VRcooler is used mainly on air condensers and air cooled heat exchangers, air cooled fin fan heat exchanger (fin fan).
It facilitates dry-cleaning, both online and offline, if external heat exchange surfaces (finned tubes) clogged by deposits (oil residues, resins, various atmospheric waste, etc.).
VRcooler is projected with low-pressure compressed air directly on to the fins. It cleans metallic surfaces quickly and causes no abrasion. It has the benefit of requiring no further engine protection nor any scaffolding.
Process is used in particular on “critical” air cooled fin fan heat exchanger, restoring operational characteristics that are close to design values.
