An alternative to ultrasonic cleaning is also available:
Vestas has developed a new, safer alternative to ultrasonic cleaning. A specially formulated foam reaches the entire external surface of the air cooler and is left pumping through the fins until the coolers is clean. The contaminated foam turns to liquid and is dealt with via normal separation processes to ensure there is no environmental impact.
The cleaning facility is in Denmark. We will collect from any Northern European location, and return the cooler cleaned and tested. Where appropriate, an inspection report will be made FOC.
