Heat Exchanger Cleaning

Extensive range of cleaning processes and methods dedicated to high performance aviation and motorsport heat exchangers. All cooler core cleaning, flushing, filtration and drying processes are completed within an ISO Class 6 cleanroom environment, with high purity monitored fluids, positive pressure environment with realtime ambient particle monitoring.

Several processes are utilised for heat exchanger core cleaning, but the utmost priority will ensure the component integrity is not degraded. A range of cleaning processes are available within the laboratory including, steam wands, solvent flushing, aqueous flushing, slugging, CIP/SIP, flow benches, agitation, aeration, scrubbing and ultrasonic cleaning, with a selection of cleaners and solvents to suit customer needs.

All post flushing fluids for the final cleaning and filtration are sourced from an in-house water purification system, with filter retention levels to specific customer requirements, via a five stage filtration retention system from 100, 50, 10, 5 and 1 micron. Prior to final drying, a microscopic particle analysis is conducted to satisfy the customer target requirements, before a two stage drying process is applied to the internal and external surfaces via a forced flow system at controlled gas dew point.

Customer specified coatings can be applied with full vacuum and heat sealing prior to packaging and dispatch.
