Tube bundle or complete heat exchanger is serviced at one of our service facilities. A mild acid solution is pumped through the heat exchanger for 6-8 hours, during the flushing all debris is collected in the filter. Before and after flow rates are recorded to gauge the effectiveness of the cleaning.
Extreme fouling applications - tube bundle is submerged in a heated chemical bath.
After 4 hours the bundle is removed and high pressure washed.
If the contamination remains the process is repeated.
