Corrosion and the hindrance of heat transfer caused by fouling in heat exchangers are the main reasons for an increase in energy, operating and maintenance costs of a generator. That’s why coolers must be inspected, cleaned and tested on a regular basis. Our standard cleaning and diagnostic service includes a hydrostatic test of the coolers in the received condition (to identify any leaks), a general steam cleaning, replacement gaskets when applicable, and a written initial and final test report. Regardless of initial test results, the water/headers are removed for evaluation. At that point Unifin issues a set of recommendations and work scope.
