Our proven range of Film Forming Amine closed circuit inhibitors comprises formulations for systems manufactured from iron-based metals and yellow metals with specific formulations also designed for use in multi-metal systems.
Formulations are also available which effectively treat notably difficult semi-closed systems such as those cooling aluminium moulds. Mould corrosion and microbiological contamination are just two of the major issues with these systems that the use of biostable polyamine inhibitors can effectively overcome.
Polyamines are also compatible with Glycols so can be used effectively in chiller systems. The biostable nature of the polyamine inhibitor formulations is important in chillers where microbiological contamination can be a major issue if glycol levels fall below 20%.
The UK is experiencing a dramatic increase in the number of low-carbon district heating networks and this is expected to continue. A recent report by the Climate Change Committee estimated that around 18% of UK heat could come from district heating networks by 2050. The low dose rates, extremely effective corrosion inhibition, and low environmental impact of using polyamines mean that this type of treatment is preferred for this type of system in many European countries.
Why choose FFA inhibitors for Closed-circuit systems?
All-in-One Solution: All in one low dose treatment– no requirement for biocide additions
- Reduced costs associated with purchasing, logistics, handling, and storage of chemicals.
Enhanced Heat Transfer Efficiency: Removal of corrosion deposits on heat transfer surfaces creating cleaner/smoother surfaces, allowing for more efficient heat transfer.
Superior Corrosion Control: Polyamines provide a stable and reliable film that resists degradation, where underdosing or overdosing is less critical once the film is established.
- Traditional nitrite inhibitors are prone to bacterial degradation and can induce microbiological issues if not dosed correctly. Underdosing can also lead to pitting corrosion.
- Traditional molybdate inhibitors are expensive and rapidly deplete in systems with heavy corrosion.
- Protective film makes the system less sensitive to changes in water conditions, such as contamination or pH fluctuations.
- The robust protective film is especially beneficial for systems with intermittent operation.
Cost-Effective Treatment: Treat the metal surface rather than the entire volume of water within a system
- Smaller quantities of chemical needed = lower treatment costs, making it a more cost-effective solution.
Enhanced Equipment Lifespan:
- Film-forming polyamines extend boiler and pipework lifespan, minimize corrosion, and reduce maintenance costs, ensuring long-term financial savings.
Environmentally Friendly: Polyamines are a more environmentally friendly alternative to traditional treatments
- Reduced chemical consumption, and reduced handling of hazardous chemicals.
- On discharge the polyamine formulations are biodegradable, unlike traditional inhibitor chemicals.
