B&V's proven range of polyamine closed circuit inhibitors comprise 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. In the past, these systems have posed numerous problems when using conventional molybdate, nitrite and phosphate based inhibitors, with phosphate and nitrite being particularly prone to degradation by bacteria. 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. In 2014, only 2% of homes were connected to a heat network in line with the government’s Net-Zero Strategy and a recent report by the Climate Change Committee which 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 from using polyamines means that this type of treatment is preferred for this type of system in many European countries.
All in one low dose treatment for closed circuit systems – no requirement for biocide additions.
Removal of corrosion deposits on heat transfer surfaces creating cleaner/smoother surfaces, allowing for more efficient heat transfer.
Reducing the Total Dissolved Solids (TDS) contribution from chemical products.
Polyamines provide a stable and reliable film that resists degradation, where under dosing or over dosing is less critical once the film is established.
Treat the metal surface rather than the entire volume of water within a system
Polyamines provide a more environmentally friendly alternative to traditional treatments for several reasons as discussed above.
