Mechanical cleaning of smaller heat exchangers
Mechanical cleaning is a method, where a specific brush is rotated through the tubes. This creates friction, which loosens and removes dirt quickly and effectively. This is all powered by a machine with a flexible shaft.
With a (sometimes variable) speed and light water rinsing, cleaning will be as safe as possible. Not only for the contractor, but also for the heat exchanger itself. After all, there is no high pressure water involved.
