Treatment of closed hot and chilled water loops is essential for the proper maintenance of heating, cooling, and piping systems.
Closed system water treatments aim to address the following:
- Corrosion control
- Scale/deposit build up
- Biological control
- Freeze Protection
- System Cleanings
Closed Loop Water Treatments
GWT-Inc offers a variety of treatment solutions for these systems. Our treatments are formulated using industry standard chemical formulations and blends.
General Information
- Any water treatment plan for closed systems should be evaluated by corrosion coupon monitoring.
- Periodic biological testing should be required for all closed systems.
- Side stream filtration is essential to reduce erosion and increase system efficiency.
Corrosion, scale, and deposit build up control
- Achieved through nitrite, molybdenum, or organo phosphonate based treatments. All of our formulations include adequate amounts of azole for soft metal control and have pH balancing properties.
- We also have custom blended formulations for aluminum boilers.
- We have custom formulations to fit almost any system requirement.
Biological Control
- Achieved through addition of biocides such as glutaraldehyde, bellacide 355 or another proven bacteria killers.
- In at high risk systems we recommend an annual system cleaning or dose of biocide.
Freeze Protection
- Achieved through ethylene or propylene glycol depending on system requirements and discharge regulations.
- Our glycols come in any percent mixture with or without inhibitors.
- We also offer greenER alternatives to the standard glycols on the market.
System Cleanings
- Achieved through mild cleaning compounds which penetrate deposit build up and scale on heat transfer surfaces.
