Provisional new-series slug: /compressed-air-engineering/cooler-heat-exchanger-service-thermal-restoration-fouling-control/ | CTA: Review My Compressor Cooling System

Do not clean a heat exchanger just because the compressor is hot. first prove the heat source, the cooling path and the fouling mechanism

A high-temperature symptom can come from the exchanger, but it can also originate in airflow, cooling-water supply, recirculation, intake restriction, thermostat/bypass behaviour, lubricant condition, pressure/load or instrumentation.

The cleaning method follows the exchanger material and contaminant. Dust, oil film, scale, biological fouling boundary, corrosion products and process contamination do not justify one universal cleaning method. Exact chemistry, concentration, pressure, temperature, dwell time, flushing, tube-cleaning method and acceptance limit require current equipment/material data and competent review.

154 — Fouling Mechanism Determines Method

Dust, oil film, scale and other deposits are not equivalent. Cleaning should be selected from material and fouling evidence rather than habit.
