone or various chemical sanitation methods. However, heat sanitation with water is ideal because it requires no chemical handling or rinsing, and flushing the system is safer, faster and more effective from a sanitation perspective.

Tank Sanitation

Another area where sanitation is important is within the activated carbon tank, which is often used for water that will be consumed by humans. These tanks can remove chlorine, organics and other elements that may impact taste or smell in the water.

However, these tanks themselves also need to be sanitized to perform properly. Again, the immersion heater is the ideal option here, heating water to sanitize the active carbon tank.

Water Preheating

There are also numerous chemical processes that will require water purification, such as clean-in-place processes. Many of these are far more efficient with immersion heaters than other types, allowing for heating of the chemical mixture that speeds up the entire process.

Thermal Pasteurization

Finally, thermal pasteurization is a process sometimes used to kill of various pathogens or extend a product’s shelf life. One common bacteria it is effective against is legionella bacteria, which is known to cause Legionanaires’ disease. It involves liquid products being treated with water and steam – and this water and steam will generally come from an immersion heater, which will allow for the proper levels of heat.

In part two of our series, we’ll dig into several ideal immersion heater formats to consider for your water purification needs. For more on this or any of our process heating services, speak to the staff at Gordo Sales today.
