A 2.5MW steam-fired absorption chiller installed in 1997 was operating with very poor performance due to various failures over the years. With its unreliable performance, the customer faced a decisive phase—whether to replace or repair the chiller.
We intervened at the right time, discovering that the Lithium Bromide specifications were out of range, specifically in terms of the inhibitor and alkalinity. We also found iron oxide and copper corrosion within the chiller, blocking the internal heat exchangers and spray system. Using our thermal imaging system, we identified that one of the heat exchangers was leaking liquid internally.
After addressing the heat exchanger issue and performing six months of online Lithium Bromide filtration with chemical correction, the chiller is now back in operation, saving the significant cost of a replacement.
