A few years ago, an engineer working for a“friend’s plant” chose to replace their evaporative condenser with an adiabatic condenser. On the surface, the choice seemed like a good idea since adiabatic condensers often provide higher heat rejection with lower water and electricity usage. The condenser was purchased and installed, but all was not well. When not carefully considered, replacing equipment or control programs can have unforeseen consequences such as negative impacts on operational safety.
In this real life example the author examines what information would have made a big difference and significant savings had the right questions been asked.
