HEAT EXCHANGER EXTERIOR SURFACE CLEANING SYSTEM, METHOD OF RETROFITTING A HEAT EXCHANGER WITH A CLEANING SYSTEM, AND METHOD OF CLEANING A HEAT EXCHANGER

Abstract:

A cleaning system may be used with a heat exchanger having a core and a fan. The core may include a first core face and an oppositely disposed second core face. The cleaning system may include a plurality of wash nozzles arranged between the first core face and the fan of the heat exchanger. The cleaning system may be used while the heat exchanger is in operation, reducing the downtime of the heat exchanger. A method of retrofitting a heat exchanger with a cleaning system may include arranging a plurality of wash nozzles between the first core face and the fan of the heat exchanger. A method of cleaning a heat exchanger may include arranging a plurality of wash nozzles between the first core face and the fan, supplying a cleaning fluid to the plurality of nozzles, and initiating a cleaning cycle while the heat exchanger is in operation so that the fan assists in moving the cleaning fluid through the core and removing accumulated debris from the second core face.
